Nondisruptive Service and Upgrades

About the HP SureStore E Disk Array XP512 and XP48
Monitoring software detects failed disk drives or internal hardware and
notifies the HP Stress Free Central support center automatically so an HP
service representative can replace the faulty hardware. There is no need to
be concerned with user serviceable components. Only an HP Service
Representative should open the cabinets.
All hardware subassemblies can be removed, serviced, repaired, or
replaced nondisruptively during disk array operation. All microcode
upgrades can be performed during normal disk array operations, using your
disk array's built-in service processor (SVP) or the facilities of the host.
Alternate paths can be set by host failover software or alternate Fibre
Channel paths.
