NAME

       th_manage - manage the fault injection test harness

SYNOPSIS

       th_manage name instance command

       th_manage path command

DESCRIPTION

       th_manage  applies  the	action	specified  by command to the instance specified by instance of the driver specified by name (or the driver
       instance specified by path). The driver instance must be running fault injection specifications (errdefs) defined by th_define(1M).

       th_manage supports several commands that operate on the driver instance specified by name and instance (or path). The commands are:

       broadcast       Awaken all th_define processes, causing them to display their current status and exit if the errdef is  now  defunct  (that
		       is, if count, failcount , and acc_chk  are all zero).

       clear_acc_chk   Awaken  all th_define processes. If count and failcount are already zero, then set acc_chk to zero, so that th_define exits
		       once it has displayed its status.

       clear_errdefs   Awaken all th_define processes. count, failcount and acc_chk are all set to zero so that all th_define commands	exit  once
		       they have displayed their status.

       clear_errors    Awaken  all  th_define processes. If count is already zero, set failcount and acc_chk to zero, so that th_define exits once
		       it has displayed its status.

       get_handles     List all the access handles.

       start	       Begin or resume execution of all errdefs.

       stop	       Suspend all errdefs for this name and instance (or path).

EXAMPLES

       Example 1: Useful Commands

       To begin the tests, enter:

       # th_manage foo 0 start

       To check the status of the errdefs, enter:

       # th_manage foo 0 broadcast

       This causes each th_define process to print out its current status.

       If the driver has reported a fatal error, you can take the driver offline using libdevice, clear the error condition by entering:

       # th_manage foo 0 clear_acc_chk

       or

       # th_manage foo 0 clear_errors

       and bring the driver online again using libdevice.

       To terminate testing, enter:

       # th_manage foo 0 clear_errdefs
