Command Line Interface Guide

The omconfig syntax for creating a virtual disk has several parameters. You must specify the following parameters:
• Controller (controller=id)
• RAID level (raid=<c| r0 | r1 | r1c | r5 | r6 | r10 | r50 | r60>
• Size (size=<number | max | min>)>
Physical disk is specified as either:
• For SCSI, SATA, and ATA controllers:
pdisk=connector:enclosureID:targetID
where connector:enclosureID:targetID is the connector number, enclosure number, and slot number.
• For SAS controllers:
pdisk=connector:targetID
where connectorID:targetID is the connector number and the slot number. For example, pdisk=0:2
Storage Management supplies default values for any of the other parameters that you do not specify.
For creating an encrypted virtual disk, specify secureflag=yes. You can create encrypted virtual disks only with
SED drives.
Complete Syntax:
omconfig storage controller action=createvdisk controller=id raid=<c| r0 | r1 |
r1c | r5 | r6 | r10 | r50 | r60>size=<number | max | min> pdisk=<PDISKID>
[stripesize=stripesize=< 2kb| 4kb| 8kb| 16kb| 32kb| 64kb | 128kb>]
[cachepolicy=<d | c>] [diskcachepolicy=<disabled | enabled>][readpolicy=<ra |
nra | ara | rc | nrc>] [writepolicy=<wb| wt| wc| nwc | fwb>] [name=<
string>]
[spanlength=<n>] | [secureflag=yes]
NOTE: If you are configuring RAID for SAS controllers with firmware version 6.1 and later, spanlength is an
optional parameter (default=2).
Spanlength is an even number and is lesser than or equal to half the number of
physical disks specified in size.
Example Syntax:
You can create a RAID-5 virtual disk of 500 MB with a stripe size of 16 KB on a PERC 3/QC controller. The name of the
virtual disk is vd1 and it resides on connector 0 of controller 1. Because the virtual disk is a RAID-5, it requires at least
three physical disks. In this example, you specify four physical disks. These are physical disks 0 through 3. The virtual
disk has read-ahead, write–through caching, and cache I/O policies.
To create a virtual disk:
omconfig storage controller action=createvdisk controller=1 raid=r5 size=500m
pdisk= 0:0,0:1,0:2,0:3 stripesize=16kb cachepolicy=c readpolicy=ra
writepolicy=wt
The only parameters that require specification are for the controller, RAID level, virtual disk size, and physical disk
selection. Storage Management supplies default values for all other unspecified parameters. For more information on
read, write, and cache policies that are supported by the controller, see the Dell OpenManage Online Help .
