• Recovering Virtual Machine Manager

    VMM plays a key role in managing the hosts and VMs in the CPS environment. If you have exhausted all options to try to recover from application failure, you can use DPM to recover the VMM database to an older point in time.

    To recover the VMM database, complete the following steps:
    1. From the console VM, open Failover Cluster Manager.

    2. Connect to the management cluster.

    3. Shut down the two VMM VMs (-VMM-01, -VMM-02) that are located on the management cluster.

    4. Use the steps in the section "Recovering a database to its original location" to recover the VMM database (called VirtualManagerDB in SCSHAREDDB SQL Server instance). To minimize data loss, be sure to select the latest recovery point.

    5. Open Failover Cluster Manager, and connect to the management cluster.

    6. Start the VMM VMs.

    7. In the VMM console, verify that the content in the Fabric workspace is updated.

    8. Detect and repair any data consistency issues by following the required steps in the “How to use data consistency runbooks” section in the CPS Admin Guide.

    To recover the VMM VMs, complete the following steps:
    1. From the console VM, open Failover Cluster Manager.

    2. Connect to the management cluster.

    3. Shut down the two VMM VMs (-VMM-01, -VMM-02) that are located on the management cluster.

    4. Use the steps in the "Recovering VMs to their original location" section to recover the VMM VMs. To minimize data loss, be sure to select the latest recovery point.

    5. In Failover Cluster Manager, connect to the management cluster, and then click Roles. In the Roles pane, right-click each VMM VM, and then click Start.

    6. In Failover Cluster Manager, connect to the VMM guest cluster -HA-VMM, and then click Roles. If the -HA-VMM clustered role is not running, right-click the role, and then click Start Role.

    7. Detect and repair any data consistency issues by following the required steps in the “How to use data consistency runbooks” section in the CPS Admin Guide.
