Intermittent Errors
This procedure defines using a
trace tool. The trace tool is used under direct assistance from your next
level of support.
1. Get the layout of failing SCSI bus. The maximum SCSI bus length for a differential SCSI bus is 25 M
(82.02 ft) minus 0.2 M (0.66 ft) per connection. Figure 280 shows an example of how to calculate the
bus length. Figure 281 shows the cable part numbers for each length.
23.7M = .5M + .2M + .5M + .2M + 4.5M + .2M + 12M + .2M + 4.5M + .2M + .5M + .2M
Figure 280. SCSI Bus Cable Lengths
2. Obtain the errors that the device reported to the host. For example, if the device is attached to a
RS/6000, run tapeutil. Select option 9, Error Log Analysis. Gather all possible error information.
Note: If you run a SCSI bus trace tool and you have more than one drive running, the non-failing drives
may overlay the error.
If Single Drive on SCSI Bus
1. Get a 3570 microcode dump and send it to your next level of support for analysis if the next step fails
to fix the fault.
2. Replace or swap the SCSI bus cable and the terminator.
3. Start the trace of the next failure. For example, if you are using the AIX Tape Device Driver, type atrc
to start the trace.
4. Connect the SCSI bus trace tool if a failure occurs. On the next failure, get a 3570 microcode dump
and a SCSI bus trace. Send the dump and trace to your next level of support for analysis.
