vSphere Replication Service Fails with Unresolved Host Error
If the address of vCenter Server is not set to a fully qualified domain name (FQDN) or to a literal address,
the vSphere Replication service can stop unexpectedly or fail to start after a reboot.
Problem
The vSphere Replication service stops running or does not start after a reboot. The error unable to resolve
host: non-fully-qualified-name appears in the vSphere Replication logs.
Solution
1 In the vSphere Client, select Administration > vCenter Server Settings > Advanced Settings and check
that the VirtualCenter.FQDN key is set to either a fully qualified domain name or to a literal address.
2 Connect to the VAMI of the vSphere Replication appliance in a Web browser.
The URL for the VAMI is https://vr-appliance-address:5480.
You can also access the VAMI by clicking Configure VR Appliance in the Summary tab in the
vSphere Replication view of the SRM interface.
3 Enter the same FQDN or literal address for vCenter Server as you set for the VirtualCenter.FQDN key.
4 Click Save and Restart Service to apply the changes.
Increase the Memory of the vSphere Replication Server for Large
Deployments
If you deploy an additional vSphere Replication server, you might need to increase the memory of the
vSphere Replication server if that server manages large numbers of virtual machines.
Problem
vSphere Replication supports a maximum of 100 virtual machines per vSphere Replication server.
Replication of more than 100 virtual machines on a single vSphere Replication server can cause memory
swapping on the vSphere Replication server, which affects performance.
Solution
For deployments that exceed 100 virtual machines per vSphere Replication server, increase the RAM of the
vSphere Replication server virtual machine from the default of 512MB to 1GB.
Alternatively, deploy additional vSphere Replication servers and balance the replication load accordingly.
vSphere Replication Appliance Extension Cannot Be Deleted
If you delete the vSphere Replication appliance virtual machine, the virtual appliance management interface
(VAMI) is not available to delete the appliance extension that still exists in vCenter Server.
Problem
Deleting the vSphere Replication appliance does not remove the vSphere Replication extension from
vCenter Server.
Solution
1 Use the Managed Object Browser (MOB) to delete the vSphere Replication extension manually.
2 Redeploy the appliance and reconfigure the replications.
