We would like to use newer opensm (eg. OFED 3.5) with older connectx HCA on linux hosts. The connectx adapters have the latest firmware (version 2.8). However the new opensm seems to require a non-default partition/partition key to work with these cards. Has any had luck using OFED-3.x with the older mellanox adapters ?
How did you figure out the issue with the non-default partition/partition key?
can you share the following:
Which opensm version are you using?
any flags/configuration files used with opensm?
