(_)_/_/ Tape Diagnostic Utility, Version 2.1
Copyright 1998, Seagate Technology, Inc. All rights reserved.
*************************************************************
This package contains a diagnostic utility for testing SCSI and ATAPI
Travan, DAT, and AIT tape drives from Seagate, Conner and Archive.
SGTAPE21.EXE can be used with most Intel-based systems, including
those running DOS, Windows 95/98/NT, Windows 3.x. The package also
contains NWSGTAPE.NLM for NetWare 3.x, 4.x, and 5.x servers.
If backup operations are not functioning correctly, use these
diagnostic utilities to:
* Verify that the system is communicating with the tape drive.
* Confirm that the tape drive can successfully write data to
a tape and read it back accurately.
SGTAPE 2.1 contains the following enhancements over version 2.0a:
* A single program, SGTAPE21.EXE, now works with both SCSI and
ATAPI tape drives.
* The user can specify number of megabytes to be used when
performing a read/write test.
NOTE: Exceeding the capacity of the Tape will result in the
following message: "Unexpected attempt to read beyond the end of
data. Retry the read-only portion of the test and set the number
of megabytes to less than or equal to previously written data or
perform the Read/Write test followed by the read only test."
* SGTAPE now includes a read-only option for the purpose of
testing tape interchange capability.

-------------------------------------------------------------------
1. Copy the SGTAPE files to a bootable diskette.
2. Copy the ASPI DOS device driver for your SCSI card to the
diagnostic diskette.
NOTE: Most DOS ASPI drivers are either in a DOS directory on
your SCSI card installation diskette or have already been
installed on your hard drive. Below are examples of ASPI
driver files from two manufacturers whose cards have been
tested with the diagnostic utility:
Adaptec--aspixdos.sys (where x is 2, 4, 7 or 8)
Bus Logic--btdosm.sys
3. Create a CONFIG.SYS file on the diagnostic diskette:
* Open a new file in DOS Edit or Notepad.
* In this new text file, type DEVICE= followed by the
appropriate path and device driver filename.
Example: DEVICE=X:\ASPI8DOS.SYS (where X is the letter of
your diskette drive).
* Save the file as CONFIG.SYS on the diagnostic diskette and
exit the program.
4. Reboot your system using the diagnostic diskette.
5. At the A: prompt, type SGTAPE21 <ENTER> and follow the on-screen
instructions.
1.1 Advanced Options
--------------------
Before running the diagnostic utility, you can set an environment
variable to control the following operations. More than one variable
can be set if desired.
Usage:
SET SGTAPE21=x where x is one of the following:
b (or B) = initiates a bus reset before test unit ready
e (or E) = logs READ errors
c (or C) = compression enabled (default is compression disabled)
r (or R) = skips retension for minicartridge drives
Example: SET SGTAPE21=EC logs the READ errors with compression
enabled. To clear all options, type SET SGTAPE21= <ENTER>
1.2 Quick Troubleshooting
-------------------------
Tape drive not recognized at boot:
* If you are booting from the diagnostic diskette, check the
CONFIG.SYS file and make sure the DEVICE= line is typed
correctly.
* Make the tape drive is receiving power. Insert a tape in the
drive. If the drive spins the tape, it is receiving power.
* If you have an external tape drive, make sure the power switch
is on and the drive is plugged into an outlet that is working
properly.
* If you have an internal tape drive, make sure the power
connector is secure. Try another power connector if available.
* Verify that the SCSI cable is securely connected to the tape
drive and SCSI card.
SCSI card not recognized at boot:
* Make sure that SCSI card is fully inserted into the expansion
slot.
* Make sure that the SCSI card's jumpers or switches are set
correctly according to the manufacturer's instructions.
* Run the diagnostics that came with the SCSI card to determine
if the card is functioning properly.
NOTE: Tape drives attached to an Adaptec 3940 card will only
be recognized on Channel A.
SGTAPE.EXE causes the computer to hang:
* Check your system, SCSI card, or ASPI device driver
documentation for the appropriate setup options.
* Your SCSI card may not be compatible with SGTAPE 2.1.
2.0 Testing ATAPI drives on DOS, Windows 95/98, NT, and 3.x systems.
--------------------------------------------------------------------
1. Copy the SGTAPE files to a bootable diskette.
2. Boot the system from the diskette.
3. Type X:\SGTAPE21 (where X is the letter of your floppy drive).
4. Follow the on-screen instructions.
2.1 Advanced Options
--------------------
Before running the diagnostic utility, you can set an environment
variable to control the following operations. More than one variable
can be set if desired.
Usage:
SET SGTAPE21=x where x is one of the following:
b (or B) = initiates a bus reset before test unit ready
e (or E) = logs READ errors
c (or C) = compression enabled (default is compression disabled)
r (or R) = skips retension for minicartridge drives
Example: SET SGTAPE21-S=EC logs the READ errors on with compression
enabled. To clear all options, type SET SGTAPE21= <ENTER>
2.2 Quick Troubleshooting
-------------------------
Diagnostic utility does not detect tape drive:
* Make sure the ATAPI data cable is securely connected to the
drive.
* Make sure the power connection is secure. Try another power
connector if available.
3.0 Testing SCSI tape drives using NWSGTAPE.NLM on a Netware Server
-------------------------------------------------------------------
1. Make sure the ASPI device driver for your SCSI card has been
installed on the Netware server and included in startup.ncf.
For additional information, refer to your SCSI card
documentation.
2. Copy NWSGTAPE.NLM from the diagnostic diskette to the location
on the server that contains NLM files.
NOTE: You can also run this utility directly from the diagnostic
diskette.
3. Using the load command, run the diagnostic utility NWSGTAPE.
Example: load X:\NWSGTAPE (where X is the letter of your floppy
drive).
4. Follow the on-screen instructions.
3.1 Important Netware Notes
---------------------------
NWSGTAPE.NLM has been seen to exhibit the following symptoms after
saving the log file when using an Adaptec 2940 SCSI card:
* Time delay before returning to console prompt.
* Server hang if program is run twice.
* Server ABENDS.
To prevent this from occurring, make sure you are loading the
AIC7870.DSK ASPI driver in the STARTUP.NCF file. Do not enter it
manually at the server console.
If running NWSGTAPE.NLM a second time hangs on "Searching for Tape
Drive.",go to the console prompt and enter LIST DEVICES. This sends
a reset to the tape drive, allowing it to be detected by NWSGTAPE.NLM.
If you are receiving tape I/O errors when running program, check
STARTUP.NCF for another application that is using the tape interface,
such as TAPEDAI.DSK. (TAPEDAI.DSK is used for running tape drives with
SBACKUP.)
If you are using the Adaptec 1540 SCSI card and NWSGTAPE shows
"Tape Drive Not Found:" errors, insert the following command in
STARTUP.NCF:
SET AUTO REGISTER MEMORY ABOVE 16 MEGABYTES = OFF
3.2 Advanced Options
--------------------
Before running NWSGTAPE.NLM, you can set an environment variable to
control the following operations:
b (or B) = initiates a bus reset before test unit ready
e (or E) = logs READ errors
c (or C) = compression enabled (default is compression disabled)
r (or R) = skips retension for minicartridge drives
Example: To log READ errors on a with compressionl enabled, type
LOAD NWSGTAPE EC <ENTER>. To clear the previous options,
type SET SGTAPE21= <ENTER>
3.3 Quick Troubleshooting
-------------------------
Tape drive not recognized at boot:
* Make the tape drive is receiving power. Insert a tape in the
drive. If the drive spins the tape, it is receiving power.
* If you have an external tape drive, make sure the power
switch is on and the drive is plugged into an outlet that is
working properly. Check both ends of the power cord to make
sure they are securely connected.
* If you have an internal tape drive, make sure the power
connector is secure. Try another power connector if available.
* Make sure the SCSI cable is securely connected to the tape
drive and SCSI card.
SCSI card not recognized at boot:
* Make sure that the SCSI card is fully inserted into the
expansion slot.
* Make sure that the SCSI card's jumpers or switches are set
correctly.
* Download the latest ASPI driver from your SCSI card
manufacturer's web site.
* Run MODULES to verify that the proper ASPI NLM is being loaded
on server startup. If not, load it manually before running
NWSGTAPE.
* Run the diagnostics that came with the SCSI card to determine
if the card is functioning properly.
NOTE: Tape drives attached to an Adaptec 3940 card will only
be recognized on Channel A.
NWSGTAPE.NLM causes the system to hang:
* Check your system, SCSI card or ASPI device driver
documentation for the appropriate setup options.
* The SCSI card is not compatible with the diagnostic utility.
