Changing The Virtual Disk Cache Settings
You can specify the cache memory settings for a single virtual disk or for multiple virtual disks in a storage
array.
Guidelines to change cache settings for a virtual disk:
• After opening the Change Cache Settings dialog, the system may display a window indicating 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 has been removed, or if a mismatch in cache
sizes has been detected by the RAID controller module. After the condition has 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 appear 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.
To change the virtual disk cache settings:
1. In the AMW, select the Storage & Copy Services tab and select a virtual disk.
2. In the menu bar, select Storage → Virtual Disk → Change → Cache Settings.
The Change Cache Settings window is displayed.
3. Select one or more virtual disks.
To select nonadjacent virtual disks, press <Ctrl> click. To select adjacent virtual disks, press <Shift>
click. To select all of the available virtual disks, select Select All.
