Issue/Introduction

Not all ESXi hosts in the vSphere cluster are appearing in the list of replicated servers for enhanced replication.

The vSphere Replication appliance is attempting to connect to two management IPs configured on vmk0 and vmk4. A timeout error is seen in the logs when trying to contact the IP address 172.XX.XX.19, which belongs to vmk4 :

2024-11-26 15:29:17.349 INFO  com.vmware.hms.hbr.HbrService [hms-main-scheduled-thread-10] (..hms.hbr.HbrService) [operationID=c70c0e05-a312-4f71-82be-d6b175c7981c-HMSINT-9388] | Get hbrsrvuw info from host-1361951 (host uuid:4f65aa14-113f-11ec-826f-3a68dd5e026f) ...found ipAddresses: [172.XX.XX.19, 10.XX.XX.74]

Environment

vSphere Replication 9.x 

Cause

The vSphere Replication appliance is unable to communicate with an additional VMkernel interface configured with management traffic, apart from the default vmk0 interface.

Resolution

The vSphere Replication appliance retrieves NICs tagged for management traffic, and if it is unable to contact the VMkernel (which may be on the same or a different subnet), it will not add that host to the list of replicated servers available for VM replication.

Ensure there is connectivity between the vSphere Replication appliance and vmkernel interface with management traffic tagged.

Once the connectivity issue is resolved, the host will become available for use with enhanced replication.
