            Bug ID: 224167
           Summary: mps driver masking disk drive behind enclosure
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: bugzillaforfreebsd at mailinator.com

I have a Dell R610 with a H200i (LSI SAS2008) controller in JBOD mode. Under
11.0 the mps driver would always error on the enclosure:

mps0: <Avago Technologies (LSI) SAS2008> port 0xfc00-0xfcff mem

da4 at mps0 bus 0 scbus0 target 7 lun 0
da3 at mps0 bus 0 scbus0 target 6 lun 0

After upgrading to 11.1 the mps driver appears to be masking the last hard
drive with target=8 and so the system no longer detects the sixth hard drive
(da5).
