            Bug ID: 271238
           Summary: mpr (LSI SAS3816) driver not finding ses devices in HP
                    D6020 enclosures
           Product: Base System
           Version: 12.4-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: pen@lysator.liu.se

For some reason the mpr driver doesn't seem to correctly locate the SES dev=
ices
in the HP D6020 external SAS enclosures although "mprutil" sees them.

ses2 at ahciem0 bus 0 scbus6 target 0 lun 0
ses3 at ahciem1 bus 0 scbus11 target 0 lun 0

(ses0 & ses1 are also SES devices in another D6020 enclosure which is attac=
hed
via an HP H241 "ciss" HBA adapter instead of the "mpr" (SAS3816). ses2 & se=
s3
are internal ses units on the server)

One suspect thing is the "T" 33 & 69 which seems to be the SES units, which
also seems to collide with disks (see the gaps in the listing). All disks a=
re
showing up though via camcontrol and are usable.

Any ideas?
