Right now those disk device path starts with /pci instead of /scsi_vhci. Yet they are showing up in format output ok. What is the trick to fix this without rebuilding install ISO image ?

easy -- don't rebuild the install ISO image :-)

ugh, too much work.
Try this (I'm sure I blogged this a few times, or maybe in the Nexenta knowledge base?)
I'm sure the procedure is in the email archives...

1. go ahead and do the installation.
2. boot into newly installed OS
3. edit scsi_vhci.conf
4. shutdown
5. boot from install media, go to shell
6. import rpool
7. export rpool
8. reboot into newly installed OS

ZFS is tolerant of path changes, but you have to trick the boot process.

The root cause is a deficiency in detecting multiple ports. The workaround is to override
in scsi_vhci.conf. The fix is known, just need to find the time...
