Diagnostics

If Clean, Read, or Write errors are reported by backup software try alternate pieces of media before replacing tape

drives.

To troubleshoot errors with tape drives, you need to determine the root of the problem. Tape related problems

can come from two primary sources; Media and Hardware. Dell Online PowerEdge Diagnostics can be used

under either Microsoft® Windows® or Linux to narrow down the likely cause. This tool can be downloaded for

free from support.dell.com.

Within the Diagnostic tools there is a Media test which can be run in a long test or quick test mode to help with

the diagnosis. The quick test will fill 20 percent of the tape and the long test will write to 80 percent. Reading,

writing, spacing, and verifying will all happen during this test so do not use it as a performance tool.

Note: The Media test will overwrite data on the tape. Dell suggests using a blank (new) or scratch piece of

media.

In the event of a failure complete the following procedure.

1. Run the test on one tape. (We suggest running the full test if you think the errors occur later in the

backup – run the short test if errors tend to occur early in the backup)

2. If a failure occurs, mark the tape and set it aside.

3. Insert another tape and rerun the same test.

4. If failure occurs, clean the drive and try a 3rd tape.

5. If failures persist, contact Dell Support.

Dell Online PowerEdge Diagnostics can be used to troubleshoot tape drives in Linux and Windows.

Note: At the time this document is being written, a tape device driver must be loaded in Windows device

manager in order to run Dell PowerEdge Diags Version 2.2. Future version may eliminate this

requirement.
