Automatic Restart When Power Is Restored - HP StorageWorks XP10000 Owner's Manual

Automatic restart when power is restored

Caution

HP recommends the use of automatic power on restart only if the power to
the disk array is subject to power conditioning equipment, such as a UPS,
to ensure that the power restored to the disk array is stable. If your site
does not have a UPS, HP recommends configuring the disk array for
manual restart, meaning the Auto-Power-On jumper, which is set during
installation by an HP support representative, is in the DISABLE position.
After a power outage, follow the manual restart procedure
after power has been restored and verified to be stable.
Automatic restart is enabled by your HP representative during installation.
With automatic restart enabled, the disk array automatically restarts and
returns to service when power is restored after a power outage.
During the automatic restart, the following LED power sequence occurs:
a. BS-ON turns amber.
b. PS-ON turns green.
c. 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.
d. READY LED turns green, signifying the system is ready.
Powering on the disk array can take several minutes, depending on the
number of disks installed in the disk array. Power-on is complete only when
the READY LED turns green.
