c. If the device is not varied off, select Vary off before continuing.
d. Select Vary on for the failing tape unit.
e. Enter
RESET(*YES)
(the Reset command) on the command line.
f. Press Enter.
This ends the procedure.
10. Perform the following:
a. Enter
WRKCFGSTS *DEV *TAP ASTLVL(*INTERMED)
(the Work with Configuration Status command) on the command line.
b. Select Vary off for the failing tape unit and associated devices (the devices you identified in step
7 (See page 231)), and then press Enter.
Note: You must complete the remaining parts of this step before you press Enter again.
c. Select Vary on for the failing tape unit.
d. Enter
RESET(*YES)
(the Reset command) on the command line.
e. Press Enter.
f. Select Vary on for the associated devices (tape units) you identified in step 7 (See page 231). It is
not necessary to use the Reset option again.
Does a system message indicate that the vary on operation failed?
v Yes: Continue with the next step.
v No: This ends the procedure.
11. The Reset is not available, or you were not able to find the Configuration Description name when
using
WRKHDWRSC *STG
(the Work with Hardware Resources command).
You can perform an I/O processor (IOP) reset by performing an IPL of the I/O processor. All devices
that are attached to the IOP will reset.
The following steps describe how to load an IOP, how to configure a tape drive, how to vary on tape
devices, and how to make tape devices available.
12. Is the tape device you are working on an 8mm tape drive?
v No: Continue with the next step.
v Yes: Verify the following on the 8mm tape drive:
– The power and external signal cables are connected correctly.
– The Power switch is set to the On position (pushed in).
Note: The SCSI I/O bus terminating plug for the system-external signal cables is connected
internally in the 8mm tape drive. The 8mm tape drive does not need, and must not have an
external terminating plug.
Is the 8mm tape drive Power light on, and is the Disturbance light off?
– Yes: Continue with the next step.
– No: Go to "TU-PIP2" on page 226 to correct the problem.
This ends the procedure.
13. Is a data cartridge or a tape reel installed in the tape device?
