If a standby cell is not running properly, you can recover from the failure by deploying a new standby cell.
If one of the standby cells is in the
Failed state, you can deploy a new cell. To view the state of the cells in the cluster, see View the Status of the Cells in a Database High Availability Cluster.
You can use this workflow to reuse the IP addresses and hostname of the failed standby when you deploy a new standby.
- If possible, use the cell management tool to shut down the vCloud Director process. From the failed standby cell, run the following command.
/opt/vmware/vcloud-director/bin/cell-management-tool -u <admin username> cell --shutdown
- Power off the failed standby VM.
- Remove the failed standby appliance from both the vCloud Director server group and the repmgr high availability cluster. See Unregister a Failed or Unreachable Standby Node in a Database High Availability Cluster.
- If you want to reuse the IP address and DNS name of the failed standby cell, you must ensure that the failed standby remains powered off or delete it.
- Deploy a new standby appliance. You can deploy the appliance by using the vSphere Client or deploy the appliance by using the VMware OVF Tool.
After deploying the new standby, the cluster health must be Healthy.Important: The OVA version of the newly deployed standby must be the same as the existing appliances in the cluster. To view the version of running appliances, see the About information in the appliance management UI. The appliance is distributed with a name of the form VMware Cloud Director-v.v.v.v- nnnnnn_ OVF10.ova, where v. v. v. v represents the product version and nnnnnn the build number. For example: VMware Cloud Director-10.2.0.0-9229800_OVA10.ova.
