Removal and replacement procedures 34
o
Find a server that has enough empty drive bays to accommodate all the drives from the failed
server and that meets all the other requirements for drive and array migration.
2.
Power down the failed server (" Power down the server blade " on page 24 ). If any data is stored in
the cache module, a green LED on the module flashes every 2 seconds.
CAUTION: Do not detach the cable that connects the battery pack to the cache module.
Detaching the cable causes any unsaved data in the cache module to be lost.
3.
Transfer the hard drives from the failed server to the recovery server station.
4.
Perform one of the following:
o
If the array controller has failed, remove the cache module (on page 31 ) and battery pack
(" Cache module battery pack " on page 32 ) from the failed array controller, and install the cache
module and battery pack on an array controller in the recovery server.
o
If the server has failed, remove the controller, cache module (on page 31 ), and battery pack
(" Cache module battery pack " on page 32 ) from the failed server, and install the controller,
cache module, and battery pack in the recovery server.
5.
Power up the recovery server. A 1759 POST message is displayed, stating that valid data was
flushed from the cache. This data is now stored on the drives in the recovery server. You can now
transfer the drives (and controller, if one was used) to another server.
