Drives will be powered off in five minutes to protect them from overheating.
Close the drive drawer before the service window timer expires. If you are not performing service on the node, make sure that the drive drawer is properly closed by sliding the drawer out and re-closing the drawer firmly and carefully. If the drive drawer is not closed before the service window timer expires, the node reboots, but the node will not rejoin the cluster until temperatures are within acceptable thresholds.
If the event does not clear itself when maintenance is complete, or if maintenance is not being performed on the node and the above steps do not resolve the issue, follow the instructions to gather logs, and contact EMC Isilon Technical Support.
