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.
Force Offline
racadm storage
forceoffline:<PD FQDD>
This feature removes a drive from a
virtual disk configuration so that it
goes offline, resulting in a degraded VD
configuration. It is helpful if a drive is
likely to fail in near future or is reporting
a SMART failure but is still online. It can
be also used if you would like to utilize
a drive which is part of an existing RAID
configuration.
Replace Physical Disk
racadm storage
replacephysicaldisk:<Source
PD FQDD > -dstpd
<Destination PD FQDD>
Allows you to copy data from a physical
disk which is a member of a VD, to
another physical disk. The source disk
should be in online state, while the
destination disk should be in ready state
and of a similar size and type to replace
the source.
Virtual Disk as boot device
racadm storage
setbootvd:<controller
A virtual disk can be configured as
a boot device using this feature. This
enables fault tolerance when a VD with
