v No: Continue with the next step.
v Yes: Remove the data cartridge or tape reel. Continue with the next step.
14. Can you enter commands on the command line?
v Yes: Continue with the next step.
v No: Perform the following:
a. Power off the system (see Power on/off the system and logical partitions).
b. Power on the system.
The system performs an IPL and resets all devices. If the tape device responds to SCSI address 7,
the system configures the tape device.
This ends the procedure.
15. Verify that automatic configuration is on by entering
DSPSYSVAL QAUTOCFG
(the Display System Value command) on the command line.
Is the Autoconfigure device option set to 1?
v Yes: Continue with the next step.
v No: Perform the following:
a. Press Enter to return to the command line.
b. Set automatic configuration to On by entering
CHGSYSVAL QAUTOCFG '1'
(the Change System Value command) on the command line.
Note: QAUTOCFG resets to its initial value in step 21 (See page 234)
c. Continue with the next step.
16. Perform the following:
a. Enter
STRSST
(the Start SST command) on the command line.
b. On the Start Service Tools Sign On display, type in a User ID with QSRV authority and Password.
c. Select Start a Service Tool—>Hardware Service Manager—>Logical Hardware
Resources—>System Bus Resources. The Logical Hardware Resources on System Bus display
shows all of the IOPs.
d. Find the IOP you want to reset. You must ensure that no one is using any of the tape units,
communication channels, or display stations that are attached to the IOP you want to reset.
Does a "*" indicator appear to the right of the IOP description?
v No: Continue with the next step.
v Yes: Disk units are attached to the IOP.
Perform the following:
a. Press F3 until the Exit System Service Tools display appears.
b. Press Enter.
c. Power off the system (see Power on/off the system and logical partitions).
d. Power on the system.
The system performs an IPL and resets all devices.
This ends the procedure.
17. Perform the following:
a. Select I/O debug—>IPL the I/O processor.
b. When the IOP reset is complete, continue with the next step of this procedure.
