Oracle VM for SPARC - control/io domain dilemna

Hi all,

My internal SAS disks (4 of them) are all sitting on the same controller/pcie device which is now being own by my default primary aka io aka control domain.

I have created a vdisk server, that serves slices on these 4 disks to guest domain and everything is working fine.

The issue is that, whenever I need to patch my control domain (reboot) the guest domain will be affected due to the fact that the entire IO/PCIE device is own by primary.

/SYS/MBU/SASHBA PCIE PCIE0 primary OCC

==================

q1) Does this means that I have no way to create another separate IO domain so that whenever I patch my control domain, my guests wont be affected ?

q2) If I have another 2 PCIE device (hba cards connected to SAN), can I assign them to another IO domain, then from that new IO domain, create a vds service and serve disks to guest domains instead ? (come to think of it .. this IO domain need its OS to run, unless I am doing SANBOOT, else this IO domain will still run from vdisk allocated from control)

q3) if a guest domain has no dependencies on the control domain, will patching the primary/control domain cause guests domain to go down ?

Regards,
Noob
