Go to SolutionChanging Brocade DS200B with DS-5100B switch
Hi,
To get more ports we intend to change 2 brocade DS200B (redundent) with
2 DS5100B, what is the best way to proceed for a configuration with many
servers running (but can be stopped during the night).
Thanks for answer

It depends on. Here are some questions:
Use the server multipathing software?!
What storage system are connect?!
Is there one fabric or two fabrics?!
What type of zoning is used (port/wwn based?!- Thanks for your answer,
These are the answers to yoiur questions :
-Multipathing : 2 servers uses Powerpath, the others MPIO (all Solaris)
-Storage : They are connected to CX3 10C will be migrated later on to CX4 240
-Is there one or 2 fabrics : 1 fabric
-Type of zoning : WWN based

ok, that`s look fine.
Two more questions:
Will you still run with 1 fabric?
So, all server use multipathing?andreas.scht

Then I think it`s easy.
Connect your new 5100 to your currunt environment and get them into your fabric. So Domain ID have to be unique and no zoning have been done on new switches.
After that you could move second path per server and FA Port of CX to new switches. After this you could move first path to new switches. But first look which pathes are active!! I would choose standby path to move and then change standby to active path and move "new" standby path... Last you have to move principal switch to a new one.
I think that`s it... Could somebody verify this procedure?!Hello,
I come back to this issue because the switch migration was postponed,
please how to ISL switches ?
What do you think about uploading switch configuration, stopping everything
and disconnecting the old switch, then downloading the configuration into
the new switch, connecting then starting everything again ?
The servers are running Solaris with MPIO as multipathing, any precaution
to take ?
Thanks

I'm not sure what you are referring to as 'Register' and 'deregister'. From what you have described you just need to move the physical connections from the hosts and storage to the switches from the old ones to the new ones while all the switches are ISLed together.
So steps would be like this:
* ISL the 5100B switches together
* ISL the 5100B switches to the 200B switches
* move your host connections from the old switches to the new switches one connection at a time
* move your array connections from your old switches to the new switches one port at a time
* Remove the ISLs between the 200B and 5100B switches
The only thing you may have to worry about is if you have AIX (and I believe HP-UX may have similar problems). AIX specifically can have trouble with end points of SAN connections moving. Unless they are very new and properly configured for Dynamic Tracking, you may need to rescan for new paths and get rid of old paths on your AIX hosts each time you move one of their connections. To be safe you should check the available paths for the AIX hosts each time you touch any of their paths to see if you need to fix something before you move the next connection.
