SubjectRe: Linux Cluster using shared scsi

That's not within my gift. I can merely write the code that corrects the
behaviour. I can't force anyone else to accept it. said:

Use of reservations is laid out in the SCSI-2 and SCSI-3 standards (which can
be downloaded from the T10 site which are international in scope.
I think the implementation issues come because the reservations part is
really only relevant to a multi-initiator clustered environment which isn't an
every day configuration for most Linux users. Obviously, as Linux moves into
the SAN arena this type of configuration will become a lot more common, at
which time the various problems associated with multiple initiators should
rise in prominence.
