IBM Tape Diagnostic Tool Table 30. Definitions of Abort Codes (continued) ABORT CODE ROOT CAUSE END OF DATA End of data encountered before the given amount of data could be read READ FAILED ENCRYPTION ERROR INVALID PARAMETER User entered data length of 0kB If you want to use other ITDT-SE functions, type R followed by the Enter key to return to the device list; otherwise, type Q followed by the Enter key to exit the program. Full Write The Full Write [F] function writes the entire cartridge with a given block size either with compressible or incompressible data and output performance data. Attention: The Full Write function erases data on the cartridge that is used for the test. Notes: 1. The Full Write function takes approximately 2 hours when writing incompressible data, less time for compressible data. 2. The Full Write function runs only on tape drives, not on autoloaders or libraries. The Full Write test can be used to: v Demonstrate that the drive is capable of writing the full amount of data on a cartridge. v Identify system issues with compression. Drive data compression is always switched on during the full write. When run with compressible data, the output shows the compression rate. If the compression rate is higher than 1.0 but the system does not appear to be able to compress data on the cartridge, then check the device driver and software settings to see if they disable compression. 1. After starting ITDT-SE, type S followed by the Enter key to activate the device scan. 2. Select the device you want to write to by entering its number and press the Enter key. Type W and press the Enter key to start the full write. ITDT-SE then switches to the Full Write screen. If no cartridge is inserted, ITDT-SE prompts to insert a cartridge. Either insert a cartridge and press the Enter key or stop the test by typing C followed by the Enter key. Note: If ITDT-SE detects data on the cartridge, it shows the Full Write screen, and displays the following message: Cartridge not empty! Overwrite data? Type Y followed by the Enter key to continue the test if you are absolutely sure that data on the cartridge can be overwritten. If you are unsure, type N followed by the Enter key to stop the test.
