omdiag: Using the Diagnostic Service 39
– Tape Drive Insert Test — Verifies the tape drive's ability to load a tape cartridge. This test is not
available for autoloader/changer tape drives. This test also writes a small amount of data, verifies
the data written, and then ejects the media.
NOTE: When the media is ejected from the tape drive, run the Tape Drive Insert Test as an individual test. Do
not group this test with any other tests on this device.
– Tape Drive Eject Test — Verifies the tape drive's ability to eject a tape cartridge. It will issue a
Prevent Allow Medium Removal SCSI command and then attempt to unload the tape cartridge.
This test is not available for autoloader/changer tape drives.
NOTE: When the media is ejected from the tape drive, run the Tape Drive Eject Test as an individual test. Do
not group this test with any other tests on this device.
– Check Tape Drive Firmware (optional) — Checks the tape drive firmware revision number to see
if any updates exist.
• SCSI Tape Library/Changer Tests — Performs several tests on a SCSI tape library or changer, which is
connected to a SCSI controller channel using a SCSI cable. Appropriate SCSI controller and tape
changer or library drives must be installed for the tape changer or library to be enumerated. The
following tests are performed on a SCSI tape library or changer:
– Tape Device Self Test — Initially verifies the communication path from the host to the tape drive.
If communication can be established, the test performs a quick test of the drive's RAM and then
performs the built-in RAM diagnostic. This test does not require a tape cartridge. This diagnostic
can vary based on the type of the drive.
– Tape Changer Automation Test — Tests the functionality of the robotic components in the
autoloader or library. The test consists of two individual tests: a slot-to-slot test and a slot-to-drive
test. The complete tape changer automation test repeats both tests twice.
The slot-to-slot test is not supported on all devices. For devices that support this type of
functionality, the test randomly moves tape cartridges from one storage slot to another, and
back again.
The slot-to-drive test randomly loads and unloads tape cartridges to and from one or more drives.
– Check Tape Changer/Library Firmware (optional) — Checks the tape changer/library firmware
revision and verifies if an update is required.
omdiag system
You can use the omdiag system command to test any of the components for the system, regardless of
whether they are part of the chassis. For example, omdiag system memory tests the memory just the
same as if you run omdiag chassis memory.
omdiag system -?
Use the omdiag system -? command to see a list of all components on the system.
