Checklist
Ensure that the virtual devices are zoned correctly.
Activate the zone set.
For a host/virtual device connected to a Cisco MDS 9124 Fabric Switch, ensure that there
is a rewrite-capable SDV-enabled director switch in the path.

Debugging and Verifying SDV Configuration Using the CLI

Several commands involving multiple configuration tasks can be used to debug and verify the SDV
configuration.

CLI Commands for Debugging and Verification of SDV
All SDV devices, and the real devices accessing the SDV devices, must to be attached to SDV
enabled switches.
SDV does not work for devices connected to non-MDS switches.
Broadcast zoning is not supported for a zone with a virtual device.
IVR and SDV cannot be used for the same device. In other words, a SDV-virtualized device cannot
be part of a IVR zone or zoneset.
Virtual device names should be unique across VSANs because they are registered with the device
alias server, which is unaware of VSANs. For example, if you have enabled SDV and have registered
a name, vt1 in both VSAN 1 and VSAN 2, then the device alias server cannot store both entries
because they have the same name.
