Hi. I seem to recall this being posted before, but I'll ask again- does anybody know the major/minor device numbers for a TMSCP style tape drive (on a VAX, 4.3BSD)? Actually, its not a tape but a WORM disk imitating one, but that shouldn't make any difference at all. Thanks a lot, Eric Volpe ...decvax!yale!spock!eric phone: (203) 281-0690 USMAIL: 42 October Hill Rd. Hamden CT 06518

From ours, which is mtXinu 4.3+NFS: bdevsw: { tmscpopen, tmscpclose, tmscpstrategy, tmscpdump, /* 15 */ 0, B_TAPE }, cdevsw: tmscpopen, tmscpclose, tmscpread, tmscpwrite, /* 38 */ tmscpioctl, nodev, tmscpreset, 0, seltrue, nodev, So our major number is 15 for the block device and 38 for the raw device; your major numbers will probably be the same, but it's a good idea to check. The minor number will presumably be 0, 4, 8, or 12 for /dev/[r]mt0, /dev/[r]mt4, /dev/[r]mt8, or /dev/[r]mt12. > Actually, its not a tape but a WORM disk imitating one, but that > shouldn't make any difference at all. As long as it uses the same driver, no. And I believe that driver can be used by anything that speaks tmscp. der Mouse uucp: mouse@mcgill-vision.uucp arpa: mouse@larry.mcrcim.mcgill.edu
