Recovering from an unplanned or emergency power
outage
Unplanned power outages occur when the primary building power is lost d ue to
electrical bl
ackouts, thunderstorm activity, or similar occurrences, and input AC power
is not received by the system. The system will maintain its state and recover when
power is restored.
The system ca
che is powered by backup batteries that will m aintain the system state for
up to 36 hours, depending on the selected battery operation mode.
For restart procedures after power is restored to the system, see the following text about
manual and automatic restart of the system. If the length of a power outage exceeds the
cache batter y backup time, contact HP for assistance with recovery.
Manual restart after power is restored

After power is restored to your site and before restoring power to the system, HP

external disk array(s) first and make sure they are operating properly.
For assistance recovering from a power outage, contact your H P support representative.
