Recovering From An Unplanned Power Outage; Manual Restart Of The Disk Array After Power Is Restored; To Restart The Disk Array Manually - HP StorageWorks XP10000 Owner's Manual

Recovering from an unplanned power outage

Unplanned power outages occur when the primary building power is lost due to
electrical blackouts, thunderstorm activity, or similar occurrences, and input AC power
is not received by the disk array. The disk array will maintain its state and recover
when power is restored.
The disk array cache is powered by backup batteries that will maintain the array state
for up to 36 hours, depending on the selected battery operation mode.
For restart procedures after power is restored to the disk array, see the following text
about manual and automatic restart of the array.

Manual restart of the disk array after power is restored

CAUTION:
After power is restored to your site and before restoring power to the disk array, HP
recommends that you have an electrician verify the power to ensure that all phases are
restored and input power to the disk is stable.
For assistance recovering from a power outage, contact your HP support representative.

To restart the disk array manually:

1.
On the disk array control panel in the primary rack, move the PS ENABLE switch
to the ENABLE position.
2. Move the PS ON/OFF switch to the ON position.
The following LED power sequence occurs:
BS-ON turns amber.
PS-ON turns green.
MESSAGE LED may turn amber if the disk array is not configured to "phone home,"
signifying a SIM was generated because the disk array lost power unexpectedly.
READY LED turns green, signifying the system is ready.
CAUTION:
Power on can take several minutes and is not complete until the READY
LED turns green.
3.
Move the PS ENABLE switch to "DISABLE" (opposite the ENABLE position).
