detect failover in suncluster

[Tim Dunphy]

Hello,

 I've been asked to check whether members of a number of sun clusters we have here have 'failed over' from primary to secondary. The clustered machines are all Oracle Databases. The idea is that if one node goes down then the secondary in the node becomes the primary Database. Apparently this is all achieved through Sun Cluster, which I have to admit I'm not well versed on.
 
 I did find a plugin in the nagios exchange that checks the components of Sun Cluster - things such as IPMP, resource groups and quorum. But what I don't think it offers is to tell if one node fails over to another. It could just be that I don't know enough about Sun Cluster to correlate the options in the check. 

Here's the usage for the check:

[db07-dc2:~] root% /opt/nagios/libexec/check_suncluster -h

Usage: check_suncluster [-t, -q, -g, -G resource-group, -r, -R resource, -i]
Usage: check_suncluster --help

Sun Cluster check plugin for Nagios

-t: check transport paths
-q: check quorum
-g: check resource groups
-G: check one individual resource group
-r: check all resources
-R: check one individual resources
-i: check IPMP groups

Does anyone out there have any suggestions on how I may get this check or perhaps another one you may know of to indicate whether a Sun Cluster (Database) node fails over and a secondary becomes primary?


Thanks in advance,
Tim
