Configure The Ontap Mediator Service From A Metrocluster Ip

Di: Amelia

NetApp® MetroCluster is a continuously available storage solution for NetApp ONTAP® running on FAS and AFF systems. MetroCluster IP is the latest evolution that uses an Ethernet-based back-end storage fabric. MetroCluster IP provides a highly redundant configuration to meet the needs of the most critical business applications. Manage ONTAP Mediator, including changing user credentials, stopping and re-enabling the service, verifying its health, and installing or uninstalling SCST for host maintenance. You can also manage certificates, such as regenerating self-signed certificates, replacing them with trusted third-party certificates, and troubleshooting certificate-related issues. If the ONTAP Mediator is down, the metrocluster configuration-settings mediator remove command still prompts you to enter the user name and password for the ONTAP Mediator admin user account and removes the ONTAP Mediator service from the MetroCluster configuration.

Configuring the clusters into a MetroCluster configuration You must peer the clusters, mirror the root aggregates, create a mirrored data aggregate, and then issue the command to implement the MetroCluster operations.

Refresh a four-node or an eight-node MetroCluster IP configuration ...

You can use either the ONTAP Mediator-assisted automatic unplanned switchover (MAUSO) in the MetroCluster IP configuration or you can use the MetroCluster Tiebreaker software. It is not required to use the MAUSO or Tiebreaker software; however, if you choose to not use either of these services, you must perform a manual recovery if a disaster occurs. Monitoring the MetroCluster configuration You can use ONTAP MetroCluster commands and Active IQ Unified Manager to monitor the health of a variety of software components and the state of MetroCluster operations. Starting with ONTAP 9.7, you can use either the ONTAP Mediator-assisted automatic unplanned switchover (MAUSO) in the MetroCluster IP configuration or you can use the MetroCluster Tiebreaker software.

Description The metrocluster configuration-settings mediator add command configures the connection between the mediator and all the nodes in a MetroCluster configuration. Before this command is run MetroCluster should be configured on all the clusters. Mediator username and password are required to successfully add the mediator.

MetroCluster configurations enhance the built-in high availability and nondisruptive operations of NetApp hardware and ONTAP storage software, providing an

If you are connecting to an existing Tiebreaker or ONTAP Mediator instance, you need the username, password, and IP address of the Tiebreaker or Mediator service. About this task If you must install a new instance of the ONTAP Mediator, Beginning with ONTAP 9.7, you can use either the ONTAP Mediator-assisted automatic unplanned switchover (MAUSO) in the MetroCluster IP configuration or you can use the MetroCluster Tiebreaker software. It is not required to use the MAUSO or Tiebreaker software; however, if you choose to not use either of these services, you must perform a manual

Complete the MetroCluster IP controller upgrade

Complete the automated controller upgrade process by verifying the network reachability and restoring any monitoring configuration. As you plan your MetroCluster IP configuration, you should understand the hardware components and how they interconnect.

Beginning with ONTAP 9.12.1, you can enable the MetroCluster automatic forced switchover feature in a MetroCluster IP configuration. This feature is an extension of the Mediator-assisted unplanned switchover (MAUSO) feature. ONTAP supports layer 3 connectivity using virtual IP (VIP) and Border Gateway Protocol (BGP). The combination VIP and BGP for redundancy in the front-end networking with the back-end MetroCluster redundancy provides a layer 3 disaster recovery solution.

Confirm that the MetroCluster configuration was added properly by using the Tiebreaker CLI monitor show -status command.

MetroCluster® IP Installation and Configuration Guide

Expanding a MetroCluster IP configuration Depending on your ONTAP version, you can expand your MetroCluster IP configuration by adding four new nodes as a new DR group.

Abstract Lenovo® MetroClusterTM is a continuously available storage solution for Lenovo ONTAP® running on Hybrid and AFA systems. MetroCluster IP is the latest evolution that uses an Ethernet-based back-end storage fabric. MetroCluster IP provides a highly redundant configuration to meet the needs of the most critical business applications. Because You must set up each node in the MetroCluster configuration in ONTAP, including the node-level configurations and the configuration of the nodes into two sites. You must also implement the MetroCluster relationship between the two sites.

Restore Tiebreaker or Mediator monitoring After completing the upgrade of the MetroCluster configuration, you can resume monitoring with the Tiebreaker or Mediator utility.
