Troubleshooting: Removing a Resiliency Manager from a resiliency domain
In some cases you may want to remove a Resiliency Manager node from a resiliency domain.
Before removing a Resiliency Manager node, you should first remove the Resiliency Manager from the resiliency domain using the Leave Domain operation in the Veritas Resiliency Platform web console. Completing this operation ensures that the Resiliency Manager is cleanly decommissioned and that all references to it are removed from the Resiliency Manager database and no longer appear in the web console user interface. The Leave Domain operation has prerequisites that are documented in the procedure topic.
See Removing a Resiliency Manager from a resiliency domain.
The following gives more details for trouble scenarios, for example, if the Resiliency Manager you want to remove is not online or if the operation does not complete successfully.
Unable to bring the Resiliency Manager online | The Leave Domain operation requires that both Resiliency Managers be online. However, if you are unable to bring the Resiliency Manager you want to remove online, there is no problem with leaving it in a down state. The resiliency domain and other infrastructure components continue to function. If an Infrastructure Management Server (IMS) was connected to the Resiliency Manager that was down, the IMS will automatically reconnect itself to another Resiliency Manager in the same domain. In addition, you can add another Resiliency Manager and join it to the domain. |
Unable to complete Leave Domain operation | The Leave Domain operation is a multistep process. First the Resiliency Manager decommissions itself. Then all references to it are removed from the Resiliency Manager database. Finally any IMS connected to the decommissioned Resiliency Manager is rerouted to another Resiliency Manager. You can use the Activities pane to verify that the Leave Domain operation completes. If the process fails before all steps are complete, the partially removed Resiliency Manager no longer operates. However, the resiliency domain continues to function. |
