Hi there,

I have exactly this environment (multiple VLANs) and HACMP. There is no need for VLAN tagging.

The thing you need to get your head wrapped around, is to think of the VLAN as just a physical wired segment of your LAN. The VLAN has an IP network defined on it (10.0.41.0/24, your service IP VLAN), but that doesn't mean it won't switch other IP network traffic as well (say IP network 192.168.1.0/24) (again, just think of the VLAN as a physical ethernet wire). You just can't route your 192.168.1.0/24 network off the VLAN (which isn't needed anyway in HACMP for boot IPs).

So, given the above statements, you provision your AIX adapters into your service VLAN. Your boot addresses go on a non-used IP network (just has to be the same subnet mask as your service network) ie 192.168.1.0/24, your persistant and service IPs then get allocated from the VLAN network, ie 10.0.41.0/24.
