When the ILOM start /SYS command is issued to power on the host, it will occasionally fail with the following message:
start: Insufficient power available for this operation: The chassis Available Power must exceed the chassis Ticketed Power by greater than the power budget requirement of this blade (see power ticket denied message in the CMM event log)
The above message may not accurately describe the correct reason for the failure of the host system to power on. Although insufficient available power is one possible cause, other factors such as hardware malfunction, system faults on the peer node of the same blade, and/or chassis CMM failures may result in the same error.
If you encounter this error, do the following to help in identifying the source of the problem:
Check the health of the peer node on the same blade.
Check the health of the chassis CMM.
Inspect the system event logs for issues that might be related.
Confirm that sufficient power is available at the chassis level.
