I currently have four active Brocade switches, two in fabric A and two in Fabric B. I'm adding a new switch to each fabric, then removing an old switch from each fabric.
The old switches are empty (no connections except for the E port connection to the other switch) but are also the Principals for their respective fabrics.
Any horror stories I should know about regarding "fabricPrincipal -f 1"? I backed up my configshows, and it all sounds so simple... but thats usually when the wheels come off.
After a little extra research, also I'm wondering if - in my "two Brocade switches per fabric" world - I even need to bother with forcing the principal setting on a switch...
