Chapter 5 SCSI Drive Installation 57
Command Line Options
The SCSIDISK.SYS device driver has several embedded functions
which can be accessed via switches on the command line. These
options are described below, and use the following conventions:
[] items in brackets are optional
* items in brackets followed by an * means repeat 0 or more
times
| choose one of the given items
Please be aware that using spaces in specifying a command line
option is not allowed.
Using the /ASK Option
This option prompts the user at system boot-up whether to load
SCSIDISK.SYS or not. To use this option, the line in
CONFIG.SYS which loads SCSIDISK.SYS should look like this:
DEVICE=C:<PATH>SCSIDISK.SYS /ASK
Using the /UNITS= Option
SCSIDISK.SYS allows the use of removable media, such as
cartridge hard drives, each of which might have a different number
of partitions. If media with different numbers of partitions are
used, this option should be set to the maximum number of parti-
tions on any one media. To use this option, the line in
CONFIG.SYS that loads SCSIDISK.SYS should look like this:
DEVICE=C:<PATH>SCSIDISK.SYS /
UNITS=path:id:lun:num_units
[,path:id:lun:num units]*
For example, if there is a removable media drive at the first host
adapter set to id 2, and three partitions must be reserved, the
command line should be:
DEVICE=C:<PATH>SCSIDISK.SYS /UNITS=0:2:0:3
Remember, no spaces are allowed in specifying a command line
option for SCSIDISK.SYS.
