The zone then comes online but does not failover. does not work for me. without cluster hooks, the zones start on either node without issue – my issue is that when I put in the zone resource by using the /opt/SUNWsczone/sczbt/util/sczbt_register script the zone stays on OFFLINE state on both nodes, clresource enable brings it online – after a while.

Thanks for the excellent blog entry. However one thing still does not work - the global zone controls the logical interface so I was not able to plumb the zones by it, how do I do that? It works!

" so how do I set the zonepath for the zone, I have one shared zpool that is where the zonepath will be, how do I create two zones on one zonepath? Please help Okay, I made it this far…..

Is it on shared storage? Is hazonepool local to cluster node 1? You mention: "Once the zones are installed, you should failover the shared storage to each node in the cluster, and boot the zones to be extra certain" How do I failover the shared storage to each node - where have you configured shared storage? In the command: clresource create -t SUNW.HAStoragePlus -g hazone-rg -p Zpools=hazonepool -p AffinityOn=True hazone-zpool

is Zpools a predefined/standard property?

You mention: “Once the zones are installed, you should failover the shared storage to each node in the cluster, and boot the zones to be extra certain”
How do I failover the shared storage to each node – where have you configured shared storage?

So for example you have node1, node2 each node is running zone's... now each zone I would want to mount the same SAN lun... (granted only one zone will be running application at a time so should hopefully avoid clobbering writes) Thanks Besides setting up a failover filesystem how would you setup a global file system to be mounted on all nodes in the cluster?
