I'm no expert on this bit but look in drivers/scsi/scsi_scan.c for CONFIG_SCSI_MULTI_LUN
#ifdef CONFIG_SCSI_MULTI_LUN static int max_scsi_luns = 8; #else static int max_scsi_luns = 1; #endif
This is the variable you seem to want.
Note to SCSI maintainers. a quick vi `grep -l CONFIG_SCSI_MULTI_LUN` here reveals lots of hardcoded values of 8. It seems to me that perhaps a CONFIG_SCSI_MAX_LUN to replace CONFIG_SCSI_MULTI_LUN would be in order.
I know Alan and others are planning to do major cleanup of the scsi subsystem (hopefully after IDE stablizes?)
