may only specify a bus to scan, or a lun. Scanning all luns on a target
isn't supported.
.It reset
Tell the kernel to reset the given bus (XPT_RESET_BUS) by issuing a SCSI bus
reset for that bus, or to reset the given bus:target:lun
(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
connecting to that device. Note that this can have a destructive impact
on the system.
.It defects
Send the SCSI READ DEFECT DATA (10) command (0x37) to the given device, and
print out any combination of: the total number of defects, the primary
