Implementing the MetroCluster configuration

You must run the metrocluster configure -refresh true command to start data protection on the nodes that you have added to a MetroCluster configuration.

About this task

You issue the metrocluster configure -refresh true command once, on one of the newly added nodes, to refresh the MetroCluster configuration. You do not need to issue the command on each of the sites or nodes.

The metrocluster configure -refresh true command automatically pairs the two nodes with the lowest system IDs in each of the two clusters as disaster recovery (DR) partners. In a four-node MetroCluster configuration, there are two DR partner pairs. The second DR pair is created from the two nodes with higher system IDs.

Steps

  1. Refresh the MetroCluster configuration:

    1. Enter advanced privilege mode:

      set -privilege advanced

    2. Refresh the MetroCluster configuration on one of the new nodes:
      metrocluster configure -refresh true

      The following example shows the MetroCluster configuration refreshed on both DR groups:

      controller_A_2::*> metrocluster configure -refresh true

[Job 726] Job succeeded: Configure is successful.
      controller_A_4::*> metrocluster configure -refresh true

[Job 740] 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)

  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

Configuration: IP fabric

Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_A         Configuration state configured
                          Mode                normal
Remote: cluster_B         Configuration state configured
                          Mode                normal

    2. Verify the configuration from site B:
      metrocluster show

      cluster_B::> metrocluster show

Configuration: IP fabric

Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_B         Configuration state configured
                          Mode                normal
Remote: cluster_A         Configuration state configured
                          Mode                normal
