The node cannot perform read or write operations on the authentication database files.

This event typically appears when a node does not have quorum or otherwise cannot access the authentication database files.

This event also sometimes appears when a node starts up. In that case, the event frequently resolves itself within five minutes. If the event resolves itself, no action is required.

Administrator action

If the event does not resolve itself within five minutes, review the node status through the Isilon web administration interface and resolve any apparent issues.

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