.SH NAME
th_manage \- manage the fault injection test harness
.SH SYNOPSIS

\fBth_manage\fR \fIname\fR \fIinstance\fR \fIcommand\fR
.fi

\fBth_manage\fR \fIpath\fR \fIcommand\fR

.SH DESCRIPTION
.sp
.LP
\fBth_manage\fR applies the action specified by \fIcommand\fR to the instance
specified by \fIinstance\fR of the driver specified by \fIname\fR (or the
driver instance specified by \fIpath\fR). The driver instance must be running
fault injection specifications (errdefs) defined by \fBth_define\fR(1M).
.sp
.LP
\fBth_manage\fR supports several commands that operate on the driver instance
specified by \fIname\fR and \fIinstance\fR (or \fIpath\fR). The commands are:
.sp
.ne 2
.mk
.na
\fB\fBbroadcast\fR \fR
.ad
.RS 18n
.rt  
Awaken all \fBth_define\fR processes, causing them to display their current
status and exit if the errdef is now defunct (that is, if \fIcount\fR,
\fIfailcount \fR, and \fIacc_chk \fR are all zero).
.RE

.sp
.ne 2
.mk
.na
\fB\fBclear_acc_chk\fR \fR
.ad
.RS 18n
.rt  
Awaken all \fBth_define\fR processes. If \fIcount\fR and \fIfailcount\fR are
already zero, then set \fIacc_chk\fR to zero, so that \fBth_define\fR exits
once it has displayed its status.
.RE

.sp
.ne 2
.mk
.na
\fB\fBclear_errdefs\fR \fR
.ad
.RS 18n
.rt  
Awaken all \fBth_define\fR \fBprocesses\fR. \fIcount\fR, \fIfailcount\fR and
\fIacc_chk\fR are all set to zero so that all \fBth_define\fR commands exit
once they have displayed their status.

Awaken all \fBth_define\fR processes. If \fIcount\fR is already zero, set
\fIfailcount\fR and \fIacc_chk\fR to zero, so that \fBth_define\fR exits once
it has displayed its status.

\fBExample 1 \fRUseful Commands
.sp
.LP
To begin the tests, enter:

.sp
.LP
\fB#\fR \fBth_manage\fR \fBfoo\fR \fB0\fR \fBstart\fR

.sp
.LP
To check the status of the errdefs, enter:

.sp
.LP
\fB#\fR \fBth_manage\fR \fBfoo\fR \fB0\fR \fBbroadcast\fR

.sp
.LP
This causes each \fBth_define\fR process to print out its current status.

.sp
.LP
If the driver has reported a fatal error, you can take the driver offline using
\fBlibdevice\fR, clear the error condition by entering:

.sp
.LP
\fB#\fR \fBth_manage\fR \fBfoo\fR \fB0\fR \fBclear_acc_chk\fR

.sp
.LP
or

.sp
.LP
\fB#\fR \fBth_manage\fR \fBfoo\fR \fB0\fR \fBclear_errors\fR

.sp
.LP
and bring the driver online again using \fBlibdevice\fR.

.sp
.LP
To terminate testing, enter:

.sp
.LP
\fB#\fR \fBth_manage\fR \fBfoo\fR \fB0\fR \fBclear_errdefs\fR
