Reference Guide

For more information about the controller-specific diskcache, read, write, and cache policy,
see the Dell OpenManage Online Help . For information on specifying 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)
• [diskcachepolicy=<enabled|disabled>] parameter (optional)
Example to Change the read policy of virtual disk 4 on controller 1 to no-read-ahead.
Example
omconfig storage vdisk action=changepolicy controller=1
vdisk=4 readpolicy=nra
Omconfig Replace Member Virtual Disk
Description Replaces the member of a given virtual disk with the destination disk.
Syntax
omconfig storage vdisk action=replacememberdisk controller=id
vdisk=id source=<PDISKID> destination=<PDISKID>, where id is the
controller ID and virtual disk ID as reported by the omreport command. The < PDISK >
variable specifies the physical disk.
NOTE: 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.
Example to Replace physical disk 3 on connector 0 of controller 1 of virtual disk 4 with physical disk 5.
On a Serial Attached SCSI (SAS) controller, the physical disk resides in enclosure 2.
Example for SCSI, SATA,
and ATA Ccntrollers
omconfig storage vdisk action=replacememberdisk controller=1
vdisk=4 source=0:3 destination=0:5
Example for SAS
controllers
omconfig storage vdisk action=replacememberdisk controller=1
vdisk=4 source=0:2:3 destination=0:2:5
Omconfig Rename Virtual Disk
Description Renames a virtual disk.
Syntax
omconfig storage vdisk 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.
NOTE: 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.
Example to Rename virtual disk 4 on controller 1 to vd4.
Example
omconfig storage vdisk action=rename controller=1 vdisk=4
name=vd4
Omconfig Enable Fluid Cache on Virtual Disk
