53HP StorageWorks HSG60 and HSG80 Controller and HSx80 Cache Module Replacement
Procedures for Array Controller Software V8.7x-x Release Notes
After a SHOW THIS_CONTROLLER or SHOW OTHER_CONTROLLER
command is submitted, the controller displays one or both of the following cache
conditions:
Cache: Cache is GOOD
Mirrored Cache: Cache is FAILED
Note: This condition cannot be resolved with the CLEAR OTHER_CONTROLLER
INVALID_CACHE DESTROY_UNFLUSHED_DATA command.
To resolve the error message, see Table 4 on page 54.
Caution: The resolution for a failed cache error message in Table 4 on
page 54 involves the interruption of service to the customer. Notify your
manager and customers of this situation,
and make sure that the controllers are
not in use
before proceeding to resolve a failed cache condition. Avoiding this
precaution may result in data loss.
■ Event 2: Before Setting the Failover Mode
Before Failover mode has been set and after the replacement controller
restarts following the Port #5 button reset process (see substep 5c through
substep 5f on page 30), the replacement controller CLI message indicates that
the mirrored cache is in a failed condition. When a
SHOW THIS_CONTROLLER command is submitted, the replacement
controller indicates that its mirrored cache is in a Failed state:
Cache: Cache is GOOD
Mirrored Cache: Cache is FAILED
Table 5 on page 56 provides instructions for resolving the above event. If the
failure cannot be cleared using the procedures in Table 5, a defective hardware
component may exist. If this is the case, identify which component is defective,
and replace it.
