1.3 Commands for Configuring Virtual Disk (Vdisk)
There are set of RACADM commands to create or delete virtual disks, manage virtual disk properties, and
performs operations such as background initialization, consistency check, locate, and reconfiguration. The
createvd command will create virtual disk and the mandatory parameters are controller FQDD, RAID
level, and FQDDs of physical disk drives. Span count, span size, VdName, write protection, read policy, vd
size, and disc cache policy are optional parameters
The command syntax is:
racadm raid createvd:RAID.Integrated.1-1 -rl {r0|r1|r5|r6|r10|r50|r60} [-wp
{wt|wb}] [-rp {nra|ra|ara}][-ss
{1k|2k|4k|8k|16k|32k|64k|128k|256k|512k|1M|2M|4M|8M|16M}] -pdkey:<comma
separated PD FQDD>[-dcp {enabled|disabled|default}] [-name <VD name>] [-size <VD
size>{b|k|m|g|t}]
Key notes while creating a virtual disk are:
 For hybrid RAID levels such as RAID10 and RAID 50 ‘span count’ is a mandatory parameter.
 Span count (-sc) must not be 0 for any of the RAID levels except RAID10.
 After creating a virtual disk, you must create a job and restart the server operating system (OS) to
apply a configurations of a virtual disk.
 To create a virtual disk from a set of physical disk drives, all the physical disk drives must have the
same size, speed, and should be in a ready state.
 Before using a virtual disk, initialize the virtual disks by running the command:
$ racadm raid init:<VD FQDD>.
 A virtual disk can be deleted by running the command:
$ racadm raid deletevd:<VD FQDD>
 A virtual disk can be encrypted for better security by running the command:
$ racadm raid racadm raid encryptvd:<VD FQDD>
For example:
$ racadm raid createvd:RAID.Integrated.1-1 -rl r0 -pdkey:Disk.Bay.3:Enclosure.Internal.0-
1:RAID.Integrated.1-1
RAC1040 : Successfully configured the RAID, and the change is in pending
state. To apply the updated values, create a configuration job, and then
restart the system. To create the commit- and reboot jobs, run the jobqueue
command. For more information about the jobqueue command, see the RACADM Help file.
