Users can use the new generic argument, -Q task_attr, to specify a task attribute (simple, ordered, head of queue, aca) for the commands issued. The the default is simple, which works with all SCSI devices that support tagged queueing. This will mostly be useful for debugging target behavior in certain situations. You can try it out by compiling CTL with CTL_IO_DELAY turned on (in sys/cam/ctl/ctl_io.h) and then do something like this with one of the CTL LUNs: ctladm delay 0:0 -l done -t 10 camcontrol tur da34 -v And at then before the 10 second timer is up, in another terminal: camcontrol inquiry da34 -Q ordered -v The Inquiry should complete just after the TUR completes. Ordinarily it would complete first because of the delay injection, but because the task attribute is set to ordered in this case, CTL holds it up until the previous command has completed. sbin/camcontrol/camcontrol.c: Add the new generic argument, -Q, which allows the user to specify a SCSI task attribute. The user can specify task attributes by name or numerically. Add a new task_attr arguments to SCSI sub-functions. sbin/camcontrol/attrib.c, sbin/camcontrol/camcontrol.h, sbin/camcontrol/fwdownload.c, sbin/camcontrol/modeedit.c, sbin/camcontrol/persist.c, sbin/camcontrol/timestamp.c, sbin/camcontrol/zone.c: Add the new task_attr argument to SCSI sub-functions. sbin/camcontrol/camcontrol.8: Document the new -Q option, and add an example.
