- Put the drive information in /etc/fstab as follows:
-
- I assume that your external drive is SCSI device 0 and your interal is
- SCSI device 1 (default address for internal HD in NeXTStations).
-
- If you use "bsd" to boot, then the NeXT will boot from the first SCSI
- device it finds, which would be the external drive since it has a lower
- id. The first SCSI device is /dev/(r)sd0a. The second is /dev/(r)sd1a.
- The third is /dev/(r)sd2a and so on. The second partion of the second
- device is /dev/(r)sd1b...
-
- If you look in your /etc/fstab you should see something like the following
- (the one below is from my workstation):
-
- #
- # DO NOT DELETE THIS FILE, IT IS REQUIRED FOR BOOTING
- #
- # This file contains information used to mount local hard disks.
- # Consult your system administration and networking manual
- # for information on adding local disks. Information on the format
- # of entries in this file can also be found in the fstab man page,
- # search for fstab in Digital Librarian.
- #
- /dev/sd0a / 4.3 rw,noquota,noauto 0 1
- #/dev/sd1a /CD-Rom 4.3 ro,noquota 1 2
-
-
- The lines beginning with a # are comments are are ignored. The line
- /dev/sd0a tells unix to mount the device /dev/sd0a (first SCSI device
- found) as / which is the root level and that it is a 4.3bsd filesystem,
- with read and write, no quotas and do not automount it.
-
- Add a line like
-
- /dev/sd1a /desired/path 4.3 rw,noquota 1 2
-
- to your /etc/fstab and the internal disk will be mounted at /desired/path.
-
- Btw, the line with
- #/dev/sd1a /CD-Rom 4.3 ro,noquota 1 2
-
- shows how I would mount a NS3.0 CD-Rom for exporting to the cluster (you
- must mount it READONLY!!).
