[ofa-general] Bug in opensm LID assignement

Thu May 7 07:09:39 PDT 2009

opensm assigns conflicting LIDs to node after lmc change (e.g. 0 to 1)
when node guid is in the guid2lid cache.

In the following example CA port 1 lid 24 lmc 1
and switch lid is 25 which overlaps with CA port's lid.
This happens because switch port guid is in the guid2lid cache (0x0008f104003f2aa2 0x0019 0x0019)

vendid=0x2c9
devid=0x634a
sysimgguid=0x2c902002576a3
caguid=0x2c902002576a0
