Multi-initiator discussions come up every other month, but the answer as to
whether or not the multi-initiator configs are a good idea flip/flops.
The discussions around 14 June indicated that because the mid-layer doesn't
handle reserves and reset wars, multi-initiator configs are a bad idea on
Linux and are exposed to data corruption. Since the same mid-layer is used
for FC, there are multi-initiator issues in SANs as well.
I understood multi-initiator configs are at risk until Linux drivers (and
devices) implement the SCSI-3 persistent reserves and ACA.
This time around the discussion is indicating a different story.
Are multi-initiator SCSI/FC configs a robust, recommended topology or not?
I'm not looking for the anecdotal "works for me", I'm asking from a driver
design perspective.
