Cache Hardware Batteries Missing - HP StorageWorks MSA500 G2 User Manual

Troubleshooting 107
Error 1.1 and 1.2: Only one cache board is in the controller, but the controller
was configured with a second cache board that is missing (dual cache module
configuration).
Error 2.1 and 2.2: A second cache board that contained valid data was removed
from its original controller and added to this controller (dual cache module
configuration).
Error 2.3: A cache board that contained valid data was removed from its original
controller and added to this controller (single cache module configuration).
1. Return all cache boards to their original controllers.
2. Power up the storage systems without allowing any host I/O.
3. Wait for the controller to write cache data to the drives. This can take several
minutes.
4. Power down the storage systems and relocate cache boards, as needed.
