The NVRAM card is not responding and the node has been set to read-only.

Connection between the NVRAM card and the node was lost. In some cases, restarting the node will reload the NVRAM driver and restore the connection.

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.
