Monitoring the MetroCluster configuration

You can use ONTAP MetroCluster commands and Unified Manager for DM Series to monitor the health of a variety of software components and the state of MetroCluster operations.

  • Checking the MetroCluster configuration
    You can check that the components and relationships in the MetroCluster configuration are working correctly. You should do a check after initial configuration and after making any changes to the MetroCluster configuration. You should also do a check before a negotiated (planned) switchover or a switchback operation.
  • Commands for checking and monitoring the MetroCluster configuration
    There are specific ONTAP commands for monitoring the MetroCluster configuration and checking MetroCluster operations.
  • Detecting failures with Lenovo MetroCluster Tiebreaker software
    The Tiebreaker software resides on a Linux host. You need the Tiebreaker software only if you want to monitor two clusters and the connectivity status between them from a third site. Doing so enables each partner in a cluster to distinguish between an ISL failure, when inter-site links are down, from a site failure.
