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.
