Expected results: - If passthrough support is enabled, it should open the device, but not do anything with it. Actual results: I get the following error message from the program when running it against = my fake mpt(4) controller in my VMware fusion instance: # ls -l /dev/pass* crw------- 1 root operator 0x36 Mar 6 20:03 /dev/pass0 crw------- 1 root operator 0x37 Mar 6 20:03 /dev/pass1 # ./cam_open_device da0 cam_open_device: cam_open_device failed: Operation not permitted cam_open_device: cam_errbuf is: cam_real_open_device: couldn't open passthr= ough device /dev/pass0 cam_real_open_device: Operation not permitted # --=20 You are receiving this mail because: You are the assignee for the bug.=
