PRIMECLUSTER Wizard for NAS Configuration and Administration Guide 4.2 - Solairs(TM) Operating System -

3.1 Corrective action during failover

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

UserApplication log

When errors are detected in userApplication in a cluster system, check the application log and take corrective action.

PRIMECLUSTER Wizard for NAS log

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

The format of the log file is as follows:

RemoteFileSystems log

When an error is detected in networks or in NAS, the RemoteFileSystems resource enters FAULT. Check the RemoteFileSystems log (/var/opt/reliant/log/hvdet_nfs*) and take corrective action.

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.
