When adding VxRail hosts to an existing cluster in SDDC Manager, only 1 host is presented for Thumbprint verification despite multiple hosts showing in the previous Discovered Hosts screen.
SDDC Manager 5.x
This is a UI issue with how many hosts are displayed in the Thumbprint Verification screen. This will be resolved in a future release.
This issue is resolved in VMware Cloud Foundation 5.2.2.
To workaround the issue, please add the hosts by API using KB 379202.
