HP-UX SCSI hints: On HP-UX 9.x you need gcc. On newer releases, you may compile with the HP ANSI C-Compiler using make CCOM=cc To compile with the free K&R C-compiler call: gmake CCOM=cc 'COPTS= ' or smake CCOM=cc 'COPTS= ' Note that there are no device nodes for userland SCSI on HP-UX, you have to call the included shell script MKNOD.hpux first. If you own a HP-9000-800 series machine, you need to install the file MKNOD.hpux-800 in the /etc init shell script directory in order to call it after each boot. This script will create the files in /dev/scsi/... and /dev/rscsi/... The permissions will be set to read/write for root only. HP does not handle CD-ROMs as well as it should. On the HP have a look at the man pages for pfs pfsd pfs_mount and anymore that they refer too.
