Installation Instructions: AM-650 1/4" Streaming Tape Drive Page 15

PDI-00650-00, Rev. A00

If you have two streaming tape drives, enter both device names after the slash, separated by a comma,

like this:

DEVTBL /STR0,STR1

The device driver program needs to be in system memory, so add the following line somewhere before

the final SYSTEM command:

SYSTEM STR.DVR[1,6]

Since the MTUxxx programs spawn a separate job to communicate with the tape drive, you may need to

increase the number of jobs allocated by the system at boot time. To increase the number of jobs, find

the line which reads:

JOBS nnn

This line is normally one of the first commands in the .INI file. Increase the number of jobs by one.

Testing the Initialization File

When you have finished editing the TEST.INI file, save it and exit. Then, make sure everyone is off

your system, log into OPR:, and use MONTST to test the TEST.INI file. For example:

LOG OPR:

RETURN

MONTST TEST.INI[1,4]

RETURN

When your computer executes the statement

DEVTBL /STR0

in your system initialization command

file, it displays what tape drive was detected and its address. For example:

AM-650 streamer found at SCSI ID: 3

If the computer boots successfully, enter DEVTBL to see a display of the devices on your system; the

SCSI streamer drive should be listed as STR0.

If you have two streaming tape drives, both should appear during initialization and on the

DEVTBL display.

If the computer doesn't boot successfully, or if the streamer does not appear on the DEVTBL display,

press the RESET button to reboot the computer under its original initialization file. Review the changes

you made to TEST.INI, and verify the AM-650 is cabled correctly and its address jumpers are properly

set.

Initial System Testing

Since you had to open the computer to install the AM-650, you may want to run the system self

test to be sure your computer system is operating correctly. Refer to the

Self-Test User’s Manual

for complete instructions on using the self test. Self test does not test the streaming tape drives.

Use MTUSAV to copy a few files onto a blank streaming tape cartridge, then use MTURES to restore

them into a different disk account or onto another logical disk. Use the MTUDIR command to list the

1 2 ... 13 14 15 16 17 18 19 20 21 22 23
