We had an unplanned (ha!) HACMP event yesterday. For whatever reason,
the secondary node couldn't activate the resource group (read: I
believe the admin who configured HACMP didn't set it up right). At
any rate, I restarted the primary node, restarted Cluster services and
expected it to swap the service IP onto the boot adapter.
Unfortunately, it didn't. As this is a mission critical (man, I hate
that term) app, I ifconfig'd the interface back to the service IP so
the users could get back in. Of course, errpt is showing 'local
adapter misconfiguration.'
This morning, I took the secondary node out of the cluster, manually
shutdown all of the applications on the primary node, then rebooted
the primary node, thinking that HACMP would do the boot->svc IP swap
on reboot. Not so. I tried synchronizing cluster resources,
activating resource group, etc. (with and without the secondary node
in the cluster) all to no avail. I wound up ifconfig'ing the
interface again so the users could do their work.
Any thoughts on why HACMP would not automagically swap the boot and
svc IPs? I'm definitely not HACMP certified, but from what I've read
it should acquire the resource and setup the topology. Am I missing
something?
