Nondisruptive Service And Upgrades - HP StorageWorks XP1024 - Disk Array Owner's Manual

Nondisruptive service and upgrades

Overview
Monitoring software detects internal hardware component problems and
notifies the HP Storage Technology Center automatically. At the support
center, the problem is verified and the appropriate maintenance activity is
executed by an HP service representative. The are no user serviceable
components. Only an HP service representative should open the cabinets.
All hardware subassemblies can be removed, serviced, repaired, or
replaced non-disruptively during disk array operation. All microcode
upgrades can be performed during normal disk array operations (provided
array connectivity infrastructure requirements are satisfied), using your
disk array's built-in service processor (SVP). Alternate paths can be set by
host failover software and/or alternate Fibre Channel paths.
