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).
