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
[readpolicy=<ra| nra| ara| rc| nrc> | writepolicy=<wb| wt| wc| nwc> |
cachepolicy=<d | c>]
where id is the controller ID and virtual disk ID as reported by the omreport command. To obtain these
values, 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, and cache policy, see the online help. For
information on how to specify these parameters using the omconfig command, see the following:
• [readpolicy=<ra| nra| ara| rc| nrc>] Parameter (Optional)
• [writepolicy=<wb| wt| wc| nwc | fwb>] Parameter (Optional)
• [cachepolicy=<d | c>] Parameter (Optional)
Example Syntax
For example, to change the read policy of virtual disk 4 on controller 1 to no-read-ahead, enter:
omconfig storage vdisk action=changepolicy controller=1 vdisk=4
readpolicy=nra
omconfig Rename Virtual Disk
Use the following omconfig command syntax to rename a virtual disk.
NOTE: On a CERC SATA 1.5/2s controller, you cannot change the default name of a virtual disk.
Complete Syntax
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, 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, enter:
omconfig storage vdisk action=rename controller=1 vdisk=4 name=vd4
