Thanks for your help,
Problem Statement: I am planning to do a new install of DU 4.0 from
OSF/1 3.0 but would like to do the install on an
external UNISON 4 GB drive which is a Seagate
ST15150N. The drive is hooked up but I believe
I need a disktab entry to install the correct drive
attributes before I do a disklabel and newfs and
set the proper partition sizes. Any advice will be
helpful, both for the UNISON drive and the install
of DU 4.0 on an external disk.
The responses are summarized below:
From: Alan_at_nabeth.cxo.dec.com
If the drive is well behaved, disklabel can get the geometry
and default partition table from the driver. The SCSI-2
standard includes some specific mode pages that a disk can
use to provide geometry information. There is an I/O control
and driver support that will get the information from the
drive when present.

To add a new disk, perform the following commands assuming SCSI
bus 0, SCSI ID 3, and ufs file system:
# cd /dev
# ./MAKEDEV rz3
# cd /sys/conf
# grep rz3 <HOSTNAME>
# grep rz3 GENERIC (if rz3 is NOT in <HOSTNAME>)
# vi <HOSTNAME> (if rz3 is NOT in <HOSTNAME>) (add rz3
after rz0)
# cp /vmunix /vmunix.sav (if rz3 is NOT in <HOSTNAME>)
# doconfig (if rz3 is NOT in <HOSTNAME>) (don't
forget CDFS)
# cp /sys/<HOSTNAME>/vmunix /vmunix (if rz3 is NOT in <HOSTNAME>)
# shutdown -r now (if rz3 is NOT in <HOSTNAME>)
# cd /
# disklabel -z rz3
# disklabel -rw rz3 <disk_type> (if <disk_type> is in /etc/disktab)
# disklabel -rw rz3 unknown (if <disk_type> is NOT in
/etc/disktab)
# disklabel -r rz3
# disklabel -re rz3 (if you want to edit the partitions)
# disklabel -r rz3 (if you edited the partitions)
# newfs /dev/rrz3a (as appropriate)
# newfs /dev/rrz3g (as appropriate)
# newfs /dev/rrz3h (as appropriate)
# mkdir /<dir> (make mount points as appropriate)
# vi /etc/fstab (add mounts as appropriate)
# mount /<dir> (as appropriate)
Thanks very much Alan & Tom for your excellent advice and help.
Have a very Merry Christmas and a Happy New Year!
