Hello blktests users, As of today, software RDMA driver "siw" or "rdma_rxe" is used to run "nvme" group with nvme_trtype=rdma or "srp" (scsi rdma protocol) group. Now it is suggested to run the test groups with real RDMA hardware to run tests in more realistic conditions. A GitHub pull request is under review to support it [1]. If you are interested in, please take a look and comment. [1] https://github.com/osandov/blktests/pull/86
When I wrote the SRP tests, my goal was to test the SRP initiator driver, SRP target driver and dm-multipath drivers and also to allow users who do not have RDMA hardware to run these tests. Running these tests against a real RDMA adapter tests other functionality than block layer code. I see this as a use case that falls outside the original scope of the blktests test suite. Running NVMe tests against a real storage array also falls outside the scope of testing block driver functionality. I'm fine with adding this functionality but I hope that it does not become a burden for blktests contributors who are not interested in maintaining functionality that falls outside the original scope of blktests.
