Go to “TU-PIP3.”
This ends the procedure.
8. The tape drive runs the hardware self-test. During the hardware self-test, the three tape drive status
lights are on for 15 to 30 seconds. The three status lights go off when the hardware self-test ends
successfully.
Does the hardware self-test end successfully?
v
Yes : Continue with the next step.
v No : When the hardware self-test does not end successfully, the following conditions occur:
– The three status lights do not go off.
– The Ready and Read-Write lights go off.
– The Disturbance light blinks approximately once per second.
Possible failing parts are:
– 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.”
This ends the procedure.
9. The read self-test and hardware self-test ended successfully.
Was the user’s original tape identified as the probable cause of failure?
v Yes : Perform the following:
a. Mark and date the data cartridge to indicate that it failed with a permanent error.
b. Discard this data cartridge when:
– Volume statistics (if available) indicate a problem with the data cartridge.
– A total of three permanent errors have occurred with the same data cartridge.
c. If possible, continue operations with a new data cartridge.
Go to “TU-PIP3.”
This ends the procedure.
v No : Go to “TU-PIP3.”
This ends the procedure.
TU-PIP3: For use by authorized service providers.
You were directed here because you may need to exchange a failing part. The failing part was determined
from one of the following:
v
Other problem isolation procedures
v
The Failing item column of the tape unit reference code table
v
Tape unit service guide
Read the “Tape unit PIPs” on page 224 before continuing with this procedure.
Note: Occasionally, the system is available but not performing an alternate IPL (type D IPL). In this
instance, any hardware failure of the tape unit I/O processor, or any device attached to it is not critical.
With the exception of the loss of the affected devices, the system remains available.
1. If the system has logical partitions, perform this procedure from the logical partition that reported the
problem. To determine if the system has logical partitions, go to Determine if the system has logical
partitions before continuing with this procedure.
2. Do you need to exchange a possible failing device?
