I hope you type in mknod "/dev/tape70" c 0 70. I was wondering what block size the tar tape is. MPE can only go up to 16K bytes for a block. Maybe if you specify a 16K block size on the UNIX side, MPE will be able to read. I'm just guessing, but loading tar tapes from UNIX was tested. Rick Ehrhart [log in to unmask]
