MDS9509, zone active but not used

Question

I mostly use ECC 5.2 SP5 to manage (zone) the switches, but I have used FM 3.1 and Cisco Cli 3.1 . Using any/all these tools is there some way to detect that an active zone is not actually being used? I'm in the process of cleaning up zones and while I know most of things that can be removed there can be some unpleasant surprises

Ok, I see the challenge you are referring to. Not having control over you entire SAN infrastructure is going to make that more difficult and an ongoing task it sounds like.

Using the command "show zoneset active vsan XX" can still help you in this. If you run the command it will show all the zones in the active zoneset, but it will also place an asterisk next to wwn's that are currently logged into the fabric.

Below is the same zone copied from the output in the "show zoneset active vsan XX" command from one of my switches. The first one is with the server online. The second one is how the zone looks with the server shutdown.

zone name XXXXXX vsan XX
* fcid 0x020000 [pwwn 21:00:00:e0:8b:85:fc:d1]
* fcid 0x021eef [pwwn 50:06:01:63:30:60:36:22]
* fcid 0x021def [pwwn 50:06:01:6a:30:60:36:22]

zone name XXXXXX vsan XX
pwwn 21:00:00:e0:8b:85:fc:d1
* fcid 0x021eef [pwwn 50:06:01:63:30:60:36:22]
* fcid 0x021def [pwwn 50:06:01:6a:30:60:36:22]

You could also compare the "show zoneset active vsan XX" output with the "show flogi" or "show fcns database" output. This will give you the list of wwn's logged into the switch that you can compare against the list of zone memberships.

Bruce,You can look at the active Zoneset to determine which zones are in use. With the CLI you can compare the current active zoneset against the entire list of zones for each VSAN.show zoneset active vsan XXshow zoneset vsan XXIn the Fabric Manager GUI you can enter into the Zone Database for each VSAN and by viewing the Zoneset container you will see which zones are active.Is that what you were looking for?Aran

First we are using wwn zoning. Determining active zones is easy, the question is 'is an active zone actually being used'. Lets say a SAN attached server P1 gets replaced. By our convention, the hba should get put in a cleanup pile and a change control generated to clean up zones and masking. What has happened is someone reuses the card in P2 and since its already zoned to our production DMX all they do is mask the necessary disk. So I come along and say 'this zone for P1 is not used, after all the server is gone'. I remove the zone and server P2 quits working because the zone was still being used.
