Looking at the output from 'camcontrol devlist' the last drive seen have "at scbus4 target 63 lun 0" and the first= "at scbus4 target 16 lun 0". If I connect each drawer into separate H241 controllers then all 70 drives = are visible. According to HP documentation the H241 should handle up to 200 physical dri= ves. I've tried reading the ciss driver source code and I can't see any "obvious" limits/adjustable knobs but I might be missing something.... The "target 63" number feels lika a 64-target-limit somewhere. (The first 16 I'm guessing is reserved for logical drives (which we don't u= se) so I'm guessing that's why it starts numbering at 16). (Now I want to connect a second D6020 to the server(s) in question so I can= use the "use two controller cards" solution anymore) --=20 You are receiving this mail because: You are the assignee for the bug.=
