Changing the Virtual Disk Cache Settings

You can specify the cache memory settings for a single virtual disk or for

multiple virtual disks on a storage array.
Guidelines to change cache settings for a virtual disk:

• After opening the Change Cache Settings dialog, the system may prompt

you that the RAID controller module has temporarily suspended caching

operations. This action may occur when a new battery is charging, when a

RAID controller module is removed, or if a mismatch in cache sizes is

detected by the RAID controller module. After the condition is cleared,

the cache properties selected in the dialog become active. If the selected

cache properties do not become active, contact your Technical Support

representative.

• If you select more than one virtual disk, the cache settings default to no

settings selected. The current cache settings are displayed only if you select

a single virtual disk.

• If you change the cache settings by using this option, the priority of all of

the virtual disks that you selected is modified.
