Hello,
I am trying to implement HA with IPAT / Aliasing. My network group
has given me a number of class C networks (numbered consecutively,
10.5.36.x through 10.5.44.x) for boot / service addresses / resource
groups, but we are having problems bridging the gap between 'unix talk'
and 'network talk'. 10.5.36.x will be used for boot addresses, and
37-44 for service addresses.
I have done HA quite a number of times with hardware IPAT, but am
relatively new to IPAT aliasing. The design goal is to allow
'stacking' of multiple subnets (as many as 8) onto a single NIC. Each
of my assigned networks are on a separate VLAN right now, on Cisco
equipment. How / what do I request from my network group to allow my
host to see all 8 networks on a given port? (same for my second nic).
Is there something they can do to 'stack' the port with multiple VLANs,
do I configure vlans on the card, etc, etc? Right now, I am only able
to get one vlan assigned at a time.
Hardware is pSeries 630/690/550/etc, AIX 5.2 ML4 and/or 5.3, and HA
5.2. Cisco is 6500 series, not sure rev. Does anyone have some
specific configs / settings they can share?

Thanks in advance,
Greg
