* Verify that an I/O stress test runs fine by running the following command
on an initiator system after having created two partitions:
where $dev1 and $dev2 are device nodes created by the SRP initiator and go
over different IB connections to the target:
fio --bs=1M --direct=1 --ioengine=sync --verify=meta --rw=write --verify_fatal=1 --verify_async=1 --loops=10 --name=partition1 --filename=/dev/sdb1 --name=partition2 --filename=/dev/sdb2
