The peripheral qualifier bits of the inquiry response are set to indicate
the state of the lun as either connected, offline, or not addressable.
The connected state does not indicate that the device is ready to be
accessed, but the probe code should not be responsible for this

FreeBSD's probe code has probed high luns without using a TUR for over
three years now. It is not required and, as Gerard has mentioned, can
be harmful.
