Frank, host->max_id (max scsi target ID's) is set to TW_MAX_UNITS_9650SE for your adapter, which is 32. The firmware srl (spec revision level) for your 9650 adapter doesn't support luns > (0 .. 16). You could run in this mode but it hasn't been tested, and I don't recall what the ramifications may be (if any). -Adam On Tue, Aug 28, 2018 at 10:02 AM Randy Dunlap <rdunlap@xxxxxxxxxxxxx> wrote: > > [add linux-scsi list] > > On 08/28/2018 05:23 AM, Frank Kammer wrote: > > Hello, > > > > I have a 3ware 9650SE RAID-Controller with 20 LUNs.
