Powering Down The Disk Array; Emergency Power Off; Planned Power Off - HP StorageWorks XP10000 Owner's Manual

Powering down the disk array

Two situations may arise when you need to power down the disk array:
•

Emergency power off

•

Planned power off

For instructions in each of these situations, see the following procedures.
Emergency power off
The XP10000 disk array does not have an emergency power off switch. In an
emergency when it is crucial to power off the disk array immediately for safety reasons,
remove power at the AC branch circuit breakers in your facility that supply power to the
disk array. Take care when placing these breakers that they are clearly marked and
easily accessible.
CAUTION:
Performing an emergency power off immediately shuts down the disk array, neglecting
the array's normal power off sequence. Jobs in process are aborted and their integrity
after recovery is not guaranteed. Use this power off method only in an emergency.
Afterwards, only a qualified HP support representative is allowed to restore power to
the disk array. Call your HP support representative immediately.
Emergency situations in which you should consider performing the emergency power
off procedure are:
• A physical location catastrophe such as a flood, hurricane, tornado, or
earthquake
• Any circumstance that presents the threat of injury or death to a person
• You detect any smoke, abnormal loud noise, or smell coming from the disk array.
Planned power off
Occasionally, you may need to plan a site power outage, such as during alterations
to the data center, inspections, or work by the electric company. If a scheduled power
outage will affect the disk array, contact your HP support representative to schedule a
planned power off.
CAUTION:
Only a trained HP support representative can shut down and power off the disk array.
Do not attempt to power down the disk array other than during an emergency.
