Hi
>> 7. Boot client PC.
When user is booting client for PTD; BMR discovers given client (NW, DISK, MSD etc) and sends this discoverd client information to the master server.
In your case, looking at "failed to retrieve any configurations from the server" error message, looks like BMR client in restore environemtn is failing to contact BMR Master server.
This could be happening because the new HW you are discovering has some NW card for which driver is not default available in the SRT. Hence NW communication might not be happening.
BMR on successful discovery of client machine, shows a message box stating discovery is done successfullly. Now user can see the discovered configuration in master admin gui under discovered config menu. Next further steps like initialization of config using this discovered one; mapping; PTR; client boot for restore come (like shown in the video).
You are following the steps but some issue is there related to NW setting. And driver related problem is a high possibility.
I WOULD RECOMMEND YOU TO OPEN A SERVICE TICKET ON THIS TO QUICKLY GET A SOLUTION. BECAUSE ANALYSING THIS NEEDS SOME LOGS, CONFIG ETC DETAILS.
>> 2. Is it possible to restore a BMR backed up client that has 3 hard drives to another machine that has just one hard drive. (please consider this scenario for both clients in the same HW family and also for dissimilar clients).
Yes, this is absolutely supported use case. Dissimilar Disk Restore and Dissimilar System Restore are BMR special features.
Thanks.
