omconfig storage vdisk action=changepolicy controller=id vdisk=id [readpolicy=<ra | nra | ara | rc | nrc> | writepolicy=<wb | wt| wc | nwc |


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
information on how to specify these parameters using the omconfig command, see the following:

action=rename controller=id vdisk=id name=<string>

where id is the controller ID and virtual disk ID as reported by the omreport command and <string> is the new name for the virtual disk. To obtain the values
for controller ID and virtual disk ID, 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.

Example Syntax

For example, to rename virtual disk 4 on controller 1 to vd4, you would enter:
