5 Diagnostics 5.1 Troubleshooting Cleaning/Read/Write errors If Clean, Read, or Write errors are reported by backup software try alternate pieces of media before replacing tape drives. If there are invalid media errors reported by the drive via the LED/LCD then also try using an alternate piece of media before replacing the drive. 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. If the intent is to test a specific piece of media then make sure the data contained on that media is backedup elsewhere. If a failure is seen it is important to run the test on more than one piece of media to narrow the issue down to the drive or the tape 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. 5.2 Dell PowerEdge Diagnostics Figure 14 - Dell Online PowerEdge Diagnostic Dell Online PowerEdge Diagnostics can be used to troubleshoot tape drives in Linux and Windows.

Troubleshooting Cleaning/Read/Write errors
If Clean, Read, or Write errors are reported by backup software try alternate pieces of media before replacing tape
drives.
If there are invalid media errors reported by the drive via the LED/LCD then also try using an alternate
piece of media before replacing the drive.
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

.
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.
If the intent is to test a specific piece of media then make sure the data contained on that media is backed-
up elsewhere.
If a failure is seen it is important to run the test on more than one piece of media to narrow the
issue down to the drive or the tape 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.
