Media and hardware problem isolation for the 3592 tape drives

Edit online

Refer to steps to determine whether a problem with a 3592 tape drive in the TS4500 tape library is due to faulty media or faulty hardware.

About this task

An error code (FID FE) is generated when the 3592 tape drive experiences an error and cannot determine whether the tape cartridge or the drive hardware causes the problem. The FID FE is not displayed on the drive, but is logged in the sense information that is returned to the host system.

Media and drives can affect each other and the indications can be confusing. You must record the symptoms for the drive and the tape to make problem isolation possible. The failing component or tape must be isolated or the problems are not resolved. Problems can be intermittent, so careful record keeping is necessary. By keeping careful records of transient problems, you enable problem isolation and resolution.

To determine the cause of the read or write errors, use the steps that follow.

Procedure

  1. Ensure that the cartridge maximum usage of 50 cleanings is not exceeded.
    • Ensure that a cleaning cartridge is installed in the tape library.
    • Ensure that the 3592 tape drive is not overdue for cleaning.
  2. Determine which volume serial (VOLSER) numbers or cartridges are potential problems.
    • Note which VOLSERs fail during the operation. (It is possible to have multiple bad cartridges.)
    • Record the Media information Message (MIM) MESSAGE CODE at the host and associated VOLSER numbers, if the host supports MIM messages.
    • If you receive a Service information message (SIM) at the host, get the VOLSER numbers from the message and record those numbers in your TAPE SERIAL LOG.
  3. Determine whether the cartridges are bad.
    • Examine the cartridge for damage. Open the door to observe if the pin is properly seated, and examine the cartridge for cracks. If damaged, repair or replace the cartridge.
      Note: A repaired cartridge can be used long enough to recover data from that cartridge. When the data is recovered, the cartridge must then be taken out of service and discarded, or returned to the plant of origin.
    • If the cartridges appear undamaged and you have access to another 3592 tape drive, try the operation with the suspect cartridges in the other drive. If your cartridges fail in the other drive, replace the media.
  4. Determine whether the drive is bad.
    • Try a new tape on the suspect drive. If it also fails, contact your IBM® Service Representative.
    • If tapes show evidence of damage, do not put any more tapes on the drive until your IBM Service Representative examines the drive.
