Hello Richard,
first, thanks for your interest and your friendly help :-)

Yes, a backupversion must exist before they are eligibile for automatic
migration. But this option is true for all files in the filesystem.

We don't use Unix-ACL's. The hsm-filesystem is exported via nfs and there is
only one User ( one program) who use this exported filesystem.

I tested this with only the two files above. So i don't know if the I tested
this with only the two files above. So i don't know if the test-results are
representative for all migrated and premigrated files in the filesystem.

Markus - I can think of two possibilities...
1. The files had been backed up before they migrated.
In this case, when the Backup occurred, they were ordinary files and were
backed up that way. In the absence of a stub file in the backup storage
pool, the whole file has to be restored.
2. The files are using Unix ACLs.
Page 52 of the latest HSM manual make the blanket statement that files with
ACLs are always fully restored.
A much less probable cause might be having RESToremigstate No in your client
options file and TSM erroneously observing that instead of the
-RESToremigstate=Yes specification on the command line; but I doubt it.
(However, if one omitted it from the command line, assuming that the Yes
