Removal and replacement procedures 50
o
Find a workstation blade that has enough empty drive bays to accommodate all the drives from the
failed workstation blade and that meets all the other requirements for drive and array migration.
2. Power down the failed workstation blade. 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 workstation blade to the recovery workstation 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
47) and battery pack ("Removing the battery pack" on page 48) from the failed array controller,
and install the cache module and battery pack on an array controller in the recovery workstation
blade.
o If the workstation blade has failed, remove the controller, cache module ("Removing the cache
module" on page 47), and battery pack ("Removing the battery pack" on page 48) from the failed
workstation blade, and install the controller, cache module, and battery pack in the recovery
workstation blade.
5. Power up the recovery workstation blade. 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 workstation blade. You
can now transfer the drives (and controller, if one was used) to another workstation blade.
