Removal and replacement procedures 37
CAUTION:
Before starting this procedure, read the information about protecting against
electrostatic discharge ("
Preventing electrostatic discharge
" on page

).
1.
Perform one of the following:
o
Set up a recovery server blade station using an identical server blade model. Do not install any
internal drives or BBWC in this server blade. (HP recommends this option.)
o
Find a server blade that has enough empty drive bays to accommodate all the drives from the failed
server blade and that meets all the other requirements for drive and array migration.
2.
Power down the failed server blade ("
Power down the server blade
" on page
23
). 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 blade to the recovery server blade station.
4.
Perform one of the following:
o
If the array controller has failed, remove the cache module ("
Removing the cache module
" on page
34
) and battery pack ("
Removing the battery pack or capacitor pack
" on page
35
) from the failed
array controller, and install the cache module and battery pack on an array controller in the
recovery server blade.
o
If the server blade has failed, remove the controller, cache module ("
Removing the cache module
"
on page
34
), and battery pack ("
Removing the battery pack or capacitor pack
" on page
35
) from
the failed server blade, and install the controller, cache module, and battery pack in the recovery
server blade.
5.
Power up the recovery server blade. 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 blade. You can now
transfer the drives (and controller, if one is used) to another server blade.
Recovering data from the flash-backed write cache
If the server blade fails, use the following procedure to recover data temporarily stored in the FBWC.
