IBM Tape Diagnostic Tool Both versions provide the user with a single diagnostic program for tapeutil applications. Both SE and GE contain tapeutil functionality with SE also providing scripting capability. Note: The term tapeutil is a synonym for the tool that is delivered with the device driver. For example, this tool is named tapeutil on Unix operating systems; it is named ntutil on Microsoft Windows operating systems. The available advanced operations provided by the IBM Tape Diagnostic Tool can be performed on Tape Drives and Tape Libraries. By using this functionality, the customer can perform maintenance tasks and run diagnostic tasks to determine tape drive issues. This significantly reduces product downtime and increases productivity. The IBM Tape Diagnostic Tool is designed to: v Run quick or extended diagnostics on tape drives v Invoke tape library self-test operations v Retrieve dumps from tape drives and libraries v Perform a firmware update on tape drives or libraries v Test the performance of the environment by completely writing a cartridge and measuring performance v Verify tape drive compression v Measure system performance v Retrieve and display cartridge usage information v Verify the encryption environment This test is used to verify if data on the cartridge was actually written encrypted. v Scan the system to discover all supported tape and library devices. v Perform a connection test This test is used to verify that all devices are attached properly v Perform a sequence of sub-tests to check if the tape device is defective and output a pass/fail result Note: When this test is performed, all data on the cartridge is overwritten. v Perform a full write function This function writes the entire cartridge, overwriting all previous data with a selectable block size containing either compressible or incompressible data and then outputs performance data. Note: When this test is performed, all data on the cartridge is overwritten. v Perform a system test Write different block sizes with compressible and incompressible data and then outputs performance data. Note: When this test is performed, all data on the cartridge is overwritten. v Perform a tape usage function to retrieve statistical data and error counters v Perform a manual inspect function for devices not recognized. The ITDT-SE provides the most important functions of the previous tapeutil tools. As an extension of the current tapeutil variants, the set of operations and functions Chapter 10.
