Recovering From A Power Outage To The Disk Array; Manual Restart Of The Disk Array After Power Is Restored - HP StorageWorks XP1024 - Disk Array Owner's Manual

Recovering from a power outage to the disk array

Manual restart of the disk array after power is restored

Caution
XP128 hardware
If AC input power is lost, the disk array maintains its state and recovers
when power is restored. The array cache is backed up by batteries that will
maintain its state for a minimum of 48 hours. This length of time will
provide coverage for most outages. In cases where the outage will extend
beyond 48 hours, the batteries can be replaced by a HP to extend the time,
if necessary. To extend the backup time beyond 48 hours, you must notify
HP support in time to receive service.
Before you restore power to the disk array after an outage, HP recommends
you have an electrician check the power to ensure it is stable and clean.
You may opt to call a trained HP representative or you may restore power
to the disk array yourself:
1. Move the ENABLE/DISABLE switch to the ENABLE position. Move
the PWR ON/OFF switch to the PWR ON position
items 11 & 12)
2. The following LED sequence will occur:
The BS-ON LED
the PS ON LED (10,
The CHANNEL LED
for every adapter installed.
The MESSAGE LED
your disk array is not configured for automatic maintenance
notification, signifying a SIM was generated (because the disk array
went down unexpectedly).
Finally, the Ready LED
when the system is ready, which may take up to 10 minutes, depending
on the number of disks installed in your disk array.
3. Move the ENABLE/DISABLE switch to the DISABLE position.
