IBM iSeries 820 Hardware Problem Analysis And Isolation

v Yes: Repeat this step while using a new cleaning cartridge. If you are using a new cleaning
cartridge and the Disturbance light does not go off, the possible failing part is the 8mm tape drive.
Go to “TU-PIP3” on page 228.
This ends the procedure.
4.
Is the Disturbance light blinking?
v No: Continue with the next step.
v Yes: Choose from the following:
– If the 8mm tape drive is a type 6390, the possible failing part is the 6390 tape drive.
– If the 8mm tape drive is a type 7208, the possible failing parts are:
a. 7208 tape drive
b. Power supply
c. AMD
Go to “TU-PIP3” on page 228.
This ends the procedure.
5.
Perform the read self-test:
Notes:
a. The 8mm tape drive read self-test and hardware self-test can take up to 5 minutes to run.
b. The tape drive runs the read self-test first. During the read self-test, the Read-Write light blinks,
and the Disturbance and Ready lights are off.
To start the read self-test and hardware self-test, insert the diagnostic cartridge (part 46G2660) into the
tape drive. The following conditions indicate that the read self-test ended successfully:
v The Read-Write light stops blinking.
v The diagnostic cartridge ejects automatically.
v The three status lights go on to indicate the start of the hardware test.
Does the read self-test end successfully?
v No: Does the tape drive eject the diagnostic cartridge?
– Yes: Continue with the next step.
– No: The tape drive is the failing part.
Go to Tape cartridge - Manual removal. After removing the diagnostic cartridge, exchange the
tape drive (see Removable media in Remove and replace procedures).
This ends the procedure.
v
Yes: Go to step 8 (See page 228).
6. Is the Disturbance light blinking approximately four times per second?
v No: Continue with the next step.
v Yes: The possible failing part is the diagnostic cartridge (part 46G2660).
– If this is your first time through this step, get a new diagnostic cartridge. Go to step 3 (See page
226) of this procedure to clean the tape drive again. Afterwards, run the read self-test and
hardware self-test while using the new diagnostic cartridge.
– If this is your second time through this step, the possible failing part is the 8mm tape drive. Go to
“TU-PIP3” on page 228.
This
ends the procedure.
7.
The Disturbance light is blinking approximately once per second.
v If the 8mm tape drive is a type 6390, the possible failing part is the 6390 tape drive.
v If the 8mm tape drive is a type 7208, the possible failing parts are:
a. 7208 tape drive
b. Power supply
c. AMD
