Media Tests 13
The Media Tests are drive tests that require you to insert a scratch or
suspect tape into the library’s top (uppermost) I/E station slot. The
following tests are available:
• Drive Self Test — Performs the drive’s Power On Self Test (POST) to
make sure that drive hardware is working properly.
•
Read/Write Test — Reads and writes 96 wraps worth of data in each of
the scratch tape’s four data sections. During the test, the drive
overwrites the data on the scratch tape.
• Fast Read/Write Test — Reads and writes two wraps worth of data in
each of the scratch tape’s four data sections. During the test, the drive
overwrites the data on the scratch tape.
• Media Test — Run this test if you suspect media damage in a tape
cartridge. Since media damage usually comes from the tape edges,
this test reads and writes two wraps worth of data on each of the two
outside data bands on both edges of the tape for the entire length of
the tape. For this test, insert the suspect cartridge in the top I/E
station slot. The data will be overwritten on the suspect cartridge.
Media tests cannot be performed from the operator panel. The path to
open the appropriate screen is as follows:
• From the Web client, select Tools > Diagnostics > Drives > Media Tests.
Robotics Diagnostics
The Robotics diagnostics currently include only one test, the Get/Put
Test.
Get/Put Test 13
The Get/Put Test requires the robot to remove one tape cartridge from
the top I/E station slot, and then put the tape cartridge back into the same
slot. To run this test, you must insert a tape into the library’s top
(uppermost) I/E station slot.
