OS Level: AIX Versions 3.2.5, 4.1.5, 4.2.1, and 4.3.0

One or more of the following solutions may eliminate the preceding errors:
  1. Replace the tape.
  2. Clean the tape drive.
  3. If solutions 1 and 2 fail, the errors may indicate there is a hardware problem related to the tape drive itself. You should pursue service with hardware support.
  4. If the return code of 48 is occurring on a 20GB tape drive, be aware of the following information:

    NOTE: If you read from anything but a 170 meter tape, you must reset the drive with the reset button on the case and clean the drive. These steps must be completed in order to accomplish any task with a 170 meter tape. This problem is corrected by microcode level 38ZA.
