NOTE: Importing a broken mirror is the same as importing a foreign conguration. See Importing Or Clearing Foriegn

Congurations Using VD Mgmt Menu. The imported virtual disk is in a degraded state until the missing member is

rebuilt.

Managing preserved cache

If a virtual disk goes oine or is deleted goes of missing physical disks, the controller preserves the dirty cache from the virtual disk. The

preserved dirty cache, known as pinned cache, is preserved until you import the virtual disk or discard the cache.

NOTE: Certain operations, such as creating a new virtual disk, cannot be performed if preserved cache exists. You have to enter

the BIOS Conguration Utility (<Ctrl> <R>) to resolve the situation before you boot to the operating system. Messages are

displayed notifying you that you must enter the BIOS Conguration Utility (<Ctrl> <R>) to discard the preserved cache or

import the virtual disks with the preserved cache.

CAUTION: If there are any foreign congurations, it is strongly advised that you import the foreign conguration before you

discard the preserved cache. Otherwise, you might lose data that belongs with the foreign conguration.

To manage the preserved cache:

1 On the VD Mgmt screen, click on a controller icon.

2 Press <F2> to display the available actions.

3 Select Manage Preserved Cache.

A message is displayed advising you to import the foreign conguration before you discard the preserved cache to avoid losing data

belonging to the foreign conguration. Conrm whether you want to continue. The Manage Preserved Cache screen displays the

aected virtual disks.

4 You can choose to discard the cache on the Manage Preserved Cache screen. If you press Cancel, the process is cancelled and the

Preserved Cache Retained dialog box is displayed.

If you choose to discard the cache, you are prompted to conrm your choice. If you choose to retain the cache, a message is displayed

to notify you that you cannot perform certain operations while the cache exists. Click OK to continue.

Managing dedicated hot spares
