Hi, so far we always did run opensm without the --lmc option, but just recently I read in opensm's manpage about it.
<opensm manpage> This option specifies the subnet's LMC value. The number of LIDs assigned to each port is 2^LMC. The LMC value must be in the range 0-7. LMC values > 0 allow multiple paths between ports. LMC values > 0 should only be used if the subnet topology actually provides multiple paths between ports, i.e. multiple interconnects between switches. Without -l, OpenSM defaults to LMC = 0, which allows one path between any two ports. </opensm manpage> In one of our configurations we do have a mts2400 (master) switch and connected to it are two mts14400 switches (each with 3 connections to the the mts2400). I think from the description of the opensm manpage we need to give the "--lmc" to make use of the 3 connections from each mts14400 switch to the mts2400 switch, don't we? Furthermore, from manpage I would think we even need this option for proper inter-communication between the switch modules?
