This event typically appears when maintenance is being performed on the inside of the node, while the node is powered on. Or, this event might appear if one of the NVRAM battery trays were pulled out.
- Make sure that the battery tray is properly inserted.
- If the node chassis is open, close the chassis.
If the event persists, gather logs, and then contact EMC Isilon Technical Support for additional troubleshooting. For instructions, see Gathering cluster logs.
