Solution
Ignore this error, or connect to the VAMI by using a supported browser other than Internet Explorer.
vSphere Replication Server Registration Takes Several Minutes
vSphere Replication server registration might take a long time depending on the number of hosts in the
vCenter Server inventory.
Problem
If the vCenter Server inventory contains a few hundred or more hosts, the Register VR Server task takes
more than a few minutes to complete.
Cause
vSphere Replication updates each host's SSL thumbprint registry. The vCenter Server Events pane
displays Host is configured for vSphere Replication for each host as the vSphere Replication
server registration task progresses.
Solution
1 Wait for the registration task to complete.
After it finishes, you can use vSphere Replication for incoming replication traffic.
2 Alternatively, edit /opt/vmware/hms/conf/hms-configuration.xml and change hms-config-
host-at-hbr-threadpool-size parameter to a higher value to enable parallel processing of more
hosts at a time and restart the vSphere Replication management server /etc/init.d/hms restart
Generating Support Bundles Disrupts vSphere Replication
Recovery
If you generate a vSphere Replication log bundle and at the same time attempt to run a recovery, the
recovery might fail.
Problem
In heavily loaded environments, generating log bundles can cause vSphere Replication connection
problems during recovery operations. Recovery fails with the error
A generic error occurred in the vSphere Replication Management Server. Exception details: 'Failed
write-locking object: object_ID'.
Cause
vSphere Replication server is blocked when the log bundle is generated. This situation occurs if the
storage for the vSphere Replication virtual machine is overloaded.
