Performing an EDLM Drive Test

If an EDLM drive reports a suspicious number of errors within a given time period, it will be taken offline and not used for testing until brought back online manually. This operation allows testing the drive with a known-good tape cartridge to determine whether the problems detected by the drive are legitimate, or possibly due to a problem with the drive itself. If this occurs, the library will issue a RAS ticket directing you to test the tape drive.

To test the drive:

1. Select Tools > Drive Operations.
   
   The Tools - Drive Operations screen opens.
2. Select Perform EDLM Drive Test and click Next.
   
   The EDLM Drive Test screen appears.
3. Place a known good tape cartridge into the top I/E station slot.

   NOTE: A “known good tape cartridge” means one that is fairly new, formatted, fully written, and that has a good cartridge memory (CM).

4. Select the drive to test and click Apply.
   
   The tape is tested using the known good tape cartridge. When the test completes, a Success or Failure message appears.
   
   

   NOTE: If an EDLM scan is in progress during an intentional or unintentional power cycle, the scan session may remain in "In Progress" status. Verify scan results by looking at the details for the media in question.

5. Do one of the following:
   • If the result is Success — Manually bring the tape drive back online (Tools > Drives > Change Mode).
   • If the result is Failure — If you used a known good tape, a failure generally means the drive has failed. View the RAS ticket details or contact Quantum Support for further analysis.
