A tape or a 3590 Tape Unit failure occurred.
Note: For tape device and IOP reset procedures, see “TU-PIP4” on page 453.
1. Is the operating system available and can you enter commands from the
command line?
Yes No
↓ Go to step 3 of this procedure.
2. Is OS/400 available on the system (see “Determining the Dominant Operating
System” in the iSeries Service Functions)?
No Yes
↓ Use the on-line problem analysis procedures to isolate the problem.
Use the WRKPRB (Work with Problem) command to determine if a
recent problem was entered in the problem log, or use the VFYTAP
(Verify Tape) command to run verification tests.
3. Verify that the 3590 is powered on.
4. Ensure that the 3590 SCSI address is set to 0.
5. Verify that the 3590 On-line/Off-line switches are set to the On-line position.
6. Load the first tape.
