McDATA Fabric Mode to Native Mode

Hi, All,

We are trying to migrate an existing FOS IM2 fabric with all Brocade switches to IM0 (Native Mode). In this, when we change the interop mode of the first switch from IM2 to IM0 will it assume the correct zone configuration form the fabric? (remember this is the first switch and all other switches are at this point in time at IM2, also when we change from IM2 to IM0 switch erases the configuration and restarts.)

or if I ask the same question in a different way is the zone databases compatible between IM0 and IM2?

Cheers,

Max.

Re: McDATA Fabric Mode to Native Mode

Its amazing how many people look at this post and nobody seemed to have interest in leaving a message. I have been digging the Brocade Documentation and no where it says the solution. All what it says it when you change the interopmode to 0 it will assume the zone configuration from the other switches in the fabric. But what is not clear is if all other switches are running at mode 2 will the mode 0 switch assume the zone configuration from mode 2 switches.

Has anyone done migration from McDATA to Brocade, If so you should have faced the same issue when you want to change the mode to native after the last McDATA is left.

Thanks,

Max.

Max,

if you want to Migrate existing EOS Fabric based Switches (formely McDATA ) to Fabric OS based Switches - Brocade - and intend to remain in IM0 in Brocade Native environments , they need here additional Hardware like brocade 7500 / 7800 or appropriate DCX Routing Blade.

Re: McDATA Fabric Mode to Native Mode

  1. Perform a configuration upload
  2. Set the principal switch
  3. Persistent disable all the device ports in Fabric (Not the ISL Ports only the host and storage ports)
  4. Disable the switches in the order edge to core (switchdisable)
  5. Make sure all McDATA switches have been disabled and shutdown (preferably ISLs removed)
  6. Export the zone database – through DCFM export and save the zone database (Offline Backup/Repository .xml file)
  7. Change the mode to native on core switch (interopmode 0) – this will clear the zone database and restart the switch
  8. Import the offline zone database (.xml file) – previously exported (through DCFM)
  9. Set the default zonning mode to noaccess
  10. Activate the zone database – this will perform the checks on the zone database
  11. Check the switch logs and make sure no critical errors
  12. Check and set the Principal switch
  13. Starting from Core to Edge change the mode (interopmode 0) on the remaining switches, this will clear the zone database, restart the switch and assume the zone database from core
  14. Check the switch logs and make sure no errors
  15. Persistent enable all the device ports in Fabric (Not the ISL Ports only the host and storage ports)
  16. Make sure the server paths have been re-established
  17. Perform configuration upload

I have given the above procedure for all of your benefit.
