Description

The shconf command is used to display or specify the parameters of the priority problem detection and lost I/O detection.

For the priority problem, the user can specify five actions described below and for each action, the user can specify the priority level to check, the time out while no process or thread executes at a lower or equal priority, the terminal device for the warning action, and the getty action:

pp_cmd	Launches a command specified by the path parameter.
pp_errlog	Logs an error in error log.
pp_login	Launches a getty at the highest priority on the serial line specified by the terminal device parameter (term).
pp_reboot	Reboots the system.
pp_warning	Displays a warning message on the console specified by the terminal device parameter (term).

For lost I/O, the user can specify the actions listed below and errlog, which is automatic when lost I/O detection is enabled. There is a unique timeout which applies to all enabled actions.

lio_warning	Displays a warning message on the console specified by the terminal device parameter (term).
lio_reboot	Creates a system dump and reboots the system

Flags

-d	Displays if priority problem detection and lost I/O detection are enabled or not.
-R	Restore the default values for a specified name of detection.
-a Attribute=Value	Specifies the attribute value pairs used for changing specific attribute values.
-D	Displays the default values for a specified name of detection.
-E	Displays the effective values for a specified name of detection.
-H	Displays the headers above the column output. When used together, the -O flag overrides the -H flag.
-l Name	Specifies the detection name.
-O	Displays all attribute names separated by colons and, on the second line, displays all the corresponding attribute values separated by colons. The attribute values are current values when the -E flag is also specified and default values when the -D flag is specified. This flag cannot be used with the -a flag.
