IBM Tapeutility, ITDT and mtlib Comands useful for managing Tivoli Storage Manager (TSM) tape library


IBM Tape Diagnostic Tool (ITDT) v7.0 offers multiple functional capabilities that simplify the task of maintaining IBM tape products. The IBM Tape Diagnostic Tool incorporated the original “IBM Tapeutil” and offers a common interface on all platforms for the Tapeutil-interactive and scripting functions. 

The IBM Tape Diagnostic Tool is designed to:

  • Be simply installed and handled.
  • Run quick or extended diagnostics on tape drives to check if the tape device is defective and output a pass/fail result.
  • Invoke tape library self-test operations.
  • Retrieve dumps from tape drives and libraries.
  • Perform firmware update check and retrieval for tape drives and libraries.
  • Perform a firmware update on tape drives or libraries.
  • Test the performance of the environment by completely writing a cartridge and measuring performance.

  • Verify tape drive compression.
  • Measure system performance per system test.
  • Retrieve and display cartridge usage and health information.
  • Verify the encryption environment.
  • Scan the system to discover all supported tape and library devices and show the results in an overview.
  • Perform a connection test.
  • Perform a full write function
  • Migration/Duplication of IBM Tape Drive Cartridge content using physical copy operations including LTFS awareness.
  • Visualize IBM Tape Drive and IBM Tape Library dump and log files.
  • Perform task automation using the ITDT scripting interface.
  • Configure drive parameters as for example TCP/IP settings.
  • Work without tape device driver.
Steps to download the IBM Tape Diagnostic Tool (ITDT):

mtlib Commands

Use the mtlib command as shown below to verify the status of the Enterprise Tape Library 3494. For the purpose of these sample commands, the logical name of the Enterprise Tape Library 3494 is assumed as 3494a.

This command has the following format:

mtlib -l 3494a [-qL | -qI | -qI -v | -DE]
-qL
(Optional) Queries the Enterprise Tape Library 3494 and provides information on the library.
-qI
(Optional) Queries the Enterprise Tape Library 3494 and provides information on the tape volumes in the Enterprise Tape Library 3494. 

-qI -v
(Optional) Queries the Enterprise Tape Library 3494 and provides verbose information on the tape volumes in the Enterprise Tape Library 3494. The verbose information includes the state of the tape volumes, whether a volume is logical, volume class, and volume type. This command is useful to determine if a tape is mounted.
-DE
Queries the Enterprise Tape Library 3494 and returns device information.
Note: For complete information on using the mtlib command, see the Enterprise Tape Library 3494 documentation. Below table has useful mtlib commands.
