Removing a Resiliency Manager from a resiliency domain
A Veritas Resiliency Platform resiliency domain typically contains two Resiliency Managers. You can remove a Resiliency Manager from the domain as long as another remains online.
Removing a Resiliency Manager is necessary, for example, if you need to do the following:
Change the host name or IP address of the Resiliency Manager virtual appliance.
Change a virtual appliance that is both a Resiliency Manager and Infrastructure Management Server (IMS) so that it is used only as an IMS.
Note:
Ensure that you meet the prerequisites listed in the procedure.
For example, if you want to decommission a Resiliency Manager virtual appliance node, you do the following steps:
If the virtual appliance node that you want to decommission is configured as both a Resiliency Manager and Infrastructure Management Server (IMS), first remove the IMS from the resiliency domain.
See Removing an IMS.
Remove the Resiliency Manager from the resiliency domain using the Leave Domain procedure below.
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.
If there is an IMS on a separate node that was reporting to the Resiliency Manager, ensure that it is reconnected to another Resiliency Manager.
To remove a Resiliency Manager from a resiliency domain
- Prerequisites
Both Resiliency Managers must be online.
Perform the operation from the Resiliency Manager that is remaining in the resiliency domain, not from the Resiliency Manager that is being removed.
You should perform the operation during a maintenance window and send appropriate notifications in advance.
Ensure that no activity is occurring on the Resiliency Manager that you plan to remove. For example, ensure that no workflow is in progress.
- Navigate
Settings (menu bar) > Infrastructure > Details View
- Expand the data center, locate the Resiliency Manager, and do the following:
Select the vertical ellipsis icon next to the Resiliency Manager and select Leave Domain.
The operation can take over five minutes to complete as it is a multistep process.
- Once the operation is successfully completed, you can remove the Resiliency Manager virtual appliance node using the appropriate hypervisor manager.
