Emergency power-off

Caution
46
Two situations may arise when you need to power down the disk array:
• Emergency power-off
• Planned power-off
In an emergency, it is critical to remove power to the disk array as quickly
as possible.
Performing the emergency power-off procedure 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.Only a qualified HP
support representative can reset the switch and restore power to the disk
array.
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 abnormal loud noise, smell, or smoke coming from the
disk array
