It has been a while since using comstar, but the SCSI protocol has
WERO group reservations. Would that suffice?

Yeah, I believe so....question is how I can manage it? It doesn't seem to be a part of stmfadm, so I need to do it elsewhere, if possible...so you, or someone else, got some ideas...?

Hmm, been reading up a little on the PR and WERO....it seems to be registering on DEVICE level, not on LU level, huh? Or do I misinterpret something here...?

There are possibilities to set read only, or r/w, on a LU, but that property is valid for all hosts, it is not(afaik) possible to choose which hosts are going to get read only, and which are going to get r/w.
