If you are upgrading to new Brocade FC switches, you must replace the switches in the first fabric, verify that the MetroCluster configuration is fully operational, and then replace the switches in the second fabric.

  • The MetroCluster configuration must be healthy and in normal operation.

  • The MetroCluster switch fabrics consist of four Brocade switches.

    The illustrations in the following steps show current switches.

  • The switches must be running the most recent supported firmware.

  • This procedure is nondisruptive and takes approximately two hours to complete.

  • You need the admin password and access to an FTP or SCP server.

  • Enable console logging before performing this task.

The switch fabrics are upgraded one at a time.

At the end of this procedure, all four switches will be upgraded to new switches.

Steps

  1. Disable the first switch fabric:

    FC_switch_A_1:admin> switchCfgPersistentDisable

    FC_switch_A_1:admin> switchCfgPersistentDisable

  2. Replace the old switches at one MetroCluster site.

    1. Uncable and remove the disabled switch.

    2. Install the new switch in the rack.

    3. Disable the new switches by running the following command on both switches:

      switchCfgPersistentDisable

      FC_switch_A_1:admin> switchCfgPersistentDisable

    4. Cable the new switch using the recommended port assignments.

    5. Repeat these substeps at the partner MetroCluster site to replace the second switch in the first switch fabric.

      Both switches in fabric 1 have been replaced.

  3. Power up the new switches and let them boot up.

  4. Configure the Brocade FC switches using one of the following procedures:

    Configure Brocade FC switches with RCF files

    Configure the Brocade FC switches manually

  5. Save the switch configuration:

    cfgSave

  6. Wait 10 minutes to allow the configuration to stabilize.

  7. Confirm connectivity to the disks by entering the following command on any one of the MetroCluster nodes:

    run local sysconfig -v

    The output shows the disks attached to the initiator ports on the controller, and identifies the shelves connected to the FC-to-SAS bridges:

  8. Returning to the switch prompt, verify the switch firmware version:

    firmwareShow

    The switches must be running the most recent supported firmware.

  9. Simulate a switchover operation:

    1. From any node's prompt, change to the advanced privilege level:
      set -privilege advanced

      You need to respond with “y” when prompted to continue into advanced mode and see the advanced mode prompt (*>).

    2. Perform the switchover operation with the -simulate parameter:

      metrocluster switchover -simulate

    3. Return to the admin privilege level:

      set -privilege admin

  10. Repeat the previous steps on the second switch fabric.

After repeating the steps, all four switches have been upgraded and the MetroCluster configuration is in normal operation.
