what RESOURCE_NAME to poll in MCSG packages

[Thevenet_1]

Hi
I have 2 rp5470 with Oracle RAC database
They are connected trough a San to an EMC disk array ...
Everything is redundant, network...

I don't really see what kind of EMS resources do I have to add as "RESOURCE_NAME" in my package configuration files ?

Some examples of "real world" would be helpfull.

I know that I can put disks or network interfaces but what for ? they are all redundants

Serviceguard will initially only respond to node failures, LAN NIC failures, package failures and package service failures.
If there is some other system resource that is critical to operating the package, then you have the ability to specify that resource in the package configuration file.
One of the more common resources configured into the package is /vg/vgName/pv_summary
This permits the system running the package to detect if all links to a disk have failed and react to it.
Unfortunately the only reaction which would force the package to failover would be to reboot the node where the link was broken.
A system will not gracefully shutdown where a umount cannot be released because I/O is being blocked.
