2. Project Summary
2.1. Project Description:
Support NPIV device in Solaris xVM
2.2. Risks and Assumptions:
This work is for Solaris xVM hosts only, therefore guest domains
configured with
NPIV device may not be able to be migrated to hosts running on other
platforms,
e.g., Linux.

4. Technical Description:
4.1. Details:
This project introduces two extensions for Solaris xVM utilities to
configure NPIV
devices with paravirtualized guest domains. NPIV is enable in Solaris
by PSARC
2007/501, refer to section 5 for more info.
The first one is to attach a specified LUN from a virtual FC port to
guest domain.
xVM hypevisor in Solaris is extended to accept a new type of blk
device, npiv,
and to trigger according script to create the virtual port on specified
physical port, discovery the lun on specified target and finally attach
it as
a normal blk device to guest domain.
The second one is to attach a specified virtual FC port to guest domain
as
a pseudo device. 'Pseudo' means there will be no corresponding frontend
in guest domain
for that virtual FC port. xVM hypevisor in Solaris is extended to
accept a new kind of
device, pseudo, and to trigger script to work on different pseudo
devices. Currently
the only pseudo device will be NPIV port and the corresponding script
will create
the virtual port on specified physical port and then,
1)attach existing luns from that virtual port to guest domain
2)register a script for device sysevents happenning on the virtual
port, afterwards newly
added/deleted luns will be attached/detached from the guest domain.
Eigher way the npiv device is able to be migrated if the remote the
destination host has the specified physical FC port and on the same
Fabric with the
physical port on source host.
