This sounds like the case until you zone update on attach written and integrated. 1. http://mail.opensolaris.org/pipermail/install-discuss/2007-June/004625.html > I can't seem to find anything in the VCS 5.0 documentation that > includes the attach/detach commands only some discussions that say > this may be included some time in the near future.

This is a new product for those times where a 32-node peer-to-peer cluster does not quite do the job. It uses agents that look just like VCS agents and are apparently a fork from the VCS 5 agents. I would expect that at some point these will sync back up. FWIW, creating the zone on the other machine can be relatively easy: node2# scp node1:/etc/zones/fazone.xml /etc/zones/tmp.xml node1# zoncfg -z fazone create -t tmp verify commit exit node1# hagrp -offline fazone node1# zoneadm -z fazone detach node1# cd /zones node1# tar cvf /tmp/fazone.tar fazone node1# zoneadm -z fazone attach node1# hagrp -online fazone node2# scp node2:/tmp/fazone.tar /tmp node2# cd /zones node2# tar xvf /tmp/fazone.tar node2# rm /tmp/fazone.tar node1# rm /tmp/fazone.tar node2# zoneadm -z fazone attach The one thing to verify is that VCS creates some sort of an account (in their security system, not the OS) and stores the credentials in the zone. This is needed if you want to run ha* commands from within the zone. You may need to fix these up - or not. So far I haven't had a lot of need for running ha* commands in zones, but I'm sure some day I will come across an agent that needs it.
