Yes it is possible. Have a look at the documentation: Designing High Availability Solutions with HP Serviceguard and HP Integrity Virtual Machines

Hi Sen_ux

Can the VMs reside on the same physical system?

Thanks!

Yes it can be on the same physical system, but it means you will not survive when your hardware goes down, so it is not a good option. It will only help you Ä±n case of software/OS problems.

This is more for a learning purpose. As I have never tried this activity before. Moreover, there is a lack of h/w resources. That's why I am trying to figure out what might be possible in a spare vpar of SD32B.

I just want to try out a basic cluster configuration

Pls suggest.

You can not install HP integrity VM on vpar. You need an npar for this.

installing VM is not possible on VPar . so its not possible in this case . if you are only trying install the cluster than you can try single node cluster . This is only if you have never installed any cluster

Hi Turgay

Thanks! So, I get it ... I can't utilize the vpar, an npar is out of question

Hi Jupinder

Thanks! I never really had a chance to install the simplest cluster. Pls guide me on trying with a single-cluster node. Resource available with me is
just 1 vpar of the SD32.

I am really getting appreciable input from u guys. Thanks!

Just search on itrc "single node cluster" there are lot of messages about it. One of them:

which verison of HPVM you are using?
well download the admin guide from docs.hp.com and there is a capter on how to use service guard with integrity VM.
there are a couple of ways to configure

1) SG comprises of 2 or more VM in same physical box.
2)configuring VMs as package and SG at host level.
for this hpvmsg_package is the script for HPVM 4.1
