I have a customer who would like to remove a dark fiber link between sites.They currently have 4 FC switches and have 2 FC links with 2 x Fabrics A + B so effectiveely loosing cross site redundancy on Fabric B what is the best way to reconfigure the 2 FC switches that where in Zone B on either site to allow for local SAN redundancy ?
Any gotchas to be aware of ?

Can you provide a drawing of actual configuration? And show which link Customer would like to remove?

Attached is the drawing you provided.
What kind of switch are you using?
Does any ports are available in Fabric B switches?

If you would like to continue to use all previous switches, different options exits. More or less disruptive to implement.
Depends if free ports on existing configuration, if switches are VF capable.
Will be good to increase bandwidth of ISL link connected to dark fiber if possible.
Better to do as much as possible local switching.
See pdf attached.

If you decide to remove 2 swicthes, there is not much to do.
For optimization, make sure the replication ports are using repartited Virtual Channels (VC). Destination PID select the VC used.

Those types of switches do not support Virtual Fabrics.
