How to reset an I/O processor card while the system is up and running
Resetting an IOP restarts and reloads that IOP. Use this procedure to recover from
an intermittent error condition.
Note: You can also perform an IOP reset under the hardware service manager
function (see “Debug the resource” on page 66).
1. Note: You cannot reset the workstation IOP for the workstation at which
you are working or a workstation that is the only one on the system.
Do you want to reset the local workstation IOP?
No Yes
↓ Vary off the local workstation IOP (see “Varying configuration descriptions
on and off”).
Then, go to step 5 of this procedure.
1. Do you want to reset the communications IOP?
No Yes
↓ Vary off all the lines on a communications IOP (see “Varying
configuration descriptions on and off”).
Then, go to step 5 of this procedure.
2. Do you want to reset the cryptographic IOP?
No Yes
↓ You must end cryptographic services. Enter ENDCS (End Cryptographic
Services) command.
To reset the cryptographic IOP, enter STRCS Press F4 to prompt
parameters. Then, enter RESET *YES. This ends the procedure.
3. Do you want to reset a tape, optical, or disk IOP without an attached disk unit?
Yes No
↓ This ends the procedure.
4. Vary off all the IOPs and device descriptions on the IOP (see “Varying
configuration descriptions on and off”).
5. Enter the VRYCFG (Vary Configuration) command. Then, press F4 for prompting.
6. Enter STATUS *ON RESET *YES Then, press the Enter key.
This ends the procedure.
Varying configuration descriptions on and off
The Go Hardware display allows you to access all lines, devices, and IOPs and to
see and change (vary on or off) the configuration status for these resources. The
status of all configuration descriptions can also be displayed or changed (varied on
or off) using the WRKCFGSTS (*NWI | *CTL | *LIN | *NWS | *DEV) command. This
command is also used for varying off a line and all the IOPs and devices under it.
Notes:
1. All active jobs must be ended before you can vary off. You might be able to
enter the WRKACTJOB (Work with Active Jobs) command on the command
line on the WRKCFGSTS display or use the Work with Job option to end active
jobs.
