Arcserve r12 - Recover with only session files (S0000001.CTF, etc.)

In Arcserve r12.0 SP2 (build 5611), can I do a restore from a session CTF when the header.ctf is lost?

The session files were copied to an external USB drive, but not the header files. I have tried creating a new FSD and running a scan but it comes back with 0 files.

Can anyone offer any ideas on how to get this data recovered?

Can you use Arcserve's "Merge" utility to scan the media and maybe regenerate the associated header.ctf file?  Or at least it would make the database aware of the contents of the backup sessions.  My recollection is a Merge ignores the header.ctf directory file and just looks at sessions.  I may be misremembering though.

The Merge produces the same response as the scan. "E3841 Unable to find session number... EC=BAD PARAMETER PASSED".

If I try either a merge or a scan without the header file, I have to supply a media name. Since these are older backups, I'm not sure what that may be and nothing I have tried works. I've followed some of the other posts I have seen for creating a new FSD, running a job, stop the tape engine, move the CTF files in, start tape engine and then try scan or merge.

All fail with the same result.

It cost $199 for CA support, but here is the answer:

1)Created a new FSD and copied the session file to it (S0000002.CTF)

2)Had to set Administrator to be system account in Arcserve before running the next command

3)Run ca_devmgr -regenerate 5 3 0 "tape"
Note: The "5 3 0" are the numbers from the FSD's Board, SCSI ID and LUN (e.g Device:8=Board:5,Bus:0,SCSI ID:3,LUN:0).

4)run a Merge job against the session file with the regenerated header
