During an HCX 4.11 or VCF 9.x bulk migration workflow for an encrypted VM, one of the following validation alerts will be seen if the Host Based Replication agent vSphere Installation Bundle (HBR agent VIB) is not installed on the source ESXi host.
"HBR-agent is not installed on source ESXi host for encrypted VM migration"
"HBR-agent is installed but not running on source ESXi host, running state is required for encrypted VM migration"
The HBR agent VIB must be manually installed on the ESXi host in order to allow HCX bulk migration of an encrypted VM as outlined in the HCX 4.11 release notes.
HCX does not provide any way to install this VIB automatically in order to avoid a potential conflict with the installation of the same VIB on the hosts via vLCM operations.
Note that if the HBR agent VIB is manually installed on a host that is part of a vLCM-managed cluster, and the vLCM cluster image does not include the HBR Agent component, then vLCM will automatically remove the VIB during image remediation or compliance enforcement. To avoid this scenario the HBR agent file can also be imported into vLCM.
Please open a Broadcom support case and refer to this knowledge article in order to get assistance with manually installing the HBR agent VIB.
