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
