VIO SAN Boot and NPIV
« on: March 18, 2014, 11:45:52 PM »
Guys

I did recently a fresh installation of VIO lpars using single path from SAN. VIO lpars are booting well from SAN now.

My question is that can i use same FC port which is being used currently for VIO lpars to boot , for booting AIX  client lpars using NPIV? In other words can i create Virtual Server FC adapter on VIO level on same port which is already being used for VIO SAN boot process ?

Please clarify ,

Thanks in advance for help!!!

Michael

The short answer is yes.

If the VIO server can see the LUNs as hdisk, then you will use VSCSI (mkvdev -vtd hdiskX -vadapter vhostX) and you do not need to do anything extra as far as the SAN is concerned.

If you are going to use NPIV you will need to create the vHBA (aka NPIV) adapter(s) in the client. If you are not planning on doing any LPM (Live partition mobility) it is enough to zone only the lower of the two WWPN that are created per virtual adapter.

Once these are zoned you use vfcmap -vadapter vfchostX -fcs fcs0 # this assumes your single active port is fcs0

Hope this helps.
