Consider this post in about middle about domains, c/p from my previous post

As for bare metal domains (primary,secondary), let me offer a short explanation of domains as i understand it...
For instance, you have sparc t4-2 with two sockets, two 4 port network cards and two 2 port FC card.

You can create two hardware domains - primary and secondary, in which the actual I/O hardware is splited between those two domains (each has one PCI card and one FC card and one CPU socket and memory ).

Now you have a situation that you have one t4-2 sparc which is actually two machines separated on hardware level. So all LDOMS created on primary domain will use its resources (CPU,PCI - half of them) and ldoms on secondary will use its resources (other half)

Basically, if one socket fails due to hardware failure, only the primary domain and guest ldoms on them will fail, while secondary and guest ldoms on it will continue to run.
Those setups complicate things considerably and are done on machines which have more resources in redundant matter (like 4 cards or 4 sockets, 2 phys cards per domain for redundancy etc.)

For your setup i guess you need (keep it simple - as per scheme in the begining) :

One primary domain (bare metal)
One vsw created on top of the aggr0 interface in primary domain.
One vnet interface added to LDOM from primary-vsw on primary domain.
One VDS (virtual disk service) in primary domain per guest ldom (sneezy-vds@primary, otherguestldom-vds@primary etc.) in which you add disks for ldoms.

This is the entire topic :
Guest LDOMS on same subnet cant ping eachother

Bare in mind that most of the network stuff discussed here is patched, and there are some more additional options (like DLMP).

Hope that clears things out
Regards
Peasant.
