I knew these pdfs already, and thats what I basically did. This information does not help me much, when something does not work.

How can I control that a volume has persistent reservations? Because obviously with all but one the cluster test complains about missing SPC-3. Is there a difference btw SCST or IET?

If SPC-3 reservations should always work, is there a certain problem that could break such a design? Is MPIO in any kind a problem?

Thanks Jens
