Dell PowerEdge RAID Controller H700: Managing Preserved Cache

8

Place the top edge of the battery over the top edge of the DIMM so that the

arms on the side of the battery fit into their sockets on the DIMM.

See Figure 1-2.

9

Align the keyed edge of the DIMM to the physical divider on the memory

socket to avoid damage to the module.

10

Insert the DIMM in the memory socket. Apply a constant, downward pressure

on both ends or on the middle of the DIMM until the retention clips fall in

the allotted slots on either side of the DIMM. See Figure 1-2.

Managing Preserved Cache

If a virtual disk becomes offline or is deleted because 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.

CAUTION: If there are any foreign configurations, it is strongly advised that you

import the foreign configuration before you discard the preserved cache. Otherwise,

you lose data that belongs to the foreign configuration.
