Verifying the health of the MetroCluster configuration

Contributors netapp-ranuk Download PDF of this page

You must verify the health and connectivity of the MetroCluster configuration prior to performing the transition

  1. Verify the operation of the MetroCluster configuration in ONTAP:

    1. Check whether the system is multipathed:node run -node node-name sysconfig -a

    2. Check for any health alerts on both clusters: system health alert show

    3. Confirm the MetroCluster configuration and that the operational mode is normal: metrocluster show

    4. Perform a MetroCluster check: metrocluster check run

    5. Display the results of the MetroCluster check: metrocluster check show

    6. Check for any health alerts on the switches (if present): storage switch show

    7. Run Config Advisor.

    8. After running Config Advisor, review the tool’s output and follow the recommendations in the output to address any issues discovered.

  2. Verify that the cluster is healthy: cluster show

    cluster_A::> cluster show
    Node           Health  Eligibility   Epsilon
    -------------- ------  -----------   -------
    node_A_1_FC    true    true          false
    node_A_2_FC    true    true          false
    
    cluster_A::>
  3. Verify that all cluster ports are up: network port show -ipspace cluster

    cluster_A::> network port show -ipspace cluster
    
    Node: node_A_1_FC
    
                                                      Speed(Mbps) Health
    Port      IPspace      Broadcast Domain Link MTU  Admin/Oper  Status
    --------- ------------ ---------------- ---- ---- ----------- --------
    e0a       Cluster      Cluster          up   9000  auto/10000 healthy
    e0b       Cluster      Cluster          up   9000  auto/10000 healthy
    
    Node: node_A_2_FC
    
                                                      Speed(Mbps) Health
    Port      IPspace      Broadcast Domain Link MTU  Admin/Oper  Status
    --------- ------------ ---------------- ---- ---- ----------- --------
    e0a       Cluster      Cluster          up   9000  auto/10000 healthy
    e0b       Cluster      Cluster          up   9000  auto/10000 healthy

  4. Verify that all cluster LIFs are up and operational: network interface show -vserver cluster

    Each cluster LIF should display "true" for "Is Home" and "up/up" for "Status Admin/Oper".

    cluster_A::> network interface show -vserver cluster
    
                Logical      Status     Network          Current       Current Is
    Vserver     Interface  Admin/Oper Address/Mask       Node          Port    Home
    ----------- ---------- ---------- ------------------ ------------- ------- -----
    Cluster
                node_A-1_FC_clus1
                           up/up      169.254.209.69/16  node_A-1_FC   e0a     true
                node_A_1_FC_clus2
                           up/up      169.254.49.125/16  node_A_1_FC   e0b     true
                node_A_2_FC_clus1
                           up/up      169.254.47.194/16  node_A_2_FC   e0a     true
                node_A_2_FC_clus2
                           up/up      169.254.19.183/16  node_A_2_FC   e0b     true
    
    4 entries were displayed.

  5. Verify that auto-revert is enabled on all cluster LIFs: network interface show -vserver Cluster -fields auto-revert

    cluster_A::> network interface show -vserver Cluster -fields auto-revert
    
              Logical
    Vserver   Interface     Auto-revert
    --------- ------------- ------------
    Cluster
               node_A_1_FC_clus1
                            true
               node_A_1_FC_clus2
                            true
               node_A_2_FC_clus1
                            true
               node_A_2_FC_clus2
                            true
    
        4 entries were displayed.
