• To check consistency of virtual disks (not supported on RAID0):
racadm storage ccheck:<vdisk fqdd>
To cancel the consistency check:
racadm storage cancelcheck: <vdisks fqdd>
• To encrypt virtual disks:
racadm storage encryptvd:<VD FQDD>
• To assign or unassign dedicated hot spares:

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 FQDD> -
vd <VirtualDisk FQDD>
A virtual disk can be configured as a boot
device using this feature. This enables fault
tolerance when a VD with redundancy is
selected as the boot device, and also has the
operating system installed on it.
