HP StorageWorks XP12000 Disk Array owner's guide (AE002-96029, October 2006)

Nondisruptive service and upgrades
Without d isrupting normal disk array operations (if alternate pathing is used), an HP
support representative can:
• Remove, serv
ice, repair, or replace hardware subassemblies
• Use the built-in service pro cessor (SVP) to upgrade microcode
Alternate paths can be established using host failover software, alternate Fibre Channel
paths, o r both.
CAUTION:
The disk arr
ay has no user-serviceable components. The SVP does not include a
keyboard or monitor and is not a customer-accessible component. Only an HP support
representative should open the cabinets.
HP StorageWorks Continuous Track XP monitoring software d etects internal hardware
component problems and automatically reports them to the HP Storage Te chnology
Center (STC) before they a re noticed by operators and users. An HP suppor t
representative can then verify the problem and perform the appropriate maintenance
activity, with no interruption to applications or hosts. For more information on Continuous
Track XP , see HP StorageWorks Continuous Track X P.
