Users Guide

￭ Disabled — Indicates that the disk’s write cache is disabled. This decreases performance and the probability of
data loss.
● Edit Disk Capacity — You can add the physical disks to the selected virtual disk in this window. This window also
shows the current capacity and new capacity of the virtual disk after adding the physical disks.
● RAID Level Migration — Displays the Disk Name, Current RAID Level, and size of the virtual disk. Allows you to select a
New RAID Level. User may have to add additional drives to existing Virtual disks to migrate to new raid level. This feature
is not applicable on RAID 10, 50 and 60.
● Initialize: Fast — Updates the metadata on the physical disks so that all the disk space is available for future write
operations. The initialize option can be completed quickly because existing information on the physical disks is not erased,
although future write operations overwrites any information that remains on the physical disks.
● Initialize: Full — All existing data and file systems are erased.
NOTE: The Initialize: Full option is not applicable for PERC H330 controllers.
● Check Consistency — To check the consistency of a virtual disk, select Check Consistency from the corresponding
drop-down menu.
NOTE: Consistency check is not supported on drives set up in RAID0 mode.
For more information about these options, see the iDRAC Online Help.

Time to apply the changes at a particular time, and Discard All Pending to discard the changes.
Based on the selected operation mode, the settings are applied.
Managing virtual disks using RACADM
Use the following commands to manage virtual disks:
● To delete virtual disk:
racadm storage deletevd:<VD FQDD>
● To initialize virtual disk:
racadm storage init:<VD FQDD> -speed {fast|full}
● 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:
racadm storage hotspare:<Physical Disk FQDD> -assign <option> -type dhs -vdkey: <FQDD
of VD>
<option>=yes
Assign hot spare
<Option>=no
Unassign hot spare
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.
