Xserve RAID: Only Fibre Channel Link Light Is On After Resetting Controller

If you hold the reset button too long during the reset procedure, the controller may stop responding.
Symptom

Only the Fibre Channel link light is on (both on the front and on the back of the Xserve RAID). In RAID Admin, the controller is amber, the corresponding blower is off, and the corresponding Ethernet link is down.

This occurs when the controller has just been reset and the reset button was pressed too long.


Solution
  1. Use RAID Admin to turn off the Xserve RAID.
  2. If cache backup batteries are installed, pull them slightly out of the RAID.
  3. Disconnect the power cables from both power supplies.
  4. After 10 to 20 seconds, reconnect the power cables and start the Xserve RAID.
  5. All LEDs on both controllers should turn back on. Wait for RAID Admin to update status until you see all modules are working again. This process can be expedited by quitting and reopening the RAID Admin application.
  6. Reinstall the cache backup batteries.
