RAID Configuration Features
Following table lists some of the RAID configuration features which are available in RACADM and WSMan:
CAUTION: Forcing a physical disk to go online or offline may result in data loss.
Table 56. RAID Configuration Features
Feature RACADM Command Description
Force Online
racadm storage
forceonline:<PD FQDD>
A power failure, corrupted data, or some
other reason may lead to a physical disk
going offline. You can use this feature to
force a physical disk back into an online
state when all other options have been
exhausted. Once the command is run,
the controller places the drive back into
online state and restore its membership
within the virtual disk. This happens only
if the controller can read from the drive
and can write into its metadata.
NOTE: Data recovery is only possible if a limited portion of the disk is damaged. Force Online feature cannot fix an already
failed disk.
