Specifications
SCSICOMP
DESCRIPTION
The Ampro SCSICOMP utility allows you to compare the contents
of
two SCSI direct access
devices (e.g. hard disk drives). Although the program must
be
run
from
~OS,
SCSICOMP
pays
no
attention
to
the
contents
of
the
source
and
destination SCSI devices,
and
does
not
care what
(if
any) operating system
has
been
used to write data to them.
You
can
specify any two SCSI controller IO's, drive Logical
Unit
Numbers
(LUNs),
SCSI
block range to
be
compared.
OPERATION
To
run
the program, type its name at the DOS command line:
A>SCSlCOMP
<
Enter>
The
program
will
display a sign-on message and
will
then
prompt you to press the <
Enter>
key to continue. After you press the <
Enter>
key, the program
will
prompt you for informa-
tion required, including the
fast
SCSI
10,
fast
logical unit number, second SCSI
10,
second
logical
unit
number,
starting block number,
and
number
of
blocks
to
compare.
Then,
the
program
will
compare
the
specified segments
of
the
two SCSI devices
and
report
on
any
errors
or
differences that occur during the comparison.
The
required parameters
are
defmed as follows:
•
SCSI
ID -
Each
device's SCSI
10
is
determined
by
the
jumpecing
of
the
device's
SCSI
controller and
is
in
the range 0 through 7.
• Logical
Unit
Number
(LUN) -
Each
device's logical unit
number
is
based
on
how
the
device
is
connected to the controller and may also depend
on
the setting
of
jumpers
on
the device; it is generally 0
or
1.
• Block
Number
- A SCSI "block" is 512 bytes
of
data;
the
first block
on
the
device is
numberedO.
The
current version
of
SCSICOMP requires that the block starting numbers
on
the two drives
be
the same, so only one starting block number is requested
by
the program.
