Using ServiceGuard Floating IP on VM Package

[DARREN NEWBOULD]

I have two C-Class blades configured as VM Hosts (IVM 3.50) and running four VM’s each.

One VM on each blade is a MySQL database running on HP-UX 11.23. The idea is that these databases run in a ServiceGuard cluster and as such, I have installed ServiceGuard on the hosts and configured the VM’s as packages.

After some teething problems, this cluster now seems to be working fine as regards failover. If I kill one of the database VM’s, SG starts the database VM on the other node (host blade) and this comes up fine.

However, the big issue I have just realised is that because SG is installed on the hosts, the floating address is assigned to the host and not the VM. This means that we cannot target the database using the cluster address. The idea for doing it this way is so that we could have two separate VM’s which could be patched while not running the live DB.

Is there any way around this or would we have to install SG on the VM Guest instead?
