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.

One must be careful with this. It is true that the fields have the mentioned widths, but some devices seem to treat the Inquiry Response as one 24-byte field instead of the two fields mentioned above: NCR is guilty of this on their tape controller products.
