Validation Steps :
The following checks confirm that basic configuration is functional:
Forward and reverse DNS lookups resolve correctly for the VLR appliance.
The VLR appliance certificate is configured with a Fully Qualified Domain Name (FQDN).
The appliance is deployed using a short hostname instead of an FQDN.
The VLR appliance is deployed using a short hostname, which does not match the Subject Alternative Name values in the appliance certificate. Because of this mismatch, hostname verification fails during secure communication, causing the Open Live Site Recovery option to remain grayed out.
HMS logs (/var/log/vmware/hms/hms.0000*.log) show hostname verification failures:

DR plugin logs (/var/log/vmware/dr-client-plugin/drplugin.log) report an incorrect hostname:
2025-11-07 12:00:46,996 [dr-config-thread-11] WARN com.vmware.dr.plugin.utils.ConnectionUtils 8cc4a02c-######d247b7 - Problem occurred while checking service status at https://#######vlsr.##.######.local:443/vrmsjava.io.IOException: HTTPS hostname wrong: should be <######vlsr.##.######.local>
The appliance hostname confirms it is using a short name:
root@vlr [ /home/admin ]# hostnamectl Static hostname: shortname Icon name: computer-vm Chassis: vm 🖴 Machine ID: 52ecda3877#########bb2a5d0530ee3 Boot ID: d9244066d###########15dba6a9700d Virtualization: vmwareOperating System: VMware Photon OS/Linux Kernel: Linux 6.1.147-3.ph5 Architecture: x86-64 Hardware Vendor: VMware, Inc. Hardware Model: VMware7,1Firmware Version: VMW71.00V.23553139.B64.2403260936 Firmware Date: Tue 2024-03-26
The issue resolves by updating the VLR appliance hostname to its FQDN.
# hostnamectl set-hostname FQDN
/etc/hostname file reflects the updated FQDN.
