When I run ibdmchk with LMC=1 on my cluster it is failing with below
warnings.

------------------ NUM ALTERNATE PORTS TO CA HISTOGRAM --------------------
Describes how many out ports on every switch have the same Min Hop to each
target CA. Or in other words how many alternate routes are possible at the
switch level. This is useful to show the symmetry of the cluster.

OUT-PORTS NUM-SW-LID-PAIRS
---------------------------------------------------------------------------

-W- Found - un-reachable lids.
-E- Fail to update Min Hops Tables.
<=================================================>


Can anyone of you explain me what do they mean?

(Please find contents of osm.fdbs, osm-subnet.list and complete output
of the ibdmchk in the attachments.)
