6.4.1 Starting the Test
A Standalone Diagnostic test requires a tape that is not
CAUTION: Since the test involves write operations, the existing tape contents will be destroyed!
1.Make sure that no cartridge is loaded.
No cartridge should be loaded at this stage. If a cartridge is loaded it can be ejected by clicking the Eject Button.
2.Enter Service Mode by keeping the Eject Button pressed for at least 6 seconds.
The Ready LED (on the left) starts flashing fast (indicating the drive is in Service Mode and that Service entry number 1 is active).
3.Insert the tape cartridge into the drive within 15 seconds.
The drive loads the cartridge and the Ready LED starts flashing indicating that Standalone Diagnostics has started. The eject button has now returned to normal mode. During the Standalone Diagnostics test, it is possible to abort the test and eject the cartridge by clicking the eject button. The drive indicates the detection of the abort request by flashing both the Ready and Activity LEDs. Depending on at which stage the test is aborted, it may take a while before the drive starts the eject operation. When the cartridge has been ejected, all LEDs are turned off (the Cleaning LED may however be on).
The Ready LED will continue flashing during the complete test. The Activity LED will be flashing when the test performs tape motion.
If no cartridge has been inserted after 15 seconds, the LEDs revert back to their initial state and the Eject Button must be pressed for 6 seconds again to get back to Service Mode.
6.4.2 Test Sequence
The Tandberg LTO HH Standalone Diagnostics test will perform the following operations:
Collect Information. Reads and stores drive and medium information:
•Firmware and Drive ID
•Tape type and format
•Cartridge serial number
•Error History Log and Log page 0x33 from EEPROM
•
Mainboard Test. Tests the mainboard hardware.
Cartridge Manipulation Test. The Cartridge Manipulation Test performs the same mechanical movement operations as those performed during Cartridge Load and Eject.
Read/Write Test. This test involves actual reading and writing on the tape medium. A write pass and a read pass are executed.
When the test has completed without errors the tape cartridge is ejected. No LEDs will be lit (the Cleaning LED may however be on).
6.4.3 Failure Indication
When a failure has been detected the tape is not ejected and the Failure LED will be flashing.
Detailed information can be retrieved by the ‘Receive Diagnostic Results’ SCSI command.
