▼ Change Port Topology from Fabric to Loop
XgOS supports changing a SAN topology or migrating from one topology to
another—for example, changing the port topology from Fabric (f) to Loop (l). You
can set the port topology type by using set fc-port topology command.
Changing the port topology can be done in real-time and does not require an FC
card reset.
To change the topology type from f to l, or l to f without resetting the card, follow
this procedure:
1. Display all vHBAs and note which ones are on the port where the topology will
be changed.
For example, assume port 9/2 will have its topology changed:
show fc-port 9/2 vhbas
