SAN core migration

Good Day,

I'm in the middle of a SAN core migration from a Mcdata 6140 (eos 9.9)to a Cisco MDS9000(5.0.4c)

The Mcdata is the current principal and we have various Brocade bladecenter 4gb 20 port switches (6.2.2d) connected in AG mode.

The blade servers are all using Qlogic 4gb HBAs at the latest firmware level.

When everything is physically connected to the Mcdata all the blades work fine.

We vacated a BC and reconnected it to the Cisco director in AG mode and the first two blades installed can boot from san and work fine.

Each subsequent blade can not see the target luns. We have reproduced this over and over.

When we remove a working blade from a moved BC, one of the non working blades will work.

And the one prevously working one will not.

If we connect the non working blade back into it's original location behind the mcdata, it doesn't work either.

All standalone servers work fine.

This looks like some type of a persistent FCID issue. I have reviewed the white paper for brocade AG mode with Cisco director document.

And removed the id-allocation for the qlogic hbas and that did not provide improved results.

In addition, I have placed calls with Brocade and Cisco and each has reviewed the configuration of their components and will not assist with any inter manufacturer compatibilities.

Any thoughts ?

Re: SAN core migration


it is a problem of the different behaviour of FCID allocation for both vendors. Cisco is assigning adresses in a "first come, first serve" behaviour and these address assignment is persistent. So, only removing the Qlogic id-allocation might not be enough, you have to change the persistent fcid entries that have been already assigned.

The problem is, that the brocade AG is exspecting the whole area for itself. So a frame to the same area will not be forwarded to the Cisco switch, because it should be on the AG. But the MDS might have assigned an address of the same area to another port (your storage). So you will not get any communication between this blade and the storage. You can only assign a static fcid to your blade that do not interfere with the storage address, something like xx.ff.nn, where xx is the domain id and nn an increasing number.

Can you post the show flogi database output to get an idea of the fcids, mostly for the blades and storage ports.

Re: SAN core migration

Hi dochs1,

--->>> In addition, I have placed calls with Brocade and Cisco and each has reviewed the configuration of their components and will not assist with any inter manufacturer compatibilities.

Just my opinion.... it is comprehensible if Brocade will not assist with the Mogration from Brocade to Cisco since they Migrate from -> to, but is not comprehensible that Cisco is not willing to guide your with a Migration as NEW Cisco Client.

But that another story.

Official, newest EOS MicroCode and newest SAN-OS are not supported, this is the principal Big problem.

Another question is here:

--->>> SAN core migration

do your want to migrate the productive McDATA Config  to Cisco ?

Re: SAN core migration

Hi dochs1,

I also need the port for your BC and all storage ports, that are zoned to your blades.
