Hi Paul,
Currently, to make a LDoms guest domain HA, you would
run SC inside that guest domain, essentially treating it
as a SC "node". If that "node" fails, all services within it
would be failed over to other "node"s in the cluster and
achieve HA that way.
What you are suggesting is closer to the "Failover Guest
domain" model (similar to "Failover Zones" model you seem to be
alluding to). That is currently not possible, but we are
looking very actively into it.
Check out my blog entry:
http://blogs.sun.com/SC/entry/ldoms_guest_domains_supported_as
and comments on that entry. It seems several people are interested
in it. Given that you are internal to SUN, can you contact me
offline with your specific customer needs? That would help us
prepare a business case and help move this along?
Thanks,
-ashu
