Dear All:
I download the new nvme multipath version (git clone
git.infradead.org/nvme.git),I want to know how to use the
multipath, because I want use udev to Persistent Storage,But
when use scsi_id command not found any messages.
What method can nvme achieve multi-path? Can you provide an
example? Thank you
