I am not the db2 admin in this project, I just work on the linux side of things. Can you recommend how to setup db2 in this case? Here´s the layout:
Two identical machines meant to be a failover pair. They each have their own OS disks and installations, then there is a second disk via fiber that swaps back and forth between them as a fault is detected by heartbeat. The problem we ran into before is that when db2 was installed on machine1 into the failover disk, when it was shifted over to machine2 it failed to startup because (as I understand it from how it was described) the database figured it was on a separate host because the hostname was different. I realize this is not a db2 support forum, but it is related to my issues with the linux HA software. How does one setup the db2 instance to not balk at starting with a different nodename than it was installed on - or how do you make it not care to begin with?
