Change the vendor or model of an FC switch
You might need to to change the vendor of an FC switch from Cisco to Brocade or vice versa, change the switch model, or change both.
-
This procedure applies when you are using NetApp validated switches.
-
You must perform the steps in this procedure on one Fabric at a time, for both Fabrics in the configuration.
-
Check the health of the configuration.
-
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
-
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.
-
Check that the MetroCluster components are healthy:
metrocluster check run
cluster_A::> metrocluster check run Last Checked On: 10/1/2014 16:03:37 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.
-
Check that there are no health alerts:
system health alert show
-
-
Configure the new switch before installation.
Follow the steps in Configure the FC switches.
-
Disconnect the connections from the old switch by removing the connections in the following order:
-
If the local cluster interfaces are connected to a switch:
-
Disconnect the local cluster interfaces
-
Disconnect the local cluster ISLs
-
-
Disconnect the MetroCluster FC interfaces.
-
Disconnect the MetroCluster ISLs.
-
-
Power off the old switch, remove the cables, and physically replace the old switch with the new switch.
-
Cable the switches in the following order:
You must follow the steps in Install and cable the MetroCluster components.
-
Cable the ISLs to the remote site.
-
Cable the MetroCluster FC interfaces.
-
Cable the local cluster interfaces.
If the local cluster interfaces are connected to a switch:
-
Cable the local cluster interfaces.
-
Cable the local cluster ISLs.
-
-
-
Power up the switch.
-
Verify that the MetroCluster configuration is healthy by repeating Step 1.
-
Repeat Step 1 to Step 7 for the second Fabric in the configuration.
