If you have many verdors SAN switch, and don't want to use compatibility mode between these, then use a transparent switch on Blade SAN switch, so it will show an Nport on external switch instead of using Eport.

<box 100% green |Qlogic change switch to Nport virtualization>

ssh to switch ip, login USERID/PASSW0RD
admin start
config edit
set config switch
Change Transparent mode to True
Press enter through rest of prompts
config save
config activate

The switch reboots into Pass-thru mode. To change back to full fabric mode, perform the above operations but set Transparent mode to False </box>
