aggr - jikkmanda għall-ġestjoni aggregati, li juri l-istatus aggregata, u aggregati ikkupjar l-argument kmand aggr ... Il-familja kmand aggr tamministra aggregati. Il-kmandijiet aggr tista 'toħloq aggregati ġodda, jeqirdu dawk eżistenti, aggregat undestroy qabel meqruda, jimmaniġġjaw plexes fi aggregat riflessa, tibdil fl-istat aggregat, japplikaw l-għażliet għal aggregat, kopja waħda aggregat għall-ieħor, u l-wiri l-istatus tagħhom. Jikkmanda aggregat ta 'spiss jaffettwaw il-volum (i) li jinsabu fi ħdan aggregati. Il-familja kmand aggr huwa ġdid fil Data ONTAP 7.0. Il-familja kmand vol basta kontroll fuq l-mes U tradizzjonali vol_ li mdewba wieħed mill-utent viżibbli fajl tas-sistema u wieħed RAID-livell ħażna tal-kontenituri (aggregati) fi unità indiviżibbli, u għadhom ma. Biex jippermettu użu aktar flessibbli ta 'ħażna, l-aggregati issa wkoll tappoġġja l-kapaċità li jkun fihom, indipendenti multipli utent livell sistemi fajl imsemmi volumi flessibbli.
Data ONTAP 7.0 jappoġġja bis-sħiħ iż-żewġ volumi tradizzjonali u flessibbli. Il-familja kmand aggr huwa l-metodu preferut għall-ġestjoni aggregati a filer, inklużi dawk li huma integrati fil-volumi tradizzjonali.
Innota li ħafna mill-kmandi aggr japplikaw ugwalment għaż-żewġ-tip ta 'aggregati li fiha volumi flessibbli u t-tip li hija strettament marbuta li jiffurmaw volum tradizzjonali. Għalhekk, l-aggregat terminu hija spiss użata hawn biex jirreferi għaż-żewġ klassijiet ta 'ħażna. F'dawk il-każijiet, tipprovdi fil-qosor għal l-itwal u aktar dens frażi "l-aggregati u l-volumi tradizzjonali".
Aggregati jistgħu jew jiġu riflessi jew unmirrored. A plessi hija kopja fiżika tal-ħażna WAFL fi ħdan l-aggregat. A aggregat riflessa tikkonsisti f'żewġ plexes; aggregati unmirrored fihom plessi wieħed. Sabiex jinħoloq aggregat riflessa, irid ikollok konfigurazzjoni filer li jappoġġja RAID-livell riflessjoni. Meta duplikazzjoni hija ppermettiet fuq il-filer, il-diski parts huma maqsuma pools disk tnejn. Meta aggregat huwa maħluq, kollha tal-diski fl-plessi wieħed għandu jiġi mill-pool istess diska, u l-plexes żewġ ta 'aggregat riflessa għandu jikkonsisti diski minn pools separati, għaliex dan jimmassimizza iżolament tort. Din il-politika tista 'tiġi megħluba bil-f-għażla li aggr joħolqu, aggr żid u mera aggr, iżda mhuwiex rakkomandat.
Isem aggregat jista 'jkun fihom ittri, numri, u l-karattru jenfasizzaw (_), iżda l-ewwel karattru għandu jkun ta' ittra jew enfasizzati. A total kombinat ta 'sa 200 aggregati (inklużi dawk inkorporati fil-volumi tradizzjonali) jistgħu jiġu maħluqa fuq kull filer.
A plessi tista 'tkun online jew offline. Jekk huwa offline, ma jkunx disponibbli għall jaqraw jew jiktbu aċċess. Plexes jista 'jkun fil-kombinazzjonijiet ta' l-istati li ġejjin:

A plessi huwa msemmi jużaw l-isem ta 'l-aggregat, il delimetru karattru mmejla, u l-isem tal-plessi. Is-sistema awtomatikament tagħżel ismijiet plessi fil-ħin ħolqien. Per eżempju, l-plessi ewwel maħluqa fl aggr0 aggregat ikun aggr0/plex0.
Aggregat jista 'jkun fuq l-internet, ristretta, jew offline. Meta aggregat offline, l-ebda taqra jew tikteb l-aċċess huwa permess. Meta aggregat huwa ristrett, ċerti operazzjonijiet huma permessi (bħal kopja aggregat, komputazzjoni mill-ġdid jew rikostruzzjoni RAID parità) iżda aċċess għad-data ma jkunx permess. Aggregati li mhumiex parti ta 'volum tradizzjonali tista' biss tkun ristretta jew offlined jekk dawn ma jkunx fihom kull volum flessibbli.

Iżżid diski għall-aggrname aggregat msemmija. Speċifika l-diski bl-istess mod kif għall-kmand aggr joħolqu. Jekk l-aggregat huwa rifless, allura l-argument għandu d jintuża darbtejn (jekk xejn). Jekk il-g-għażla ma tkunx użata, il-diski huma miżjuda mal-aktar reċentement ħolqot grupp Util RAID huwa sħiħ, u mbagħad wieħed jew aktar gruppi RAID ġodda huma maħluqa u l-diski li fadal huma miżjuda ma 'gruppi ġodda. Gruppi oħra eżistenti RAID li mhumiex sħiħa jibqgħu parzjalment mimli.
-G-għażla tippermetti ispeċifikazzjoni ta 'grupp RAID (per eżempju, rg0) li l-diski indikat għandu jkun miżjud, jew metodu li bih il-diski huma miżjuda mal-gruppi RAID ġodda jew eżistenti.

Joħloq sistema ġdida aggrname aggregata msemmija. L-isem aggregat jista 'jkun fihom ittri, numri, u l-karattru jenfasizzaw (_), iżda l-ewwel karattru għandu jkun ta' ittra jew enfasizzati. Sa 200 aggregati jistgħu jiġu maħluqa fuq kull filer. Dan in-numru jinkludi dawk l-aggregati li jinsabu fi ħdan il-volumi tradizzjonali. Aggregat integrati jistgħu jinħolqu bħala parti ta 'volum tradizzjonali bl-użu tal vs-għażla. Ma jistax ikun fihom kull volum flessibbli.
A aggregat regolari, maħluqa mingħajr il-vs-għażla, jista 'jkun fihom biss volumi flessibbli. Ma jistax jiġi inkorporat fis-volum tradizzjonali, u fih l-ebda volumi immedjatament wara l-ħolqien. Volumi flessibbli ġdida tista 'tkun maħluqa bl-użu tal-kmand joħolqu vol.
L-argument t raidtype tispeċifika t-tip ta 'RAID grupp (i) li għandhom jintużaw biex joħolqu l-aggregat. It-tipi possibbli grupp RAID huma raid4 għal RAID-4, raid_dp għal RAID-DP (Parità Double), u raid0 għall striping sempliċi mingħajr protezzjoni parità. The raidtype default għall-aggregati u l-volumi tradizzjonali fuq filers huwa raid_dp. Twaqqif tal-raidtype mhux permess fuq il-V-Serje sistemi; in-nuqqas tat raid0 huwa dejjem użat.
-R-argument raidsize jispeċifika n-numru massimu ta 'diski f'kull grupp RAID fl-aggregat. Il-valuri massimi u nuqqas ta 'raidsize huma pjattaforma dipendenti, ibbażata fuq il-prestazzjoni u l-konsiderazzjonijiet affidabbiltà. Tara l-għażliet aggr raidsize għal aktar dettalji.
It-T-diska tat-tip l-argument tispeċifika t-tip ta 'diski li jużaw meta jinħoloq aggregat ġdid. Huwa meħtieġ biss fuq is-sistemi konnessi ma 'diski ta' tipi differenti. Tipi disk possibbli huma: ATA, FCAL, Lun, SAS, SATA, u SCSI. Diski It-taħlit ta 'tipi differenti wieħed aggregat mhux permess. T ma jistax jiġi użat flimkien ma' d.
Tip disk jidentifika teknoloġija disk u t-tip konnettività. ATA jidentifika diski ATA ma 'jew IDE jew serial interface ATA fl-ixkafef konnessi FCAL (Kanal Fibra arbitraġġ Loop). FCAL jidentifika diski FC fl-ixkafef konnessi FC AL. Lun tidentifika diski virtwali esportati mill- matriċi estern tal-ħażna. The underlying disk technology and RAID type depends on implementation of such external storage arrays. SAS identifies Serial Attached SCSI disks in matching shelves. SATA identifies serial ATA disks in SAS shelves. SCSI stands for Small Computer System Interface, and it is included for backward compatibility with earlier disk technologies.
The -R rpm argument specifies the type of disks to use based on their rotational speed in revolutions per minute (rpm). It is needed only on systems having disks with different rotational speeds. Typical values for rotational speed are 5400, 7200, 10000, and 15000. -R cannot be used together with -d .
ndisks is the number of disks in the aggregate, including the parity disks. The disks in this newly created aggregate come from the pool of spare disks. The smallest disks in this pool join the aggregate first, unless you specify the @ size argument. size is the disk size in GB, and disks that are within 10% of the specified size will be selected for use in the aggregate.
The -m option can be used to specify that the new aggregate be mirrored (have two plexes) upon creation. If this option is given, then the indicated disks will be split across the two plexes. By default, the new aggregate will not be mirrored.
The -n option can be used to display the command that the system will execute, without actually making any changes. This is useful for displaying the automatically selected disks, for example.
If you use the -d disk1 [ disk2 ... ] argument, the filer creates the aggregate with the specified spare disks disk1 , disk2 , and so on. You can specify a space-separated list of disk names. Two separate lists must be specified if the new aggregate is mirrored. In the case that the new aggregate is mirrored, the indicated disks must result in an equal number of disks on each new plex.
The disks in a plex are not permitted to span spare pools. This behavior can be overridden with the -f option. The same option can also be used to force using disks that do not have matching rotational speed. The -f option has effect only when used with the -d option specifying disks to use.
To create a SnapLock aggregate, specify the -L flag with the aggr create command. This flag is only supported if either SnapLock Compliance or SnapLock Enterprise is licensed. The type of the SnapLock aggregate created, either Compliance or Enterprise, is determined by the installed SnapLock license. If both SnapLock Compliance and SnapLock Enterprise are licensed, use -L compliance or -L enterprise to specify the desired aggregate type.
The -l language_code argument may be used only when creating a traditional volume using option -v . The filer creates the traditional volume with the language specified by the language code. The default is the language used by the filer's root volume. See the vol man page for a list of language codes.
aggr destroy { aggrname | plexname } [ -f ]
Destroys the aggregate named aggrname , or the plex named plexname . Note that if the specified aggregate is tied to a traditional volume, then the traditional volume itself is destroyed as well.
If an aggregate is specified, all plexes in the aggregate are destroyed. The named aggregate must also not contain any flexible volumes, regardless of their mount state (online, restricted, or offline). If a plex is specified, the plex is destroyed, leaving an unmirrored aggregate or traditional volume containing the remaining plex. Before destroying the aggregate, traditional volume or plex, the user is prompted to confirm the operation. The -f flag can be used to destroy an aggregate, traditional volume or plex without prompting the user.
The disks originally in the destroyed object become spare disks. Only offline aggregates, traditional volumes and plexes can be destroyed.
aggr media_scrub status [ aggrname | plexname | groupname ]
[ -v ]
Prints the media scrubbing status of the named aggregate, plex, or group. If no name is given, then status is printed for all RAID groups currently running a media scrub. The status includes a percent-complete and whether it is suspended.
The -v flag displays the date and time at which the last full media scrub completed, the date and time at which the current instance of media scrubbing started, and the current status of the named aggregate, plex, or group. If no name is given, this more verbose status is printed for all RAID groups with active media scrubs.
aggr mirror aggrname
[ -f ]
[ -n ]
[ -v victim_aggrname ]
[ -d disk1 [ disk2 ... ] ]
Turns an unmirrored aggregate into a mirrored aggregate by adding a plex to it. The plex is either newly-formed from disks chosen from a spare pool, or, if the -v option is specified, is taken from another existing unmirrored aggregate. Aggregate aggrname must currently be unmirrored. Use aggr create to make a new, mirrored aggregate from scratch.
Disks may be specified explicitly using -d in the same way as with the aggr create and aggr add commands. The number of disks indicated must match the number present on the existing aggregate. The disks specified are not permitted to span disk pools. This behavior can be overridden with the -f option. The -f option, in combination with -d , can also be used to force using disks that have a rotational speed that does not match that of the majority of existing disks in the aggregate.
If disks are not specified explicitly, then disks are automatically selected to match those in the aggregate's existing plex.
The -v option can be used to join victim_aggrname back into aggrname to form a mirrored aggregate. The result is a mirrored aggregate named aggrname which is otherwise identical to aggrname before the operation. Victim_aggrname is effectively destroyed. Victim_aggrname must have been previously mirrored with aggrname , then separated via the aggr split command. Victim_aggrname must be offline. Combined with the -v option, the -f option can be used to join aggrname and vic_ t im_aggrname without prompting the user.
The -n option can be used to display the command that the system will execute without actually making any changes. This is useful for displaying the automatically selected disks, for example.
aggr offline { aggrname | plexname }
[ -t cifsdelaytime ]
Takes the aggregate named aggrname (or the plex named plexname ) offline. The command takes effect before returning. If the aggregate is already in restricted state, then it is already unavailable for data access, and much of the following description does not apply.
If the aggregate contains any flexible volumes, then the operation is aborted unless the filer is in maintenance mode.
Except in maintenance mode, the aggregate containing the current root volume may not be taken offline. An aggregate containing a volume that has been marked to become root (using vol options vol_ n ame root ) also cannot be taken offline.
If the aggregate is embedded in a traditional volume that has CIFS shares, users should be warned before taking the aggregate (and hence the entire traditional volume) offline. Use the -t switch for this. The cifsdelaytime argument specifies the number of minutes to delay before taking the embedded aggregate offline, during which time CIFS users of the traditional volume are warned of the pending loss of service. A time of 0 means take the aggregate offline immediately with no warnings given. CIFS users can lose data if they are not given a chance to terminate applications gracefully.
If a plexname is specified, the plex must be part of a mirrored aggregate and both plexes must be online. Prior to offlining a plex, the system will flush all internally-buffered data associated with the plex and create a snapshot that is written out to both plexes. The snapshot allows for efficient resynchronization when the plex is subsequently brought back online.
A number of operations being performed on the aggregate's traditional volume can prevent aggr offline from succeeding, for various lengths of time. If such operations are found, there will be a one-second wait for such operations to finish. If they do not, the command is aborted.
A check is also made for files in the aggregate's associated traditional volume opened by internal ONTAP processes. The command is aborted if any are found.
aggr online { aggrname | plexname }
[ -f ]
Brings the aggregate named aggrname (or the plex named plexname ) online. This command takes effect immediately. If the specified aggregate is embedded in a traditional volume, the volume is also also brought online.
If an aggrname is specified, it must be currently offline, restricted, or foreign. If the aggregate is foreign, it will be made native before being brought online. A “foreign” aggregate is an aggregate that consists of disks moved from another filer and that has never been brought online on the current filer. Aggregates that are not foreign are considered “native.”
If the aggregate is inconsistent, but has not lost data, the user will be cautioned and prompted before bringing the aggregate online. The -f flag can be used to override this behavior. It is advisable to run WAFL_check (or do a snapmirror initialize in case of an aggregate embedded in a traditional volume) prior to bringing an inconsistent aggregate online. Bringing an inconsistent aggregate online increases the risk of further file system corruption. If the aggregate is inconsistent and has experienced possible loss of data, it cannot be brought online unless WAFL_check (or snapmirror initialize in the embedded case) has been run on the aggregate.
If a plexname is specified, the plex must be part of an online mirrored aggregate. The system will initiate resynchronization of the plex as part of online processing.
aggr options aggrname [ optname optval ]
Displays the options that have been set for aggregate aggrname , or sets the option named optname of the aggregate named aggrname to the value optval . The command remains effective after the filer is rebooted, so there is no need to add aggr options commands to the /etc/rc file. Some options have values that are numbers. Some options have values that may be on (which can also be expressed as yes , true , or 1 ) or off (which can also be expressed as no , false , or 0 ). A mixture of uppercase and lowercase characters can be used when typing the value of an option. The aggr status command displays the options that are set per aggregate.
The following describes the options and their possible values:
fs_size_fixed on | off
This option only applies to aggregates that are embedded in traditional volumes. It causes the file system to remain the same size and not grow or shrink when a SnapMirrored volume relationship is broken, or an aggr add is performed on it. This option is automatically set to be on when a traditional volume becomes a SnapMirrored volume. It will remain on after the snapmirror break command is issued for the traditional volume. This allows a traditional volume to be SnapMirrored back to the source without needing to add disks to the source traditional volume. If the traditional volume size is larger than the file system size, turning off this option will force the file system to grow to the size of the traditional volume. The default setting is off .
ignore_inconsistent on | off
This command can only be used in maintenance mode. If this option is set, it allows the aggregate containing the root volume to be brought online on booting, even though it is inconsistent. The user is cautioned that bringing it online prior to running WAFL_check or wafliron may result in further file system inconsistency.
nosnap on | off
If this option is on , it disables automatic snapshots on the aggregate. The default setting is off .
raidsize number
The value of this option is the maximum size of a RAID group that can be created in the aggregate. Changing the value of this option will not cause existing RAID groups to grow or shrink; it will only affect whether more disks will be added to the last existing RAID group and how large new RAID groups will be.
Legal values for this option depend on raidtype . For example, raid_dp allows larger RAID groups than raid4 . Limits and default values are also different for different types of filer appliances and different types of disks. Following tables define limits and default values for raidsize .
—————————————— raid4 raidsize min default max —————————————— R100 2 8 8 R150 2 6 6 FAS250 2 7 14 other (FCAL disks) 2 8 14 other (ATA disks) 2 7 7 —————————————— —————————————— raid_dp raidsize min default max —————————————— R100 3 12 12 R150 3 12 16 other (FCAL disks) 3 16 28 other (ATA disks) 3 14 16 ——————————————
Those values may change in future releases of Data ONTAP.
raidtype raid4 | raid_dp | raid0
Sets the type of RAID used to protect against disk failures. Use of raid4 provides one parity disk per RAID group, while raid_dp provides two. Changing this option immediately changes the RAID type of all RAID groups within the aggregate. When upgrading RAID groups from raid4 to raid_dp , each RAID group begins a reconstruction onto a spare disk allocated for the second `dparity' parity disk.
Changing this option also changes raidsize to a more suitable value for new raidtype . When upgrading from raid4 to raid_dp , raidsize will be increased to the default value for raid_dp . When downgrading from raid_dp to raid4 , raidsize will be decreased to the size of the largest existing RAID group if it is between the default value and the limit for raid4 . If the largest RAID group is above the limit for raid4 , the new raidsize will be that limit. If the largest RAID group is below the default value for raid4 , the new raidsize will be that default value. If raidsize is already below the default value for raid4 , it will be reduced by 1.
resyncsnaptime number
This option is used to set the mirror resynchronization snapshot frequency (in minutes). The default value is 60 minutes.
root
If this option is set on a traditional volume, then the effect is identical as that defined in vol man page. Otherwise, if this option is set on an aggregate capable of containing flexible volumes, then that aggregate is marked as being the one that will also contains the root flexible volume on the next reboot. This option can be used on only one aggregate or traditional volume at any given time. The existing root aggregate or traditional volume will become a non-root entity after the reboot.
Until the system is rebooted, the original aggregate and/or traditional volume will continue to show root as one of its options, and the new root aggregate or traditional volume will show diskroot as an option. In general, the aggregate that has the diskroot option is the one that will contain the root flexible volume following the next reboot.
The only way to remove the root status of an aggregate or traditional volume is to set the root option on another aggregate or traditional volume.
snaplock_compliance
This read only option indicates that the aggregate is a SnapLock Compliance aggregate. Aggregates can only be designated SnapLock Compliance aggregates at creation time.
snaplock_enterprise
This read only option indicates that the aggregate is a SnapLock Enterprise aggregate. Aggregates can only be designated SnapLock Enterprise aggregates at creation time.
snapmirrored off
If SnapMirror is enabled for a traditional volume (SnapMirror is not supported for aggregates that contain flexible volumes), the filer automatically sets this option to on . Set this option to off if SnapMirror is no longer to be used to update the traditional volume mirror. After setting this option to off , the mirror becomes a regular writable traditional volume. This option can only be set to off ; only the filer can change the value of this option from off to on .
snapshot_autodelete on | off
This option is used to set whether snapshot are automatically deleted in the aggr. If set to on then snapshots may be deleted in the aggr to recover storage as necessary. If set to off then snapshots in the aggr are not automatically deleted to recover storage. Note that snapshots may still be deleted for other reasons, such as maintaining the snapshot schedule for the aggr, or deleting snapshots that are associated with specific operations that no longer need the snapshot. To allow snapshots to be deleted in a timely manner the number of aggr snapshots is limited when snapshot_autodelete is enabled. Because of this, if there are too many snapshots in an aggr then some snapshots must be deleted before the snapshot_autodelete option can be enabled.
aggr rename aggrname newname
Renames the aggregate named aggrname to newname . If this aggregate is embedded in a traditional volume, then that volume's name is also changed.
aggr restrict aggrname
[ -t cifsdelaytime ]
Put the aggregate named aggrname in restricted state, starting from either online or offline state. The command takes effect before returning.
If the aggregate contains any flexible volumes, the operation is aborted unless the filer is in maintenance mode.
If the aggregate is embedded in a traditional volume that has CIFS shares, users should be warned before restricting the aggregate (and hence the entire traditional volume). Use the -t switch for this. The cifsdelaytime argument specifies the number of minutes to delay before taking the embedded aggregate offline, during which time CIFS users of the traditional volume are warned of the pending loss of service. A time of 0 means take the aggregate offline immediately with no warnings given. CIFS users can lose data if they are not given a chance to terminate applications gracefully.
aggr scrub resume [ aggrname | plexname | groupname ]
Resumes parity scrubbing on the named aggregate, plex, or group. If no name is given, resume all RAID groups currently undergoing a parity scrubbing that has been suspended.
aggr scrub start [ aggrname | plexname | groupname ]
Starts parity scrubbing on the named online aggregate. Parity scrubbing compares the data disks to the parity disk(s) in their RAID group, correcting the parity disk's contents as necessary. If no name is given, parity scrubbing is started on all online aggregates. If an aggregate name is given, scrubbing is started on all RAID groups contained in the aggregate. If a plex name is given, scrubbing is started on all RAID groups contained in the plex.
aggr scrub status [ aggrname | plexname | groupname ] [ -v ]
Prints the status of parity scrubbing on the named aggregate, plex, or group; all RAID groups currently undergoing parity scrubbing if no name is given. The status includes a percent-complete, and the scrub's suspended status.
The -v flag displays the date and time at which the last full scrub completed along with the current status on the named aggregate, plex, or group; all RAID groups if no name is given.
aggr scrub stop [ aggrname | plexname | groupname ]
Stops parity scrubbing on the named aggregate, plex, or group; if no name is given, on all RAID groups currently undergoing a parity scrubbing.
aggr scrub suspend [ aggrname | plexname | groupname ]
Suspends parity scrubbing on the named aggregate, plex, or group; if no name is given, on all RAID groups currently undergoing parity scrubbing.
aggr show_space [ -h | -k | -m | -g | -t | -b ] < aggrname >
Displays the space usage in an aggregate. Unlike df, this command shows the space usage for each flexible volume within an aggregate If aggrname is specified, aggr show_space only runs on the corresponding aggregate, otherwise it reports space usage on all the aggregates.
All sizes are reported in 1024-byte blocks, unless otherwise requested by one of the -h , -k , -m , -g , or -t options. The -k, -m, -g, and -t options scale each size-related field of the output to be expressed in kilobytes, megabytes, gigabytes, or terabytes respectively.
The following terminology is used by the command in reporting space.
Total space This is the amount of total disk space that the aggregate has. WAFL reserve WAFL reserves a percentage of the total total disk space for aggregate level metadata. The space used for maintaining the volumes in the aggregate comes out of the WAFL reserve. Snap reserve Snap reserve is the amount of space reserved for aggregate snapshots. Usable space This is the total amount of space that is available to the aggregate for provisioning. This is computed as Usable space = Total space – WAFL reserve – Snap reserve df displays this as the 'total' space. BSR NVLOG This is valid for Synchronous SnapMirror destinations only. This is the amount of space used in the aggregate on the destination filer to store data sent from the source filer(s) before sending it to disk. Allocated This is the sum of the space reserved for the volume and the space used by non reserved data. For volume guaranteed volumes, this is at least the size of the volume since no data is unreserved. For volumes with space guarantee of none, this value is the same as the 'Used' space (explained below) since no unused space is reserved. The Allocated space value shows the amount of space that the volume is taking from the aggregate. This value can be greater than the size of the volume because it also includes the metadata required to maintain the volume. Used This is the amount of space that is taking up disk blocks. This value is not the same as the 'used' space displayed by the df command. The Used space in this case includes the metadata required to maintain the flexible volume. Avail Total amount of free space in the aggregate. This is the same as the avail space reported by df.
aggr split plexname aggrname [
-r oldvol newvol ] [
-r ... ]
[
-s suffix ]
Removes plexname from a mirrored aggregate and creates a new unmirrored aggregate named aggrname that contains the plex. The original mirrored aggregate becomes unmirrored. The plex to be split from the original aggregate must be functional (not partial), but it could be inactive, resyncing, or outof-date. Aggr split can therefore be used to gain access to a plex that is not up to date with respect to its partner plex, if its partner plex is currently failed.
If the aggregate in which plexname resides is embedded in a traditional volume, aggr split behaves identically to vol split . The new aggregate is embedded in a new traditional volume of the same name.
If the aggregate in which plexname resides contains exactly one flexible volume, aggr split will by default rename the flexible volume image in the split-off plex to be the same as the new aggregate.
If the aggregate in which plexname resides contains more than one flexible volume, it is necessary to specify how to name the volumes in the new aggregate resulting from the split. The -r option can be used repeatedly to give each flexible volume in the resulting aggregate a new name. In addition, the -s option can be used to specify a suffix that is added to the end of all flexible volume names not covered by a -r .
If the original aggregate is restricted at the time of the split, the resulting aggregate will also be restricted. If the restricted aggregate is hosting flexible volumes, they are not renamed at the time of the split. Flexible volumes will be renamed later, when the name conflict is detected while bringing an aggregate online. Flexible volumes in the aggregate that is brought online first keep their names. That aggregate can be either the original aggregate, or the aggregate resulting from the split. When the other aggregate is brought online later, flexible volumes in that aggregate will be renamed.
If the plex of an aggregate embedded within a traditional volume is offline at the time of the split, the resulting aggregate will be offline. When splitting a plex from an aggregate that hosts flexible volumes, if that plex is offline, but the aggregate is online, the resulting aggregate will come online, and its flexible volumes will be renamed. It is not allowed to split a plex from an offline aggregate.
A split mirror can be joined back together via the -v option to aggr mirror .
aggr status [ aggrname ]
[ -r | -v | -d | -c | -b | -s | -f | -i ]
Displays the status of one or all aggregates on the filer. If aggrname is used, the status of the specified aggregate is printed; otherwise the status of all aggregates in the filer are printed. By default, it prints a one-line synopsis of the aggregate which includes the aggregate name, whether it contains a single traditional volume or some number of flexible volumes , if it is online or offline, other states (for example, partial , degraded , wafl inconsistent , and so on) and peraggregate options. Per-aggregate options are displayed only if the options have been changed from the system default values by using the aggr options command, or by the vol options command if the aggregate is embedded in a traditional volume. If the wafl inconsistent state is displayed, please contact Customer Support.
The -v flag shows the on/off state of all peraggregate options and displays information about each volume, plex and RAID group contained in the aggregate.
The -r flag displays a list of the RAID information for that aggregate. If no aggrname is specified, it prints RAID information about all aggregates, information about file system disks, spare disks, and failed disks. For more information about failed disks, see the -f switch description below.
The -d flag displays information about the disks in the specified aggregate. The types of disk information are the same as those from the sysconfig -d command.
The -c flag displays the upgrade status of the Block Checksums data integrity protection feature.
The -b is used to get the size of source and destination aggregates for use with aggr copy . The output contains the storage in the aggregate and the possibly smaller size of the aggregate. The aggregate copy command uses these numbers to determine if the source and destination aggregate sizes are compatible. The size of the source aggregate must be equal or smaller than the size of the destination aggregate.
The -s flag displays a listing of the spare disks on the filer.
The -f flag displays a list of the failed disks on the filer. The command output includes the disk failure reason which can be any of following:
The -i flag displays a list of the flexible volumes contained in an aggregate.
unknown Failure reason unknown. failed Data ONTAP failed disk due to a fatal disk error. admin failed User issued a 'disk fail' command for this disk. labeled broken Disk was failed under Data ONTAP 6.1.X or an earlier version. init failed Disk initialization sequence failed. admin removed User issued a 'disk remove' command for this disk. not responding Disk not responding to requests. pulled Disk was physically pulled, or no data path exists on which to access the disk. bypassed Disk was bypassed by ESH.
aggr undestroy [
-n ] <
aggrname >
Undestroy a partially intact or previously destroyed aggregate or traditional volume. The command prints a list of candidate aggregates and traditional volumes matching the given name, which can be potentially undestroyed.
The -n option prints the list of disks contained by the aggregate or by the traditional volume, which can be potentially undestroyed. This option can be used to display the result of command execution, without actually making any changes.
aggr verify resume [ aggrname ]
Resumes RAID mirror verification on the named aggregate; if no aggregate name is given, on all aggregates currently undergoing a RAID mirror verification that has been suspended.
aggr verify start [ aggrname ] [ -f plexnumber ]
Starts RAID mirror verification on the named online mirrored aggregate. If no name is given, then RAID mirror verification is started on all online mirrored aggregates. Verification compares the data in both plexes of a mirrored aggregate. In the default case, all blocks that differ are logged, but no changes are made. If the -f flag is given, the plex specified is fixed to match the other plex when mismatches are found. A name must be specified with the -f plexnumber option.
aggr verify stop [ aggrname ]
Stops RAID mirror verification on the named aggregate; if no aggregate name is given, on all aggregates currently undergoing a RAID mirror verification.
aggr verify status [ aggrname ]
Prints the status of RAID mirror verification on the named aggregate; on all aggregates currently undergoing RAID mirror verification if no aggregate name is given. The status includes a percent-complete, and the verification's suspended status.
aggr verify suspend [ aggrname ]
Suspends RAID mirror verification on the named aggregate; if no aggregate name is given, on all aggregates currently undergoing RAID mirror verification.
Aggregates on different filers in a cluster can have the same name. For example, both filers in a cluster can have an aggregate named
aggr0 .
However, having unique aggregate names in a cluster makes it easier to migrate aggregates between the filers in the cluster.
aggr create aggr1 -r 10 20 Creates an aggregate named aggr1 with 20 disks. The RAID groups in this aggregate can contain up to 10 disks, so this new aggregate has two RAID groups. The filer adds the current spare disks to the new aggregate, starting with the smallest disk.
aggr create aggr1 20@9
Creates an aggregate named aggr1 with 20 9-GB disks. Because no RAID group size is specified, the default size (8 disks) is used. The newly-created aggregate contains two RAID groups with 8 disks and a third group with four disks.
aggr create aggr1 -d 8a.1 8a.2 8a.3
Creates an aggregate named aggr1 with the specified three disks.
aggr create aggr1 10
aggr options aggr1 raidsize 5
The first command creates an aggregate named aggr1 with 10 disks which belong to one RAID group. The second command specifies that if any disks are subsequently added to this aggregate, they will not cause any current RAID group to have more than five disks. Each existing RAID group will continue to have 10 disks and no more disks will be added to that RAID group. When new RAID groups are created, they will have a maximum size of five disks.
aggr show_space -h ag1
Displays the space usage of the aggregate `ag1′ and scales the unit of space according to the size.

aggr status aggr1 -r
Displays the RAID information about aggregate aggr1 . In the following example, we see that aggr1 is a RAID-DP aggregate protected by block checksums. It is online, and all disks are operating normally. The aggregate contains four disks -two data disks, one parity disk, and one doubleparity disk. Two disks are located on adapter 0b, and two on adapter 1b. The disk shelf and bay numbers for each disk are indicated. All four disks are 10, 000 RPM FibreChannel disks attached via disk channel A. The disk "Pool" attribute is displayed only if SyncMirror is licensed, which is not the case here (if SyncMirror were licensed, Pool would be either 0 or 1). The amount of disk space that is used by Data ONTAP (“Used”) and is available on the disk (“Phys”) is displayed in the rightmost columns.
