7 Verifying the Installation

Verifying the Installation of the Drive (UNIX)

As part of the installation process, you will have installed the appropriate device driver for your UNIX system, and created device files to communicate with the tape drive.

This section describes how you can verify that the installation has been performed correctly.

In outline, the procedure is as follows:

1.Check the tape drive responds to a rewind command.

2.Write test data to a tape.

3.Read the test data from the tape.

4.Compare the data read from the tape with the original data on disk.

To verify the installation:

1.Test the SCSI connection to the tape drive by doing a rewind operation:

a.If there is a tape cartridge already in the drive, remove it.

b.Insert a tape cartridge.

c.Rewind the tape using the command line:

% mt -f <device file> rewind

For example, on HP-UX:

% mt -f /dev/rmt/0mnb rewind

If the command completes successfully, there will be no feedback. If it fails, you will see an error message on the console. The hardware installation may be faulty. Check the troubleshooting section of the User’s Guide for help in identifying the problem.

2.Write a sample file to tape, using ‘tar’:

%cd /

%tar cvf <device file> <file>

The options to tar have the following meanings:

cCreate a new archive (backup file) on the device. v Operate in verbose mode.
