See "Parameter Specification for Create and Reconfigure Virtual Disk" for information on specifying the parameters. See "pdisk=<PDISKID> Parameter" and
"Multiple Targets" for more information on specifying physical disks.

Example Syntax

For example, you want to reconfigure virtual disk 4 to a size of 800MB. You will 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.

Example for SCSI, SATA, and ATA Controllers:

In this example, you would enter:

omconfig storage vdisk action=reconfigure controller= 1 vdisk=4 raid=r5 size=800m pdisk=0:0,0:1,0:2,0:3

See "pdisk=<PDISKID> Parameter on SCSI, SATA, and ATA Controllers" and "Multiple Targets" for more information on physical disk specification. See "RAID
Controller Technology: SCSI, SATA, ATA, and SAS" to identify which technology a controller uses.

Example for SAS Controllers:

In this example, you would enter:

omconfig storage vdisk action=reconfigure controller= 1 vdisk=4 raid=r5 pdisk=0:2:0,0:2:1,0:2:2,0:2:3


See "pdisk=<PDISKID> Parameter on SAS Controllers" and "Multiple Targets" for more information on physical disk specification. See "SAS RAID Controllers" to
identify which controllers use SAS technology.

omconfig Change Virtual Disk Policy

Does my controller support this feature? See "Supported Features."

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 [readpolicy=<ra | nra | ara | rc | nrc> | writepolicy=<wb | wt| wc | nwc |
fwb> | cachepolicy=<d | c> diskcachepolicy=<d | e>]

where id is the controller ID and virtual disk ID as reported by the omreport command. To obtain these values, you would enter omreport storage controller to
display the controller IDs and then enter omreport storage vdisk controller=ID to display the IDs for the virtual disks attached to the controller.

For information on the controller-specific read, write, cache policy, and disk cache policy, see "RAID Controller Read, Write, Cache, and Disk Cache Policy." For
NOTE: When using a SAS controller, the size parameter is not required.
