Maintenance and Service Guide
Field replacement strategy
HP-authorized service providers troubleshoot HSG60 and HSG80 subsystem
problems to the field replaceable unit (FRU) and replace the defective unit.
Replacement procedures for subsystem FRUs addressed in this guide include
HSG60 and HSG80 array controllers, cache modules, DIMMs, ECBs, and GLMs.
One way to replace these components on running subsystems is by using the Field
Replacement Utility (FRUTIL).
Note: HP recommends that you perform shutdown FRU replacement procedures, if
possible.
Note: If you are using ACS V8.8P with the HP StorageWorks Data Replication
Manager (DRM) application,
FRUTIL cannot be run in remote copy set environments on
the target side specifically if I/O is in progress. If the host load is stopped, you can run
FRUTIL on the initiator or target. If the host load is not quiesced and FRUTIL is run while
remote copy I/O is running, the normalization process is reset.
