Adding a New FC Switch, E-Port Segmentation

I have a Brocade 5000 fibre channel switche and am adding a new Brocade 6510 but am unable to get the new switch to join the existing  fabric.  I'm getting the following errors on the connected ports:

 

E-Port segmented,(Non-zero reserved field)

E-Port segmented,10:00:00:05:1e:90:6d:dc (incompatible)

 

Following are details for both switches:

Hello,

 

In Fabric OS v7.x, an ESC frame is used to exchange fabric parameters to detect Enhance TI Zones, interoperability mode, and Virtual Fabric FID conflicts. If at any point during the ESC frame exchange, a link with incompatible parameters is detected, the switch running Fabric OS v7.x does not join into the existing fabric.

Fabric OS 7.x on 6510 is only compatible with Fabric OS 6.2.2+ on the 5000 and this is the RCA of the segmentation.

 

Check below (sample):

 

fabstatsshow        :

 

CURRENT CONTEXT -- 0 , 128

Domain ID forcibly changed:       0

Segmentations due to:
                  Loopback:       0
           Incompatibility:       7 <   135  Tue May 22 13:32:49 2012

 

Fabric OS:  v7.0.1
13:28:20.395856 Segment: Incompatible, Unknown              D2,P1  D2,P1  135   NA

Re: Adding a New FC Switch, E-Port Segmentation

Ugh, thank you!  So a few more questions:

 

1.  FOS 6.1.0c (running on my 5000) is not compatible with FOS 7.3.2 (running on my 6510) and there aren't any workarounds?

 

2.  What version would be recommended for my 6510 if I want it backward compatible with 6.1.0c?

 

3.  Is the upgrade from 6.1.0c to 6.2.2 (which is compatible with 7.3.2) a non-disruptive upgrade on the 5000?

Re: Adding a New FC Switch, E-Port Segmentation

1. No workarounds.
2. 5000 is end of life, while life goes on. 6510 is upgradeable to FOS 8.x which is incompatible with 5000 at any FOS level. You basically need to migrate your fabric and switch your 5000 off if you want to run a supported environment.
3. Yes, and I advise to upgrade it not to 6.2.2, but to 6.2.2g. If you want to leave it running for some more time, I advise updating it further to 6.3.x and 6.4.x. according to the Target Path.

Re: Adding a New FC Switch, E-Port Segmentation

Thanks for the help!  One more question; is 6.2.2g "safe"?

 

This is actually HP-branded switch (HP StorageWorks 4/32B SAN Switch) equivalent to the Brocade 5000 but I found the following note:

 

Do not provide FOS 6.2.2g or 6.4.3a to a customer or install it at a customer's site without permission from Switch Engineering.

 

 

Assuming it is, it looks like I can do a disruptive upgrade directly to 6.2.x from my current version.

Re: Adding a New FC Switch, E-Port Segmentation

Oh! You're right, Target Path document dated Feb/2015, which is the last one to include FOS 6.2 - it also mentions 6.2.2f, so you'd better stick to this version. Good luck!

Re: Adding a New FC Switch, E-Port Segmentation

Thanks! I managed to do a non-disruptive update to 6.2.2f and, after the HA restart, the new switches downloaded the fabric and things look good. Appreciate all the guidance!
