NetApp Aggregate and Volume Status



An aggregate can be in one of the below three states

OnlineRead and write access to volumes is allowed
RestrictedSome operations, such as parity reconstruction are allowed, but data access is not allowed
OfflineNo access to the aggregate is allowed


The aggregate can have a number of different status values


32-bitThis aggregate is a 32-bit aggregate
64-bitThis aggregate is a 64-bit aggregate
aggrThis aggregate is capable of contain FlexVol volumes
copyingThis aggregate is currently the target aggregate of an active copy operation
degradedThis aggregate is contains at least one RAID group with single disk failure that is not being reconstructed
double degradedThis aggregate is contains at least one RAID group with double disk failure that is not being reconstructed (RAID-DP aggregate only)
foreignDisks that the aggregate contains were moved to the current storage system from another storage system
growingDisks are in the process of being added to the aggregate
initializingThe aggregate is in the process of being initialized
invalidThe aggregate contains no volumes and none can be added. Typically this happend only after an aborted "aggr copy" operation
ironingA WAFL consistency check is being performewd on the aggregate
mirror degradedThe aggregate is mirrored and one of its plexes is offline or resynchronizing
mirroredThe aggregate is mirrored
needs checkWAFL consistency check needs to be performed on the aggregate
normalThe aggregate is unmirrored and all of its RAID groups are functional
out-of-dateThe aggregate is mirrored and needs to be resynchronized
partialAt least one disk was found for the aggregate, but two or more disks are missing
raid0The aggrgate consists of RAID 0 (no parity) RAID groups
raid4The agrregate consists of RAID 4 RAID groups
raid_dpThe agrregate consists of RAID-DP RAID groups
reconstructAt least one RAID group in the aggregate is being reconstructed
redirectAggregate reallocation or file reallocation with the "-p" option has been started on the aggregate, read performance will be degraded
resyncingOne of the mirror aggregates plexes is being resynchronized
snapmirrorThe aggregate is a SnapMirror replica of another aggregate (traditional volumes only)
tradThe aggregate is a traditional volume and cannot contain FlexVol volumes.
verifyingA mirror operation is currently running on the aggregate
wafl inconsistentThe aggregate has been marked corrupted; contact techincal support




Volumes:


OnlineRead and write access to this volume is allowed.
RestrictedSome operations, such as parity reconstruction, are allowed, but data access is not allowed.
OfflineNo access to the volume is allowed.


There are number of possible status values for volumes


access deniedThe origin system is not allowing access. (FlexCache volumes
only.)
active redirectThe volume's containing aggregate is undergoing reallocation (with the -p option specified). Read performance may be reduced while the volume is in this state.
connectingThe caching system is trying to connect to the origin system. (FlexCache volumes only.)
copyingThe volume is currently the target of an active vol copy or snapmirror operation.
degradedThe volume's containing aggregate contains at least one degraded RAID group that is not being reconstructed after single disk failure.
double degradedThe volume's containing aggregate contains at least one degraded RAID-DP group that is not being reconstructed after double disk failure.
flexThe volume is a FlexVol volume.
flexcacheThe volume is a FlexCache volume.
foreignDisks used by the volume's containing aggregate were moved to the current storage system from another storage system.
growingDisks are being added to the volume's containing aggregate.
initializingThe volume's containing aggregate is being initialized.
invalidThe volume does not contain a valid file system.
ironingA WAFL consistency check is being performed on the volume's containing aggregate.
lang mismatchThe language setting of the origin volume was changed since the caching volume was created. (FlexCache volumes only.)
mirror degradedThe volume's containing aggregate is mirrored and one of its plexes is offline or resynchronizing.
mirroredThe volume's containing aggregate is mirrored.
needs checkA WAFL consistency check needs to be performed on the volume's containing aggregate.
out-of-dateThe volume's containing aggregate is mirrored and needs to be resynchronized.
partialAt least one disk was found for the volume's containing aggregate, but two or more disks are missing.
raid0The volume's containing aggregate consists of RAID0 (no parity) groups (array LUNs only).
raid4The volume's containing aggregate consists of RAID4 groups.
raid_dpThe volume's containing aggregate consists of RAID-DP groups.
reconstructAt least one RAID group in the volume's containing aggregate is being reconstructed.
redirectThe volume's containing aggregate is undergoing aggregate reallocation or file reallocation with the -p option. Read performance to volumes in the aggregate might be degraded.
rem vol changedThe origin volume was deleted and re-created with the same name. Re-create the FlexCache volume to reenable the FlexCache relationship. (FlexCache volumes only.)
rem vol unavailThe origin volume is offline or has been deleted. (FlexCache volumes only.)
remote nvram errThe origin system is experiencing problems with its NVRAM. (FlexCache volumes only.)
resyncingOne of the plexes of the volume's containing mirrored aggregate is being resynchronized.
snapmirroredThe volume is in a SnapMirror relationship with another volume.
tradThe volume is a traditional volume.
unrecoverableThe volume is a FlexVol volume that has been marked unrecoverable; contact technical support.
unsup remote volThe origin system is running a version of Data ONTAP the does not support FlexCache volumes or is not compatible with the version running on the caching system. (FlexCache volumes only.)
verifyingRAID mirror verification is running on the volume's containing aggregate.
wafl inconsistentThe volume or its containing aggregate has been marked corrupted; contact technical support .
