brocade_switchshow_aliases

Pulls switchshow from a fabric of brocade Fiber Channel switches, and shows aliases with WWNs

Short version: switchshow is great, if you can memorize WorldWide Numbers.

I can't.

So I wrote something to pull the zoneshow information, parse out the aliases data, and where a wwn appears in switchshow, it will also display the alias for the WWN if there is one.

Bonus: This understands how to get WWPN's from L-Port, and from NPIV F-Port ports.

Assumptions:

1. A single host can access SSH for all of your switches in a fabric.
2. All switches in a fabric have the same username/password pair with the rights to run 'switchshow', 'zoneshow', and 'portshow'. You'll be prompted for that username/password at runtime.

Outputs: This will create a zoneshow.{fabricname} file, which has the zoneshow data.

This will create a aliases.{fabricname} file, which has a cleaned up alias data for the fabric (pulled from zoneshow).

This will create a switchshow.{switchname} file for each switch in a fabric which has the cleaned up switchshow output, augmented with the alias data, and with NPIV and L-Port data exposed.

Steps to get it working:

1. Modify the config file: get_brocade.conf

This config files defines which switches are in which fabrics. The file has lines in the form {switch_host_name} => {fabric_name}. Specify as many switches and fabrics as you want. Each run of the command can analyze one fabric's switches.

2. run 'get_brocade.py {fabric_name}'

3. read output.
