Determining drive and RAID group information for an aggregate

Some aggregate administration tasks require that you know what types of drives compose the aggregate, their size, checksum, and status, whether they are shared with other aggregates, and the size and composition of the RAID groups.

Step

  1. Show the drives for the aggregate, by RAID group: storage aggregate show-status aggr_name
    The drives are displayed for each RAID group in the aggregate.

    You can see the RAID type of the drive (data, parity, dparity) in the Position column. If the Position column displays shared, then the drive is shared: if it is an HDD, it is a partitioned disk; if it is an SSD, it is part of a storage pool.

Example: A Flash Pool aggregate using an SSD storage pool and data partitions

cluster1::> storage aggregate show-status nodeA_fp_1

Owner Node: cluster1-a
 Aggregate: nodeA_fp_1 (online, mixed_raid_type, hybrid) (block checksums)
  Plex: /nodeA_fp_1/plex0 (online, normal, active, pool0)
   RAID Group /nodeA_fp_1/plex0/rg0 (normal, block checksums, raid_dp)

   RAID Group /nodeA_flashpool_1/plex0/rg1 (normal, block checksums, raid4) (Storage Pool: SmallSP)
