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 might 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 Logical tab and select a virtual disk
2 In the toolbar, select Virtual Disk  Change  Cache Settings .
