Thanks so much for your nuggets of wisdom !
The comments on the CONFIG group files being on LDEV=1 are great !
The primary path is not going to change (they are all SCSI connected, and I am swapping the SCSI id's when I swap the drives).
One question, when I restore with the DIRECTORY option, does this make sure that the access rights, capabilities, limits, etc. are the same as before ? (That was why I was using BULDJOB1).
