Jack,
I think that is very interesting and "native" extension of zones.
Couple of questions.
1. What happen if more targets are being made available
for the virtual initiator ? Does one need to get into zonecfg
and run npiv-attach again ? If not, why to run it in first place ?
2. Will cfgadm, luxadm, fcinfo etc commands work from
the zone as well ? If not, what is the interface to administer/
configure the virtual HBA from the non-global zone ?
Very much excited with your work !
