[openib-general] opensm problem

[Hal Rosenstock]

Steve,
 
Those messages mean that you are joining a MC group which is not already created. The MGID iof 0xff12401bffff0000 : 0x0000000000000016 is for 224.0.0.22. That is for IGMP on your IPoIB subnet. The group either needs to be preconfigured or the "first" joiner needs to create the group (which requires more characteristics).
 
OpenSM already precreates some groups but not this one. This can be added easily. Can it wait until next week ?

I'm using 2.6.19-rc5 + sean's ucma patch series plus the latest
userspace/management code from svn.  I'm running mthca point to point
between two servers.  When I start opensm, it continually logs these
messages:

Nov 16 14:15:15 567111 [42003940] -> __osm_mcmr_rcv_join_mgrp: ERR 1B11: method = SubnAdmSet, scope_state = 0x1, component mask = 0x0000000000010083, expected comp mask = 0x00000000000130c7, MGID: 0xff12401bffff0000 : 0x0000000000000016 from port 0x0002c902002147c9

I think this is some sort of mismatch between the mcast code in seans patch series and the management code maybe?

Anybody seen this?

Thanks,

Steve.
