You must refresh the MetroCluster configuration when expanding it from a two-node configuration to a four-node configuration.

Steps

  1. Refresh the MetroCluster configuration:

    1. Enter advanced privilege mode:
      set -privilege advanced

    2. Refresh the MetroCluster configuration:
      metrocluster configure -refresh true -allow-with-one-aggregate true

      The following command refreshes the MetroCluster configuration on all of the nodes in the DR group that contains controller_A_1:

      controller_A_1::*> metrocluster configure -refresh true -allow-with-one-aggregate true

[Job 726] Job succeeded: Configure is successful.

    3. Return to admin privilege mode:

      set -privilege admin

  2. Verify the networking status on site A:

    network port show

    The following example shows the network port usage on a four-node MetroCluster configuration:

    cluster_A::> network port show
                                                          Speed (Mbps)
Node   Port      IPspace   Broadcast Domain Link   MTU    Admin/Oper

       e0b       Cluster   Cluster          up     9000  auto/1000

       e0f       Default   Default          up     1500  auto/1000
       e0g       Default   Default          up     1500  auto/1000

       e0a       Cluster   Cluster          up     9000  auto/1000

       e0d       Default   Default          up     1500  auto/1000
       e0e       Default   Default          up     1500  auto/1000
       e0f       Default   Default          up     1500  auto/1000
       e0g       Default   Default          up     1500  auto/1000

  3. Verify the MetroCluster configuration from both sites in the MetroCluster configuration.

    1. Verify the configuration from site A:

      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. Verify the configuration from site B:

      metrocluster show

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

    3. Verify that the DR relationships have been created correctly:

      metrocluster node show -fields dr-cluster,dr-auxiliary,node-object-limit,automatic-uso,ha-partner,dr-partner

      metrocluster node show -fields dr-cluster,dr-auxiliary,node-object-limit,automatic-uso,ha-partner,dr-partner
dr-group-id cluster     node    ha-partner dr-cluster  dr-partner   dr-auxiliary  node-object-limit automatic-uso

4 entries were displayed.
