Using the Storage Management Service 221
omconfig storage vdisk action=reconfigure
controller=1 vdisk=4 raid=r5 pdisk=
0:2:0,0:2:1,0:2:2,0:2:3
Example Syntax to resize
To increase the size of the virtual disk by 20 percent using the available free
space, use RAID-5 and physical disks 0 through 3 on connector 0 of controller
1. On a SAS controller, the physical disks reside in enclosure 2.
In this example, type:
omconfig storage vdisk action=reconfigure
controller=1 vdisk=4 raid=r5 pdisk=
0:2:0,0:2:1,0:2:2,0:2:3 vdcapacityexpansion=yes
sizeinpercent=20
NOTE: vdcapacityexpansion parameter is supported only on PERC H700 and PERC
H800 controllers. If you set vdcapacityexpansion=yes, you should specify
sizeinpercent. If you do not set vdcapacityexpansion, you should specify size.
omconfig Change Virtual Disk Policy
Use the following omconfig command syntax to change a virtual disk’s read,
write, or cache policy.
Complete Syntax
omconfig storage vdisk action=changepolicy
controller=id vdisk=id [diskcachepolicy=
<enabled|disabled> | readpolicy=<ra| nra| ara|
rc|nrc> | writepolicy=<wb| wt| wc| nwc> | fwb>
cachepolicy=<d | c>]
where id is the controller ID and virtual disk ID as reported by the omreport
command. To obtain these values, type omreport storage controller to display
the controller IDs and then type omreport storage vdisk controller=ID to
display the IDs for the virtual disks attached to the controller.
See the Dell OpenManage Online Help for more information about the
controller-specific diskcache, read, write, and cache policy. For information
on specifying these parameters using the omconfig command, see the
following:
