2.
Power down the failed server ("

).
3.
Transfer the drives from the failed server to the recovery server.
4.
Perform one of the following:
o
If the array controller has failed, remove the cache module and capacitor pack from the failed array
controller, and install the cache module and capacitor pack on an identical array controller model
in the recovery server.
o
If the server has failed, remove the controller, cache module, and capacitor pack from the failed
server, and install the controller, cache module, and capacitor pack in the recovery server.
5.
Power up the recovery server. If there was data in the cache at the time of the controller or server failure,
a 1792 POST message appears, 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 is
used) to another server.
If the drives are migrated to different drive positions or there are volumes present in the recovery server,
a 1724 POST message appears, stating that logical drive configuration has been updated
automatically.
System battery
If the server no longer automatically displays the correct date and time, you might have to replace the battery
that provides power to the real-time clock. Under normal use, battery life is 5 to 10 years.
