I tried all troubleshooting in hyperflex side finally came to know some issue from the vcenter side(for testing we deployed new vcenter and deployment, reregister everything works smoothly on this )
Do you have any info on whats causing the issue on the vcenter end?
Now am going to try to take the backup from vCenter management appliance and restore the inventory and configuration to new vcenter. Is this make any changes? Is it make sense?
You can do this but the configuration may not be restored from windows to appliance completely.
I tried all version of customized CISCO ESXi images (6.0,6.5 and 6.7)
We removed all the MOB entry and EAM entry from vCenter management objects, Postgres DB nodes entries look ok, not sure about any orphaned objects entries available.
Reboot the vCenter, reimage esxi host, clean up UCS multiple times didn't make any changes on deployment failure. (Deployment are working fine with test vCenter with the same version and build)
"You can do this but the configuration may not be restored from windows to appliance completely"
Before Hyperflex upgrade, I migrate the vCenter (6.5)from Windows to VCSA 6.7, delete and rebuild the HX-cluster after this vcenter migration.
