Same issue as ECKD. An OS cannot tell what other OSes/LPARs have access to an ECKD dasd volume. We simply ignore the issue and put the burden on the "hardware people" to limit access. We're lucky in that we generally trust the accessing systems. A naive trust, perhaps, but still.... My issue is that I don't understand the job of the SAN storage administrator well enough to judge how hard is is to implement strict zoning and LUN masking rules. They have orders of magnitude more devices to deal with.
