从 sysconfig -a 输出中可以看出，两个磁盘架上安装了不同容量的驱动器：

00.9 : NETAPP X380_WVAXE10TA07 NA02 9324.2GB 520B/sect (VXXXXXXM) 00.10: NETAPP X380_WVAXE10TA07 NA02 9324.2GB 520B/sect (VXXXXXXN) 00.11: NETAPP X380_WVAXE10TA07 NA02 9324.2GB 520B/sect (VXXXXXXO) 01.0 : NETAPP X336_TTCRE04TA07 NA04 3807.8GB 520B/sect (XXXXXXXXXXXC) 01.1 : NETAPP X336_TTCRE04TA07 NA04 3807.8GB 520B/sect (XXXXXXXXXXXD) 01.2 : NETAPP X336_TTCRE04TA07 NA04 3807.8GB 520B/sect (XXXXXXXXXXXE)

不同容量的磁盘混合在同一个 RAID 组中：

::> system node run -node Node-01 -command sysconfig -r

Aggregate aggr_01 (online, raid_dp, fast zeroed) (block checksums) Plex /aggr_01/plex0 (online, normal, active, pool0) RAID group /aggr_01/plex0/rg0 (normal, block checksums)
