Configuration: Disk Groups and Virtual Disks

To change the virtual disk modification priority:

1 In the AMW, select the Logical tab.
2 Select a virtual disk.
3 In the toolbar, select Virtual Disk Change Modification Priority.

The 

Change Modification Priority window is displayed.

4 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, 

click 

Select All. Move the Select modification priority slider bar to the 

desired priority.

5 Click OK.

A message prompts you to confirm the change in the virtual disk 

modification priority.

6 Click Yes.
7 Click OK.

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.
