PRIMECLUSTER Wizard for NAS (PRIMEQUEST) 4.2 Configuration and Administration Guide - Linux -

3.1 Corrective action during failover

The PRIMECLUSTER Wizard for NAS does not support to monitor NAS(Control facility of the NAS-Cluster is optional). When the RemoteFileSystems detects an error in network systems or in an NAS device, or the GLS resource detects an error in networks, failover occurs. If a Wizard product is used, the wizard might detect a failure, and failover occurs. Confirm the following and take corrective action.

UserApplication log

When an error is detected in a user application in a PRIMECLUSTER system, check the application log and take corrective action.

In the PRIMECLUSTER Wizard for NAS, operations and error messages are output to the following log file. For the error messages, see "Chapter6 Messages".

GLS log

If you use GLS to connect cluster nodes and NAS, and this leads to error in a network system, the GLS resource enters FAULT. Check the GLS log and take corrective action.
