Hi emcmagic

You need the below information:

-  What multi-path software (like PowerPath..), version.  This is the key for path management to affect interruption.

-  MDS 9xxx model, NX-OS version

-  Need licenses for all active ports

Then you can ask local service team to create replacement procedure document with:

I generated a document based on assumed MDS 9148, 5.01a.

Please feel free to contact us for any further question!

Hello Simon,

Would you please attach your document? It seems neglected.

We are using pwoerpath.

It is in primary investigating process, we are not so clear on what model of switches we are going to upgrade to. So, procedures for any model or version will help me out. I have issues to execute that software.

Looking forward your doc or messages further.

Thanks a lot

Hi, as the document is EMC confidential, so please tell me your EMC email address if you are EMC employee, or you can contact one of EMC pre-sales engineer, then I can send the document by email.

Thanks  & best regards!

Or cold somebody please send me a shares public procedure?

I see, could you then send me some non-confidential document on this question?

Dynamox, I agree with you. ISL the switches together or export/import the active zoneset to the new switch.  I wonder if they have a principle/subordinate setup and the MDS' would be the primary switches.  I've done this several times with Cisco and Brocade but sounds like you've got a handle on it.

One thing they really need to make sure is that they have dual paths the whole way.  I'd perform a SAN health check before anything else.

Once you have answered dynamox's question, I also have some procedures that I can provide at a high level, but they are per OS, MPIO software, etc so those types of details are required prior to being able to come up with a procedure since it will affect what has to be done on the OS or multipathing software during each path outage (assuming you are migrating SAN ports one at a time after you ISL your new Cisco's to the fabric). The other alternative is to create a parallel set of new fabrics with the new switches if you are unable to ISL for any reason (code, limitations, etc) - but that would require you having to group hosts and storage ports together and that is much more complex as dynamox mentions above.

i dont' have any procedures written down but i can answer your questions and give you general guidelines. So you are replacing old MDS switches with new MDS switches ? If yes, are you going to ISL them together to make the transition easier or this will be a cold cut-over ? What kind of operating systems/applications ?

Hey, Simon. It’s me, Jeff. This is my personal email. I switched to this when I left EMC in March.

echolaughmk,

If you could please send me the one you have that would be very helpful, since I can figure out information from it to apply into our case here.
