You probably should decide whether to just use SIMPLE (no matter what) or have a list. Since it's a violation of SAM I doubt that there is a way to detect it. > ... > any side effects? or should I make it tunable? As it stands now for FreeBSD, making them all SIMPLE would probably be okay. Linux does that apparently. I'd make it a tunable with the default to SIMPLE. I asked some of the (now NetApp) Engenio engineers, and their arrays' iSCSI implementation *does* handle all of the different tag types. > Thanks Matthew, you made my day! > > No problem. Thank you, actually. I'm starting to work more with iSCSI for my day job which has been an interesting change.
