Disks with different capacities are added to the same RAID group
Applies to
- ONTAP 9
- FAS/AFF Systems
Issue
- From the
sysconfig -aoutput, it is seen that different capacity drives are installed in the two shelves:
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)
- The disks with different capacities are mixed in the same RAID group:
::> 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)
