This morning I added an extra HD and a tape drive
to my DEC 200, running DU 4.0 b.
I was very happy to see that the peripherals were
automatically detected. Startup messages were :
duck vmunix: rz0 at scsi0 target 0 lun 0 (LID=0) (QUANTUM FIREBA
LL_TM2110S 300N)
duck vmunix: tz4 at scsi0 target 4 lun 0 (LID=1) (WangDAT Model
3400DX     125F)
Jul 15 23:39:02 duck vmunix: rz6 at scsi0 target 6 lun 0 (LID=2) 
(SEAGATE ST32151N         0328)
I then did the following to create the filesystem on the disk :
1) created the special device files for the disk :
   # cd /dev 
   # ./MAKEDEV rz6
   MAKEDEV: special file(s) for rz6: 
2) placed a label on the disk :
   # disklabel -w -r rz6 SWXCR
   # disklabel -e rz6
  (I guess this uses the SCSI controller to automatically work out
  the disktab data for the seagate HD.)
3) created a new file system :
   # newfs /dev/rrz6c 
4) mount the file system :
   # mkdir /disk2
   # /sbin/mount /dev/rz6c /disk2
   Now, this works as df shows :
   # df -k
   Filesystem  1024-blocks        Used   Available Capacity  Mounted on
   /dev/rz0a         63335       35593       21408    63%    /
   /proc                 0           0           0   100%    /proc
   /dev/rz0g        901949      761687       50067    94%    /usr
   /dev/rz6c       2030059           1     1827052     1%    /disk2
5) Add the File system to /etc/fstab :
   /dev/rz0a        /      ufs rw 1 1
   /proc            /proc  procfs rw 0 0
   /dev/rz0g        /usr   ufs rw 1 2
   /dev/rz0b        swap1  ufs sw 0 2
   /dev/rz6c        /disk2 ufs rw 1 3
   
So, it appears to work OK but I'm surprised at how little trouble
this was ... which makes me suspect I've screwed up somewhere.
Also :
I think I should have added more swap space instead of assigning
the whole disk to data. So, I think I could recreate the filesystems 
on this new HD by doing :
   # newfs /dev/rrz6a
   # newfs /dev/rrz6b
   # newfs /dev/rrz6g
   
And in /etc/fstab :   
   /dev/rz6a 		/disk2b
   /dev/rz6b 		swap2
   /dev/rz6g		/disk2a
But I really would like to have one large file system on this 
second disk as opposed to splitting the usable section between
/dev/rz6a and /dev/rz6c. Is it possible to just split this new
disk into one small 300 MB swap partition and assign the rest 
to one partition ?
Sorry - I'm making this more complicated than it really is perhaps.
Thank you,
chas
