Checking cluster configuration

About the Cluster Configuration Checker

Network Appliance provides a Cluster Configuration Checker utility that you can download and run to ensure against the most common configuration causes of failover problems between clustered filers.

Where you can run this utility

You can run the utility, cf-config-check.cgi, as a command from a UNIX shell, or you can install the CGI script on a UNIX Web server and invoke it from a Web browser.

rsh requirements

In order to run the Cluster Configuration Checker utility, you require rsh access to both clustered filers.

What the Cluster Configuration Checker finds

When run, the utility detects the following error and warning conditions in the clustered filers:

Service license errors. If the services licensed on the two clustered filers are not identical, some services might become unavailable on failover.
Options settings errors. If the options settings on the two clustered filers are not identical, some options will change on failover.
Network interface errors. If the network interface settings are incorrect, client connections might be lost on failover.
Data ONTAP version differences between the clustered filers.
Clustering licensed but not enabled on one of the clustered filers.
FCP is licensed on the cluster but the fcp set cfmode settings on the cluster partners are inconsistent.
