Can someone please help me - I am having problems with a DN2500 /disk. I have booted the 2500 diskless to another 2500 and am trying to mount the disk. I have the feeling that the standard mount /dev/wn0a /mtpt is not the correct procedure (I am running 10.2 BSD). Thanks, Charlotte

Take a look at the shell script /etc/mkdsk. It describes how to create the device file for your disk for both the BSD and SYSV environments. /dev/wn0a is (according to my understanding of the shell script) Winchester drive, SCSI controller 0 (ie. the DN2500's single SCSI port), disk 0 (ie. the SCSI unit number of the drive), logical volume 1. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)

Note that the system disk supplied by HP/Apollo is SCSI device 6, not device 0, so you need the wn96a/rwn96a entries in /dev. Note also that SR10.3 fails to build /dev/wn96a properly when you install it - it builds /dev/w996a, which may or may not be the proper item (I have a Hotline call open for over a month on this). I will find out the hard way I guess when my DN2500 disk bites the big one. Note also that the instructions on building /dev/wn96a and /dev/rwn96a from UNIX in the DN2500 manual are utter nonsense (the Aegis commands are correct as far as I can tell, but we don't have Aegis so that ain't a whole lot of good). -- Mike Peterson, System Administrator, U/Toronto Department of Chemistry E-mail: system@alchemy.chem.utoronto.ca Tel: (416) 978-7094 Fax: (416) 978-8775
