Is it possible to have raw access to LUNs from guest LDOM ?
Scenario is - 2 mpxio HBAs conected to control domain, 20 LUNs presented, 10 for ZFS filesystems inside LDOMs and 10 with raw access for HORCM operations inside LDOMs for switching TrueCopy pairs. So each LDOm should have exclusive access to two LUNs. This is requred for campus cluster with TrueCopy replicated storage for HA service running inside two ldoms.
We do not have T4 connected to storage yet and I can't check output of ldm list-io, but I've yet to see any examples of such setup on the net so a bit worrying if this possible at all.

You might be looking at PCIe Direct I/O - This extends current PCIe support to enable you to assign either individual PCIe cards or entire PCIe buses to a guest domain.
You would probably need more pci cards on different slots
