How do I reinstall SAP HANA when I have existing data, log, and shared volumes?

I'm working on a protection and recovery procedure where I need to recover from a server failure of the local OS boot drives. Ideally I will have a backup image or file backups of the server OS boot volume; however, in the event I don't, how do I reinstall the SAP HANA server. I am trying to test and document how I would recover the SAP HANA database server where I have mountable data, log, and shared volumes of my database and I just need to reinstall the SAP HANA server. My initial thought process was this should be simiple - install the OS, use hdblcm to reinstall the server, reconnect the volumes and reboot. Humm...there isn't an option for that...

Any ideas and thoughts?

I wrote a big answer, but after a while I thought about different solution.

If you have all the files: data, log and shared directories, restore them and run hdblcm and choose option register system. That should work. Use the hdblcm located under /hana/shared/<SID>/hdblcm

Let us know in case of problems.
