ONTAP如何向SyncMirror聚合添加磁盘

适用场景

• ONTAP 9
• SyncMirror

问题解答

ONTAP 会将一半磁盘 添加到原始RAID组、而另一半磁盘将添加到镜像RAID组。

示例：

::> 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.

追加信息

向SyncMirror聚合添加磁盘时、磁盘数必须为偶数。
