failover on 4.5 hacmp

Hi All,

How do I trigger the failover on the second hacmp server?

Please give me idea and I will do the rest.

Thanks,
itik

Failover can be triggered by anything as unplugging a network interface cable to one of the nodes. Smilie

Do anything which interrupts the service of the primary server. Put to the extreme: rip out the power chord of the primary server.

Still there are less physical approaches to that. Here are some (non-destructive) possibilities ordered by velocity of the shutdown process:

"shutdown -F now"
"halt" / "halt -q"
"cat /etc/hosts > /dev/kmem"

Of course you can use the SMITty menu to initiate a "graceful takeover". This would leave the primary server even running.

I hope this helps.
