VRAs are uninstalled via the Zerto User Interface and not via the vCenter Server user interface. You cannot uninstall a VRA which is used to protect or recover virtual machines.
For a VRA protecting virtual machines: Before uninstalling the VRA, remove affinity rules for protected virtual machines on the host and vMotion these protected virtual machines to another host in the cluster with a VRA installed.
For a VRA recovering virtual machines: Before uninstalling the VRA, change the host for all virtual machines in VPGs recovering to this VRA to another host, as described in Evacuating a Recovery VRA. A bitmap sync occurs to synchronize the VPGs with the new host.
Note: If the VRA has crashed, or was accidentally deleted, it must be forcibly uninstalled, as described in Handling a VRA in an Error State (Ghost VRA).
For a VRA in a cluster, you can remove it and then install a new VRA. However, to ensure that virtual machines in the cluster are not moved to the host without a VRA from the time the VRA is removed to the time a new VRA is installed, it is recommended to perform the following procedure.
To uninstall a VRA with virtual machines being recovered to it:
|1.||When the VRA to be removed is in a cluster, set VMware DRS to manual for the duration of the procedure, so that virtual machines in the cluster are not moved to the host without a VRA from the time the VRA is removed to the time a new VRA is installed.|
|2.||Remove affinity rules for protected virtual machines on the host and vMotion any protected virtual machines to another host with a VRA installed.|
|3.||Change the host for all virtual machines in VPGs recovering to this VRA to another host, as described in Evacuating a Recovery VRA.|
|4.||Wait for any synchronization to complete.|
|5.||Either select the VRAs to uninstall in the VRAs tab or for a single VRA display the VRA details by clicking the VRA Name link in the VRAs tab, and click MORE > UNINSTALL.|
|6.||Once the VRAs are completely removed, install a new VRA on the host.|
Note: If a VRA cannot be removed, when the VRA was installed on an ESXi version 4.x or 5.x host and the password to the host was changed, contact Zerto support.
After the VRA is uninstalled, connectivity from that VRA to any Zerto Cloud Connector is lost. After a VRA is reinstalled on the host, the ports that were used for the connection to the Zerto Cloud Connector are not reused and new ports must be opened in the firewall for the cloud site. For details about Zerto Cloud Connectors, refer to Zerto Cloud Manager Administration Guide.
