The NVRAM board failed to respond to an Identify Controller command.

During periods of I/O inactivity, an Identify Controller command is issued to make sure that the NVRAM card is still healthy. If the NVRAM card does not respond, the card might have failed and the system will force the node to reboot.

Administrator action

Reboot the node. If the event clears and does not recur, no other action is required.

If the event persists, gather logs, and then contact EMC Isilon Technical Support for additional troubleshooting. For instructions, see Gathering cluster logs.
