How to add a 3rd party scsi to an AT&T 3b2

[Geoff Coleman]

	So how do you add a third party scsi device to an
AT&T 3B2 ???

1.) turn off 3b2 and attcah device to scsi bus using an unused
    id #.

2) turn on 3b2 and watch the console (or put a hardcopy device on it)
   The 3b2 will say unknown device maker, model. You need this information 
   in step three.

3) - cd to /etc/scsi
   - run ./edittbl -l to list devices presently known
   - run ./edittbl -i to add a device and answer the questions
	- The first entry is the make and must be padded out to 8 characters
        - The second entry is the model and must be padded out to 16 
          characters.
	- The number of lu's is 1 unless it is a bridge controller.
	- the AT&T device type is ST01 for a tape, SD01 for a disk. 

4) - cd to /usr/lib/scsi
   - using vi (or yout favorite editor) edit tc.index
   - add an entry for your new disk ala the entries already there
        - make sure you have the model number starting at column 9 ( no spaces)
	  and that it occupies 16 spaces ( any less and the format step will
	  fail)

5) reboot the system
	- it should say that you have an unformatted disk at scsi slot n.
	- run format to format the disk (if you get a cannot open scipt file
	  check the spacing of the maker/model lin in tc.index


Hope this helps someone.
