Hi Folks,
I'm an engineer working on the NPIV project,
http://opensolaris.org/os/project/npiv/, which is a method for virtualizing a
FibreChannel Port.
It is considered useful in virtual environment as Xen and Logical Domain as
each virtual system could have its own FC N_PORT_ID and storages via the
virtual port and the virtual port could be still available after migration
therefore associating storage.
However I'm thinking if NPIV could also be applied to Zones, and implementing a
prototype.
The idea is to add a resource type as 'npiv' and three resource prop for it,
'vpwwn'(virtual port WWN), 'vnwwn' (virtual node wwn) and 'ppwwn'(physical port
wwn). A subcommand in global scope, 'npiv-attach' is also added to attach
devices from the virtual FC port.
Here is a sript showing how it should work,
