You might need to to change the vendor for FC switches from Cisco to Brocade or vice versa, change the switch model, or change both.

About this task

  • This procedure applies when you are using NetApp validated switches.

  • Enable console logging before performing this task.

  • You must perform the steps in this procedure on one Fabric at a time, for both Fabrics in the configuration.

Steps

  1. Check the health of the configuration.

    1. Check that the MetroCluster is configured and in normal mode on each cluster: metrocluster show

      cluster_A::> metrocluster show
Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_A         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain auso-on-cluster-disaster
Remote: cluster_B         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain auso-on-cluster-disaster

    2. Check that mirroring is enabled on each node: metrocluster node show

      cluster_A::> metrocluster node show
DR                           Configuration  DR
Group Cluster Node           State          Mirroring Mode
----- ------- -------------- -------------- --------- --------------------
1     cluster_A
              node_A_1       configured     enabled   normal
      cluster_B
              node_B_1       configured     enabled   normal
2 entries were displayed.

    3. Check that the MetroCluster components are healthy: metrocluster check run

      cluster_A::> metrocluster check run

Component           Result
------------------- ---------
nodes               ok
lifs                ok
config-replication  ok
aggregates          ok
4 entries were displayed.

Command completed. Use the "metrocluster check show -instance" command or sub-commands in "metrocluster check" directory for detailed results.
To check if the nodes are ready to do a switchover or switchback operation, run "metrocluster switchover -simulate" or "metrocluster switchback -simulate", respectively.

    4. Check that there are no health alerts: system health alert show

  2. Configure the new switches before installation.

    Follow the steps in Configure the FC switches.

  3. Disconnect the connections from the old switches by removing the connections in the following order:

    1. Disconnect the MetroCluster FC and FCVI interfaces.

    2. Disconnect the ATTO FibreBridge bridges.

    3. Disconnect the MetroCluster ISLs.

  4. Power off the old switches, remove the cables, and physically replace the old switches with the new switch.

  5. Cable the switches in the following order:

    You must follow the steps in Cabling a fabric-attached MetroCluster configuration.

    1. Cable the ISLs to the remote site.

    2. Cable the ATTO FibreBridge bridges.

    3. Cable the MetroCluster FC and FCVI interfaces.

  6. Power up the switches.

  7. Verify that the MetroCluster configuration is healthy by repeating Step 1.

  8. Repeat Step 1 to Step 7 for the second Fabric in the configuration.
