Recovering from an unplanned power outage

Manual restart of the disk array after power is restored

Caution
XP12000 Operations
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 48 hours, depending on the selected battery operation
mode. For more information, see "Backup batteries"
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 DKC control panel [Figure 2
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.
• SUB-SYSTEM MESSAGE 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.
• SUB-SYSTEM READY turns green, signifying the system is
ready.
