ONTAP によってディスクの半分が元のRAIDグループに追加され、残りの半分が ミラーRAIDグループに追加されます。

例:

::> storage aggregate add-disks -aggregate aggr1 -diskcount 6 -raidgroup rg0

Disks would be added to aggregate "aggr1" on node "node-1" in the following manner:

First Plex

  RAID Group rg0, 8 disks (block checksum, raid_dp)
                            Usable Physical
   Position   Disk            Type       Size    Size
   ---------- ------------------------- ---------- -------- --------
   data     1.11.8           SAS      836.9GB  838.4GB
   data     1.11.9           SAS      836.9GB  838.4GB
   data     1.11.10           SAS      836.9GB  838.4GB

Second Plex

  RAID Group rg0, 3 disks (block checksum, raid_dp)
                            Usable Physical
   Position   Disk            Type       Size    Size
   ---------- ------------------------- ---------- -------- --------
   data     1.21.11           SAS      836.9GB  838.4GB
   data     1.21.12           SAS      836.9GB  838.4GB
   data     1.21.13           SAS      836.9GB  838.4GB

Aggregate capacity available for volume use would be increased by 2.10TB.

追加情報
