After an AC power interruption, some indicator lights on the front panel may remain off for a while. The Xserve RAID otherwise works normally, and the lights eventually come back on.

Products Affected

Xserve

Symptom

Though the Xserve RAID is otherwise working normally, you see these symptoms:
  • The fibre link channel lights are not on.
  • The host channel activity lights are not on.
  • The RAID Admin application reports "Controller not ready".


Solution

If the Xserve RAID has the optional Cache Battery Backup Modules, this may occur after an unplanned AC power interruption. You should not see these symptoms if you use the RAID Admin application to shut down prior to turning AC power on and off.

These symptoms do not indicate that anything is wrong with your system. If the RAID otherwise appears to be working normally, you should continue to use it. The lights should return to their normal behavior after a period of use.
