Drive diagnostics are separated into two categories:
• Drive Tests — Does not require you to use a scratch tape.
•
Media Tests — Requires you to insert a scratch tape in the top I/E station slot to perform the test.
Drive Tests
The Drive Tests currently include only one test, the Drive Reset operation.
Drive Reset
The Drive Reset operation power cycles the tape drive while the tape drive remains in the drive sled in the library. You may
want to perform a reset if a tape drive does not come ready or it is not behaving properly (for example, if a tape is stuck in
the drive and will not unload).
After the reset operation completes, the tape drive is rebooted and reconfigured. This takes about 60 seconds. Wait 60
seconds before performing further drive operations.
Note: This operation should not be performed concurrently by multiple administrators. You can access the screen, but
you cannot apply changes while another administrator is performing the same operation.
The paths to open the appropriate screens are as follows:
• From the Web client, select Tools > Diagnostics, then select Drives > Drive Tests > Drive Reset.
• From the operator panel, select Tools > Drive Mgmt > Reset drives.
Media Tests
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.
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.
