Reference Guide

NOTE: Enabling fluid cache creates a new fluid cache disk. You must use only the new
fluid cache disk for all future data access. Data access to any of the corresponding
virtual disk or caching its partitions may lead to data corruption.
Syntax
omconfig storage vdisk action=enablefluidcache controller=id
vdisk=id devicename=<string> cachepolicy=<wb|wt>, where id is the
controller ID and virtual disk ID as reported by the omreport command and <string> is the
device name of the virtual disk, wb is writeback, and wt is writethrough. To obtain the
values for controller ID and virtual disk ID, 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 Enable fluid cache on virtual disk 4 on controller 1.
Example
omconfig storage vdisk action=enablefluidcache controller=1
vdisk=4 devicename=/dev/sdb cacachepolicy=wb
Omconfig Disable Fluid Cache on Virtual Disk
Description Disables fluid cache for the specified virtual disk.
Syntax
omconfig storage vdisk action=disablefluidcache controller=id
vdisk=id devicename=<string>, where id is the controller ID and virtual disk ID
as reported by the omreportcommand and <string> is the device name of the virtual disk.
To obtain the values for controller ID and virtual disk ID, 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 Disable fluid cache on virtual disk 4 on controller 1.
Example
omconfig storage vdisk action=disablefluidcache controller=1
vdisk=4 devicename=/dev/sdb
Omconfig Reactivate Fluid Cache on Virtual Disk
Description Reactivates the fluid cache for the specified virtual disk.
Syntax
omconfig storage vdisk action=reactivate controller=id
vdisk=id devicename=<string>, where id is the controller ID and virtual disk ID
as reported by the omreportcommand and <string> is the device name of the virtual disk.
To obtain the values for controller ID and virtual disk ID, 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 Reactivate fluid cache on virtual disk 4 on controller 1
Example
omconfig storage vdisk action=reactivate controller= 1
vdisk=4 devicename=/dev/sdb
Omconfig Controller Commands
The following table provides the omconfig command syntax required to execute controller tasks.
CAUTION: The omconfig storage controller action=resetconfig controller=id resets the controller configuration.
Resetting the controller configuration permanently destroys all data on all virtual disks attached to the controller.
System or boot partition residing on these virtual disks is destroyed.
