Generate zoning commands from zoneshow output on brocade switches

There have been a number of times where I've need to take zoning from one fabric, and create it on another fabric. Typically this is when doing switch migrations where I am going to create one or more new fabrics, re-create the zoning, then move the host and storage FC cables one fabric at a time.

This happened recently when I was migrating to new switches, and the old switches didn't have a license to create an ISL. 

This is also a handy way to have a backup of your zoning configuration.

 

I have a linux VM running on my laptop with ksh installed, so I can just use it there.

All you need is to SSH into the switch you want to grab the zoning off and run the command "zoneshow". Put the full output into a text file onto the linux or AIX server you are going to run the script on, fill out the variables in the script with the config name you want to use, and if you want to create the config, and it will spit out the commands to create the zoning.

 

These are:

 - alicreate (create aliases)
- zonecreate (create the zones)
- cfgcreate (create the zoning config)

- cfgadd (add the zones to your zoning configuration)

- cfgsave (save the defined zoning configuration)

- cfgenable (enable the zoning configuration to the fabric) 

 

Hopefully this saves someone some time.
