This program is

important

for several

applications.

You will probably

nced

this program

if

you

use

removable

media disk

drivcs

(snch

ss the

Ricoh,

Bernoulli or

Syfotcst

cortridgc

sytcms), and wish

thc computer

to

recognize

r caftridge

you

insert aftcr

the

computer

is

running.

You will

also need this

program

if

you

arc

using

SCSI

deviccs

(such

os

Wangtek tape d.ritcs)

that

require their

"disconnect"

fl"g to

be tumed

off.

Such dcvices

cannot

have this

flag

set by

FaaastPrep.

There

arc four

options

for using

GVPScsiCtrl

from the

CLL There

is

one

option

for

using

this

program

from

thc

WorkBench.

Wotkbendt:

When

the

GVPScsiCtrl

icon is

double

clicked using

the

Workbcnch

interFrcc,

a

command is scnt

ro the

GVP

scsl controller

that causes

it

to search

for

any

changed volumes (sach

os SyQucst

cartrid.ges) to

mount.

This

functions

essentially

the

same as

using the

-rn

CLI

option

described

below.

Thic form of tlrc

command differs from thc abovc in

that it is

ablc

to

recognizc hard

drivcs or

othcr

devices

that

were

not

prescnt at

startup.

An

examplc mlght

trkes an

In such a

case,

thc

would

not

recognize

any

drivcr that had not

The + option, by

contrast, forceo

thc SCSI

(an

it

will skip

to thc

GVPScdCtd

-s

This

form

of

thc

commrnd

functions

similar to the

-m

option

describcd abovc.

It differs

&om

thc

prcviour

form in

that

lt

will

wait

runtil nll deviccs return

succescfully

should

find an

cmpty SyQucst drive, br

thc
