Note: Storage complex repair actions must always be managed from the management console. To replace any FRUs identified in this procedure, use Storage Facility Management > storage facility > Exchange Parts. If the FRUs are listed in this or another Serviceable Event, select them from there.
Important: All storage facility repair activity should be started from Start here. If you have not started from that procedure, go there now and start from the section Analyze and repair problems. If you did start from that section and the analysis procedures produced an SRN, follow the steps below.
