tests and follow the on-screen instructions.
• Normal R/W Test — Runs a shortened version of the Performance R/W Test. It
does not include the POST diagnostic, calibrate drive, or unique tape motion
tests. It checks the motors and head by running read/write tests on a
shortened section of tape, both inbound and outbound. Takes approximately 4
minutes (if no error occurs) to 9 minutes (if calibration is required).
• Perform. R/W Test (Performance R/W Test) — Runs most of the tests that
normally occur when the library is powered ON (POST). When prompted,
load a CE scratch cartridge to run the calibrate drive, read/write, and tape
motion tests. These tests calibrate the read/write channel to optimum settings,
run a long read/write test using all servo positions, and exercise all of the tape
motion functions of the drive. Takes up to 30 minutes.
• Media Test — Runs tests on the tape cartridge media. When prompted, insert
the cartridge to test into the I/O Station. This test overwrites any data on the
tape cartridge. It runs read/write tests on the outer tracks of the tape to verify
the media tracking and performance. Takes approximately 9 minutes.
• Head Test — Runs read/write tests on the tape drive head. When prompted,
insert a cartridge into the I/O Station. It runs read/write tests on the inner
tracks of the tape to verify the head performance. Takes approximately 6
minutes.
• Fibre Wrap Test — Runs tests on the fibre channel through the fibre channel
wrap plug.
Note: Fibre Wrap Plugs must be installed in both Fibre Channel ports on the
drive sled in order for the wrap test to run successfully.
