A Add drive / edit configuration

This option allows a new winchester drive to be added to the SCSI

system, or allows details about an existing drive to be changed.

Information required by SCSIFORM is as follows:

Drive Number

SCSI drive number of the drive you wish to add or edit the

configuration of (4 to 7). Note that drives must be added in ascending

order, with drive 4 first.

SCSI Id No.

The SCSI Id number of the device you wish to add (usually `0' for Oak

Drives).

LUN

SCSI logical unit number of the unit you wish to add (usually 0 for

winchesters, but may be 1 for a second drive on an 'Adaptec' type

controller card).

WPROT

Whether or not you wish the drive to be write protected (Y write

protected / N unprotected).

WPROT Lock

Whether or not you want the write protect status to be alterable via the

*WPROT command (Y locked / N alterable via *WPROT)

STOP UNIT

Whether or not to issue a SCSI Stop Unit command to the drive when

dismounting. With Oak Winchesters you should answer N to this

question. The SCSI Stop Unit command parks the heads of the

winchester, and also, on some drives, stops the spindle motor. This can

be a problem, as the next time the drive is accessed, it will return a not

ready error. Only answer Y to this question if the drive you are adding

does not have auto-parking heads and does not shut down completely

on receipt of the Stop Unit command (test this last feature by

experiment - if the drive subsequently returns a `not ready' error, don't

issue the Stop Unit command).
