Backup software services may interfere with firmware updates, drive detection and diagnostics. It is best to set the backup services to "disabled" then reboot the host and tape drive or library. This will clear any reservation on the library or tape drives.
Installing ITDT-SE (CLI)
ITDT-SE does not have a installer, the installation is simply just extracting files on to the customers machine. The extractor creates a input, license, output and script folders along with the ITDT executable a readme and two other files. No reboot is required.
ITDT-SE (CLI) can be found on www.dell.com. Choose the Powervault tape drive, auto loader or library you are working with. ITDT-SE (CLI) will be found in the Tape Automation Category.
1. Once downloaded right click to run as administrator.
2. Default location is C:\\Dell\Drivers\.....
3 Two files will be extracted.
4. In this instance we are using a Windows host, right click the Windows version, run as administrator.
5. Go into the ITDT folder that is created. To start ITDT, right click the ITDT application and run as administrator.
When first extracted, the output and input folder may not be created. The two folders will be created once the ITDT application is ran.
Tape Drive Log
If a tape drive is failing during backups or while running diagnostics, gathering a drive dump from the tape drive will help determine if the drive needs to be replaced.
If media is suspect, it is beneficial to gather drive dumps from all tape drive in a tape library.
When the drive dump is generated three files will be created in the "output" folder. The files will be "A", "B" and "BLZ". All three files can be useful in determining drive problems.
1. Start the ITDT-SE application by right clicking ITDT found in the ITDT folder.
2. The first time ITDT-SE is ran, the License information will be presented.
3. Press I on the last page to agree.
4. This will bring up the Main Menu page.
5. Press [S] to scan for devices.
6. Select the drive you want to gather the Dump.
7 Press [D] to generate the Dump files.
8. Once complete Dump files will be located in the Output folder where ITDT was extracted.
9. Press [R] to return to device list, select the next tape drive or press [Q] to quit.
10. Dump files generated. Zip all three files for support to review.
Tape Drive Diagnostics
There are several different diagnostics that can be performed using ITDT-SE, run the appropriate diagnostic.
If the tape drive will not start writing to the media, a system test would be useful. The system test is a short diagnostic test.
When trying to determine if that tape drive is having a problem with a read/write head vs media, one of the best ways to help is to run a full write test with a brand new tape.
The full write test will exercise all write heads, and is a longer diagnostic test. Once diagnostics are completed, it will generate a drive dump from the drive, for whichever diagnostic test is run.
Stand Alone tape drive will need a tape inserted into the drive to run tests.
Tape Libraries will need a tape in the I/O station.
Use a blank or scratch tape when running diagnostics as some tests with overwrite the data.
1. Open ITDT-SE (CLI).
2. Select the drive to be tested.
3. Select the diagnostic option.
4. Select [O] for other functions.
5. Full Write test, select [W].
6. Select the block size.
7. Choose what type of data to test. Incompressible data will run at the Native speed of the tape drive.
8. Once diagnostic is complete ITDT-SE will either Pass or Fail.
9. Logs will be generated in the Output folder where ITDT-SE was extracted.
Tape Drive Firmware Update
After updating the firmware on a tape drive, the host will need to be rebooted before running diagnostics or backup jobs.
1. Download the appropriate firmware for the tape drive that is being updated Dell Support Site
2. Extract the firmware, the default location will be C:\Dell\Drivers\.... , note the folder location when files are extracted.
3. Copy the firmware file to the Input folder where ITDT-SE was extracted.
There may be separate firmware files for Full Height and Half Height drives as well as SAS and FC drives.
4. Open ITDT-SE (CLI)
5. Select tape drive to be upgraded.
6. Press [F] for firmware update.
7. Select the firmware file then press [C] to continue.
8. The Directory and Firmware file is listed. Press [S] to start firmware update.
9. Once complete the Status should be Passed.
10. Press [R] to return and select next drive to be update.
11. Once all drives are complete, the server will need to be rebooted before testing or running backup jobs.
Eject Tape Media
The Eject Tape Media function in ITDT-SE may need to be used if a tape will not eject using the backup software. To clear any reservation on the tape drive by the backup software, set all backup services to disable, reboot server and tape device.
Mid-tape recovery could take up to 10 minutes to complete. During the recovery the Single Character Display (SCD) flashes one segment at a time to complete one figure-eight motion, then flashes the number 9, then flashes one segment at a time to complete one figure-eight motion, then flashes the number 8. This continues until the number 1 flashes and the drive completes. You can eject the cartridge once the count down has ended by hitting the eject button.
The normal eject process can take 5 minutes or longer depending on the amount of tape spooled into the drive. The activity LED on the tape drive will stop flashing once activity has stopped.
1. Open ITDT-SE.
2. Select drive that has media loaded.
3. Select [J] to eject media.
4. Result will be Passed if the tape ejected.
The Tape Usage function retrieves statistical data and error counters from a cartridge.
Tape Usage does not create a log file.
1. Open ITDT-SE.
2. Select drive that has media loaded.
3. Select [O] for other options.
4. Select [U] for Tape Usage.
