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 Web Client, select the vCenter Server instance and click Manage > Settings >
Advanced Settings to check that the VirtualCenter.FQDN key is set to either a fully qualified
domain name or to a literal address.
2 Use a supported browser to log in to the vSphere Replication VAMI.
The URL for the VAMI is https://vr-appliance-address:5480.
3 Review and confirm the browser security exception, if applicable, to proceed to the login page.
4 Type the root user name and password for the appliance.
You configured the root password during the OVF deployment of the vSphere Replication appliance.
5 Enter the same FQDN or literal address for vCenter Server as you set for the VirtualCenter.FQDN
key.
6 Click Save and Restart Service to apply the changes.
Scalability Problems when Replicating Many Virtual Machines with
a Short RPO to a Shared VMFS Datastore on ESXi Server 5.0
Performance might be slow if you replicate a large number of virtual machines with a short Recovery
Point Objective (RPO) to a single virtual machine file store (VMFS) datastore that is accessible by
multiple hosts on the recovery site.
Problem
This problem occurs when running ESXi Server 5.0 on the recovery site. It can result in missed RPO
targets.
The number of virtual machines that can successfully replicate to a single, shared VMFS datastore
increases if the RPO targets are longer.
Follow the guidelines when calculating the number of virtual machines that you should replicate to a
single VMFS volume on the recovery site.
n
If all your virtual machines have an RPO of 15 minutes, performance is affected when replicating 50
to 100 virtual machines to the same VMFS datastore.
