VM has been started after the timeout period (90 seconds). Please
review the LUN mappings for the virtual port. (Virtual machine ID

You may need to start this way initially so that the WWPNs show on the Fibre
Channel switch to allow them to be zoned. Then, after available storage is zoned, the
result is another event log being written to show that storage is now available on the
vFCA:

I want to step back now and cover why each vFCA has two WWPNs. One of the most
used features of Hyper-V is Live Migration, which is the capability to move a virtual
machine between hosts with no downtime to the virtual machine. It was important
that virtual Fibre Channel did not break the ability to live-migrate a virtual machine.
However, if a vFCA had a single WWPN when a virtual machine was moved to another
host as part of the migration, it would be necessary to disconnect the connection to
the storage temporarily so that the WWPN could be used on the target host, which
would result in storage access interruption. Therefore, each vFCA has two WWPNs,
which enables the second WWPN to be used on the target of the Live Migration,
enabling both the source and targets to be connected to the storage during a Live
Migration and avoiding any interruption. As Live Migrations are performed, the
WWPN used will switch between the A and B set with each migration. This is
important because when you are zoning the storage, you must zone both the A and B
WWPN, or if you live-migrate the virtual machine, it will lose access. It may be
necessary to perform a Live Migration of the virtual machines to activate the second
set of WWPNs to allow them to be zoned on the switches if you cannot manually
specify WWPNs that are not currently visible to the switch. This means that the
process may look like this:
1 . Start the virtual machine.
2 . Connect to the switch, and create an alias (or any other construct, depending on
the switch) for the visible WWPNs.
3 . Live-migrate the virtual machine to another host, which will trigger the other set
of WWPNs to activate.
