Yes, you're right, and I think I didn't define correctly the maximum value, I use 31 instead of 32 as explained in include/scsi/scsi_host.h:
/* * These three parameters can be used to allow for wide scsi, * and for host adapters that support multiple busses * The last two should be set to 1 more than the actual max id * or lun (e.g. 8 for SCSI parallel systems). */ unsigned int max_channel; unsigned int max_id; u64 max_lun;
