Well, the clue was found in the tracefile:

---> dsmc i -tracefile=/tmp/trace -traceflag=general,fileops,verbinfo /
where I found the following errors:
where I found the following errors:

11/19/1997 14:07:54.0901 : aixfilio.c(3032): fioGetAttrib: statx error for 
/CDROM, errno = 145

After killing and restart the removable media daemon (mediad), the backup
workes fine like before.
So I think mediad was in some kind of orphan state (you couldn't do
a "ls /CDROM" either) which caused the trouble.

Hope this helpes you,
