Sorry for the late reply, but I was in Turkey doing my design exam last week without much access to internet.

I am not sure why do u need a permanent VPORT, as you just said the VPORT get destroyed each time you shutdown the VM.

Though what normally you care about is to sustain your WWN number for the VM across reboots & power recycles just like a physical server & this is possible. Actually by default in vSphere a VM will sustain its WWN number generated when NPIV is enabled. In particular in the Fiber Channel NPIV tab you will have two options on maintaining the WWN number for the VM across reboots as follow:

- Leave unchanged (The default & will maintain WWN numbers across power cycles)
- Generate New WWNs (Will generate new ones).

I hope this help,

Thanks for sharing this info with us, much appreciated.

Just out of curiosity, Is it possible to setup a permanent VPORT WWN pair?

My understanding is that the VPORT has its own unique identifie and that the VPORT is destroyed on the host when the VM is powered off.

Thanks a lot
