We have a problem writing to our SCSI 5.25 flex via pcdsk(1). I realize
pcdsk is an unsupported utility, this means we are SOL if NCR doesn't
know of an answer offhand. Pcdsk works just fine on MSC based flex drives,
however it does not work for SMSC and HPMSC (SCSI) based flex drives. On
our Tower 32/650 in the /etc/RELDEF directory, the following text can be
found in the file 3.00.00.rd:
The pcdsk(1) command does not operate on the SCSI
floppy disks. This is due to the pcnodes(1) command not
creating the correct nodes. The following are the correct
nodes for the SCSI floppy disk:
/dev/pcdsk/h1s8 major no. 12, minor no. 232
/dev/pcdsk/h1s9 major no. 12, minor no. 236
/dev/pcdsk/h2s8 major no. 12, minor no. 200
/dev/pcdsk/h2s9 major no. 12, minor no. 204
/dev/pcdsk/t80h1s8 major no. 12, minor no. 224
/dev/pcdsk/t80h1s9 major no. 12, minor no. 228
/dev/pcdsk/t80h2s8 major no. 12, minor no. 192
/dev/pcdsk/t80h2s9 major no. 12, minor no. 196
It only works on the MSC floppy. This is an unsupported
command.
Hmmmm. the nodes mentioned here yeild no joy when created with mknod(1),
pcdsk complains that it can't open /dev/pcdsk/h2s9. I do know of some
nodes that work, they are as follows:
/dev/pcdsk/h2s8 major no. 64, minor no. 200
/dev/pcdsk/h2s9 major no. 64, minor no. 204
These seem to work, we can get a directory of the flex via pcdsk,
and can transfer files from MSDOS to UNIX via the pcdsk mtu command.
However, when we attempt writing to the flex via the pcdsk utm command
the flex drive light goes on and pcdsk appears to be copying the file
to the flex. After the copy completes, the pcdsk dir command reveals the
file was never really copied to the disk. Is this a problem with the
pcdsk utility itself, or does it lie at the driver level ? If it is in
pcdsk, I can take a stab at porting the PD mtools package over to the
Tower or something. If the problem is elsewhere, I'm SOL. Is anyone
else aware of this problem or a solution to it ??

Art, I have successfully ported and used MTOOLS with SCSI to TOWER. I'll e-mail you a copy. Like PCDSK, MTOOLS are unsupported. Robert Heath

I found that the "utm" will sometimes core dump when copying several files at a time. The solution to this is to do a "dir" as the first command after pcdsk has been run, then do the "utm". ---cut-here---------------------------------------------------------- # Copyright 1988 NCR Corporation - Dayton, Ohio, USA # @(#)cmd/pcdsk:pcnodes.sh 1.1 # # Shellscript to make device nodes to recognize PC disks. echo "Making device nodes for PC disks" if [ ! -d /dev/pcdsk ] then echo "Creating directory '/dev/pcdsk' to contain device nodes" mkdir /dev/pcdsk chmod 755 /dev/pcdsk fi echo "Raw PC -- 40 tracks, 1 side, 8 sectors per track ... /dev/pcdsk/h1s8" /etc/mknod /dev/pcdsk/h1s8 b 2 162 chmod 666 /dev/pcdsk/h1s8 echo "Raw PC -- 40 tracks, 1 side, 9 sectors per track ... /dev/pcdsk/h1s9" /etc/mknod /dev/pcdsk/h1s9 b 2 178 chmod 666 /dev/pcdsk/h1s9 echo "Raw PC -- 40 tracks, 2 sides, 8 sectors per track ... /dev/pcdsk/h2s8" /etc/mknod /dev/pcdsk/h2s8 b 2 34 chmod 666 /dev/pcdsk/h2s8 echo "Raw PC -- 40 tracks, 2 sides, 9 sectors per track ... /dev/pcdsk/h2s9" /etc/mknod /dev/pcdsk/h2s9 b 2 50 chmod 666 /dev/pcdsk/h2s9 echo "Raw PC -- 80 tracks, 1 side, 8 sectors per track ... /dev/pcdsk/t80h1s8" /etc/mknod /dev/pcdsk/t80h1s8 b 2 130 chmod 666 /dev/pcdsk/t80h1s8 echo "Raw PC -- 80 tracks, 1 side, 9 sectors per track ... /dev/pcdsk/t80h1s9" /etc/mknod /dev/pcdsk/t80h1s9 b 2 146 chmod 666 /dev/pcdsk/t80h1s9 echo "Raw PC -- 80 tracks, 2 sides, 8 sectors per track ... /dev/pcdsk/t80h2s8" /etc/mknod /dev/pcdsk/t80h2s8 b 2 2 chmod 666 /dev/pcdsk/t80h2s8 echo "Raw PC -- 80 tracks, 2 sides, 9 sectors per track ... /dev/pcdsk/t80h2s9" /etc/mknod /dev/pcdsk/t80h2s9 b 2 18 chmod 666 /dev/pcdsk/t80h2s9 ls -ls /dev/pcdsk/* ---cut-here---------------------------------------------------------- -- Tim.Nelson@Canada.NCR.COM - or - Tim.Nelson@Canada.NCR.CA NCR Canada, Customer Support Services (416) 819-4112
