Tests included in Dell PowerEdge Diagnostics are the following:

1. The media can be used to determine if errors are related to tape hardware or certain pieces of media.

•

The media test can be run in full mode which will fill 80 percent of the tape.

•

The media test can also be run in quick mode that will fill 20 percent of the tape.

Note: These tests could take between 2 to 5 hours. Read, Write, space, rewind, and verify

2. The Drive Insert test will test the capabilities of the drive to mount, thread, and do a short write

operation to the tape. A tape must be present in the drive to run this test.

3. The Tape Drive Eject test can be used to try to eject a stuck tape. This test will not work under true

hardware failures. If the stuck tape is due to software this test could work when trying to eject a stuck

tape.

4. The Tape Device Self test can be used to do a quick verify of drive operations without spending

hours writing to tape in search of bad media as seen in the Media test. This test will usually finish within

5 minutes.

6. Use the Tape Device Firmware Check test to verify that the drive firmware is up-to-date. New

firmware can fix many types of known issues.

Note: If a tape is stuck in an LTO drive the firmware can not be updated.
