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 will be run to exercise the drive and media. 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. 11.3 Drives with internal self test features Dell PowerVault 110T LTO-2 drives running the latest version of firmware and Dell PowerVault 110T LTO-3 drives have the ability to do internal device self tests that do not require any other software or host attachment.
