Active and Standby Node Failure - Unplanned

When both the Active and Standby node fails in a SMI Cluster Manager HA model, you can redeploy the SMI Cluster Manager in HA mode using the Inception Server. To redeploy the SMI Cluster Manager HA using the Inception Server, use the following procedure:

  1. Log in to the Inception Server CLI and perform a cluster synchronization.

    clusters cluster_name actions sync run debug true 

    Example:

    SMI Cluster Deployer# clusters trysjc-ha actions sync run debug true
    This will run sync.  Are you sure? [no,yes] yes
    message accepted
    Note

    In the event of an unplanned outage, you cannot restore the data since the SMI does not backup data periodically in the background. However, in the event of planned maintenance, you can restore the data from the storage node manually. You can restore the data using the scp command on the storage node:

    scp -i ../test_key2.pem -r host_name@<ipv4address>:/data 
  2. Copy the backed up data from the storage node and verify whether the NFs, CM and CEE configurations are present.

    Note

    Restore the backed up data only when the Active and Standby nodes and all the pods within these nodes are up and running.

NOTES:

  • clusters cluster_name - Specifies the K8s cluster.

  • actions sync run debug true - Synchronizes the cluster configuration.
