Is it possible to manually configure two Infiniband ports to operate with one another in back-to-back mode, without running OpenSM on one of them?
We have done this on other IB implementations by manually assigning LIDs, but I discover that the "lid" entry below /sys/class/infiniband/<device> is not writable, at least for mthca. Also, I expect that the ipoib driver will be unable to join the broadcast group, so will be unwilling to come up fully. With ethernet, and maybe iWARP, just a simple ifconfig can do this. So why not IB? If you're wondering, my goal is give NFS/RDMA users a way to avoid having to install the many userspace modules needed to do this, including libibverbs, opensm, etc. There's a lot to get wrong, and things go missing. Seeking an "easy" way to get started with just the kernel and some shell commands.
