• Reconnect hdisk0, close the casing, and turn the key to normal mode.
• Power on NodeF then verify that the rootvg logical volumes are no longer
stale (
lsvg -l rootvg
).
6.2.4.2 7135 Disk Failure
Perform the following steps in the event of a disk failure:
Perform the following steps in the event of a disk failure:
• Check, by way of the verification commands, that all the Nodes in the
cluster are up and running.
• Optional: Prune the error log on NodeF (
errclear 0
).
• Monitor cluster logfiles on NodeT if HACMP has been customized to
monitor 7135 disk failures.
• Mark a shared disk failed through smit (
smit raidiant
; RAIDiant Disk
Array Manager -> Change/Show Drive Status -> select the appropriate
hdisk -> select the appropriate physical disk -> F4 to select a Drive
Status of 83 Fail Drive), or if the disk is hot pluggable, remove the disk.

• The amber light on the front of the 7135 comes on, and can also be seen
in SMIT (
smit raidiant
; RAIDiant Disk Array Manager -> List all SCSI
RAID Arrays).
• Verify that all sharedvg file systems and paging spaces are accessible (
df
and
lsps -a
).
• If using RAID5 with Hot Spare, verify that reconstruction has completed to
the Hot Spare, then un-mark or plug the failed disk back in. If using
RAID1, sync the volume group (
