You do not need to create two separate copies of zones. You can
accomplish zone failover between nodes on SAN-attached disk with the
Zone VCS agent on VCS 4.1 and 5.0. You can import non-global zones onto
all VCS nodes that have an /etc/zones/index entry as well as the same
/etc/zones/<zonename>.xml as eachother. Symantec told me they will be
adding a proper detach/attach into 5.x. When they first made the VCS
Zone agent, there was no such functionality in Solaris, but it has been
now since Solaris 10 update 3. You can contact me off-list if you would
like more specifics.

Subject: Re: [zones-discuss] VCS failover of non-global zones

So basically today it sounds like we'll still need to build 2 seperate
zones on each physical server for failover purposes.  Especially in
patching situations where I see this is the only workaround, unless
someone has devised a way to only have one zone built and failed over
via a SAN volume on each physical node and patching would not be an

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.  I'm assuming this is the same
with SUN cluster 3.
