What I need to do is this: # My new CX3-40f which supports ALUA (preferred) as well as PNR device { vendor DGC product * product_blacklist LUNZ alua_capable yes [..ALUA optimised settings...] } # My old CX200, only supports PNR device { vendor DGC product * product_blacklist LUNZ alua_capable no [..PNR optimised settings...] } ...but there's no such thing as the "alua_capable" setting or any other setting that can be used to distinguish between the two CLARiiONs, as far as I know, so I have to use both arrays in PNR mode even though the newest one of them supports ALUA.
No need. I did some patch once ago which allowed you to set the hardware handler in the multipaths section. For exactly this scenario. Can you test if it works?
