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.
If this action does not solve the problem, contact HP support.
72 Cache Error Ignore>? <=NO >=YES
Type: User Input
Description: During power up, the controller found data in the cache but could
not flush the data to the drives.
One of two conditions exists:
• The data does not belong to this controller (the cache board was moved from
a different controller).
• The cache data is partial or incomplete (the rest of the data is in another
cache board that was removed from the controller).
This error can occur if cache boards are moved improperly.
Action:
• Select the NO option to halt the controller and solve the problem.
• Select the YES option to erase the cache data. Operation of the controller
continues normally.
