Figure 4.20 Problem with the ports that will block using in a virtual SAN
Here are some key steps to take when trying to resolve supportability with NPIV:
1 . Make sure that the HBA supports NPIV. This seems obvious, but check the
specifications of the HBA to ensure that it will work with NPIV.
2 . Check whether NPIV is enabled. Many HBAs ship with NPIV disabled by default.
Use whatever management application is available to ensure that NPIV is enabled.
As shown in Figure 4.21, I used the OneCommand Manager tool to see if NPIV is
enabled on my Emulex card.
3 . Update the firmware for the HBA and the driver on the Hyper-V host. Note that if
you update the firmware, it may reset NPIV to be disabled again, so you will need
to reenable it. In my experience, a firmware and driver update is often required to
fully enable NPIV.
