Problem
You are using ACU to expand
capacity.
ICL has failed.
Mismatched firmware on the
array controllers.
Failover may have occurred.
Cache modules on the array
controllers do not match.
GBIC-SW laser has malfunctioned.
Possible Cause Action
The firmware will automatically
put the RA4000 in nonredundant
mode during capacity expansion.
This is normal behavior.
Check Windows NT Event Log to
determine if the ICL (interconnect
link) to has failed.
1. Check to make sure the
firmware version levels
match.
2. If they do not match, use
Options ROMPaq to update
the firmware.
Check to see if a failover has
occurred. It is normal behavior for
a drive rebuild to restart if a
failover has occurred.
Obtain and replace cache module
so that cache levels match on
both array controllers.
1. Manually fail over resources.
2. Refer to the Compaq
StorageWorks RAID Array
4000 User Guide's
"Replacing GBICs" chapter
for instructions on replacing
a GBIC-SW.
