Linux drivers can support the local changing of the SM NodeDescription attribute which is what is used in the absence of a node name map to supply this information. I'm presuming the latter is not the case. As a related side note, changing the NodeDescription is supposed to also trigger a trap 144 for other local changes (so the SM can detect this change as well). -- Hal > Do you know why the WIndows driver supplies only the HCA name where the > Linux HCA driver supplies the actual hostname (as in output from the > hostname cmd) plus the HCA name? > > How difficult would it be to correct the Windows HCA drivers to supply the > Hostname in addition to the HCA name? > > thanks, > > stan. > > > # > # Topology file: generated on Tue Feb 16 17:00:30 2010 > # > # Initiated from node 0002c9020000409c port 0002c9020000409d > > vendid=0x2c9 > devid=0xb924 > sysimgguid=0x2c9010a7cd2b0 > switchguid=0x2c9010a7cd2b0(2c9010a7cd2b0) > Switch 24 "S-0002c9010a7cd2b0" # "MT47396 Infiniscale-III Mellanox > Technologies" base port 0 lid 5 lmc 0 > Linux--> [1] "H-0002c9020000525c"[1](2c9020000525d) # "srpt > HCA-1" lid 9 4xSDR > Windows--> [2] "H-0002c90107fc56a0"[1](2c90107fc56a1) # "MT23108 > InfiniHost Mellanox Technologies" lid 4 4xSDR > [5] "H-0002c9020000409c"[1](2c9020000409d) # "MT25208 > InfiniHostEx Mellanox Technologies" lid 2 4xSDR > [11] "H-0002c9030000a5b4"[1](2c9030000a5b5) # "MT25408 ConnectX > Mellanox Technologies" lid 10 4xSDR > [13] "H-0002c9030000bff8"[1](2c9030000bff9) # "MT25408 ConnectX > Mellanox Technologies" lid 11 4xSDR > [19] "H-0002c90200004f98"[1](2c90200004f99) # "MT25208 > InfiniHostEx Mellanox Technologies" lid 13 4xSDR > > _______________________________________________ > ofw mailing list > [email protected] > http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw > _______________________________________________ ofw mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw
