Viewing RAID status

About RAID status

You use the aggr status command to check the current RAID status and configuration for your aggregates.

To view RAID status for your aggregates, complete the following step.

Step	Action
1	Enter the following command: *aggr status [aggr_name] -r* aggregate_name is the name of the aggregate whose RAID status you want to view. Note If you omit the name of the aggregate (or the traditional volume), Data ONTAP displays the RAID status of all the aggregates on the storage system.

Step

Action

Enter the following command:

aggr status [aggr_name] -r

aggregate_name is the name of the aggregate whose RAID status you want to view.

Note
If you omit the name of the aggregate (or the traditional volume), Data ONTAP displays the RAID status of all the aggregates on the storage system.

Possible RAID status displayed

The aggr status -r or volume status -r command displays the following possible status conditions that pertain to RAID:

Degraded--The aggregate contains at least one degraded RAID group that is not being reconstructed after single- disk failure.
Double degraded--The aggregate contains at least one RAID group with double-disk failure that is not being reconstructed (this state is possible if RAID-DP protection is enabled for the affected aggregate).
Double reconstruction xx% complete--At least one RAID group in the aggregate is being reconstructed after experiencing a double-disk failure (this state is possible if RAID-DP protection is enabled for the affected aggregate).
Mirrored--The aggregate is mirrored, and all of its RAID groups are functional.
Mirror degraded--The aggregate is mirrored, and one of its plexes is offline or resynchronizing.
Normal--The aggregate is unmirrored, and all of its RAID groups are functional.
Partial--At least one disk was found for the aggregate, but two or more disks are missing.
Reconstruction xx% complete--At least one RAID group in the aggregate is being reconstructed after experiencing a single- disk failure.
Resyncing--The aggregate contains two plexes; one plex is resynchronizing with the aggregate.
