Cluster Resource Failover

[sattanathan]

Hi,

I need to monitor the movement of few windows cluster resources(Around 20 drives ex. E drive, F drive etc..) between 3 servers(These 3 are Exchange servers). All the resources are from only one SAN and mounted on a virtual IP. From this Virtual IP these resources will be utilised by the 3 servers. At a instant of time 2 servers will be active and 1 server will be in passive. So these cluster resources will be always available in 2 servers at a instant of time. when the resource from any of the servers failover to another server i need to have an alert and a ticket should be generated. Please suggest me a way to monitor this.

I cannot monitor these resources locally in these 3 servers as it is generating 3 alerts for one failover which increases the number of tickets. So i am monitoring these resources at the virtual IP where these resources are actually mounted.

SNMP TRAP and Event Log monitoring are not possible as the server owner is not agreeing to enable SNMP TRAP and install further component on the server .

Please suggest me a way using any other plugin that can be used to monitor this resource failover.

Thanks,
Sattanathan.S

You could likely use WMI checks against the three servers although you may run into the same issue of getting three alerts. Otherwise from the virtual IP of the san, are you able to monitor these changes with snmp queries? It would not be as fast as a trap setup, however any differences would be relatively small in realtime.
