System Controller Hangs During Power State Change

During operation on a farm with a large number of servers, the system controller sometimes hangs indefinitely. If this happens, perform the following steps:

1. Stop the Farm Manager process for the affected farm. To determine the process identification (PID) of the corresponding Farm Manager process, type /usr/ucb/ps -auxwww | grep "com.terraspring.cs.fm". In the list that displays, look for the process with the farm ID in the command-line arguments.

2. Use the kill command (or kill -9 if necessary) to stop the identified process and any child processes.

3. Power cycle the hung chassis. The system controller should be accessible after the power cycle. If not, contact your technical support representative.

4. All server blades on the power-cycled chassis will lose power and replaceFailedDevice requests might be filed before the blades are done rebooting.

5. Restart the aborted farm operation.

6. Delete any replaceFailedDevice requests on the rebooted chassis by executing request -d request-ID.
