SCSI Kernel Parameters ~~~~~~~~~~~~~~~~~~~~~~ See Documentation/kernel-parameters.txt for general information on specifying module parameters. This document may not be entirely up to date and comprehensive. The command "modinfo -p ${modulename}" shows a current list of all parameters of a loadable module. Loadable modules, after being loaded into the running kernel, also reveal their parameters in /sys/module/${modulename}/parameters/. Some of these parameters may be changed at runtime by the command "echo -n ${value} > /sys/module/${modulename}/parameters/${parm}". advansys= [HW,SCSI] See header of drivers/scsi/advansys.c. aha152x= [HW,SCSI] See Documentation/scsi/aha152x.txt. aha1542= [HW,SCSI] Format: <portbase>[,<buson>,<busoff>[,<dmaspeed>]] aic7xxx= [HW,SCSI] See Documentation/scsi/aic7xxx.txt. aic79xx= [HW,SCSI] See Documentation/scsi/aic79xx.txt. atascsi= [HW,SCSI] Atari SCSI BusLogic= [HW,SCSI] See drivers/scsi/BusLogic.c, comment before function BusLogic_ParseDriverOptions(). dtc3181e= [HW,SCSI] eata= [HW,SCSI] fd_mcs= [HW,SCSI] See header of drivers/scsi/fd_mcs.c. fdomain= [HW,SCSI] See header of drivers/scsi/fdomain.c. gdth= [HW,SCSI] See header of drivers/scsi/gdth.c. gvp11= [HW,SCSI] ibmmcascsi= [HW,MCA,SCSI] IBM MicroChannel SCSI adapter See Documentation/mca.txt. in2000= [HW,SCSI] See header of drivers/scsi/in2000.c. ips= [HW,SCSI] Adaptec / IBM ServeRAID controller See header of drivers/scsi/ips.c. mac5380= [HW,SCSI] Format: <can_queue>,<cmd_per_lun>,<sg_tablesize>,<hostid>,<use_tags> max_luns= [SCSI] Maximum number of LUNs to probe.

Also settable via sysctl at dev.scsi.logging_level (/proc/sys/dev/scsi/logging_level). There is also a nice 'scsi_logging_level' script in the S390-tools package, available for download at http://www-128.ibm.com/developerworks/linux/linux390/s390-tools-1.5.4.html scsi_mod.scan= [SCSI] sync (default) scans SCSI busses as they are discovered. async scans them in kernel threads, allowing boot to proceed. none ignores them, expecting user space to do the scan. sim710= [SCSI,HW] See header of drivers/scsi/sim710.c. st= [HW,SCSI] SCSI tape parameters (buffers, etc.) See Documentation/scsi/st.txt. sym53c416= [HW,SCSI] See header of drivers/scsi/sym53c416.c. t128= [HW,SCSI] See header of drivers/scsi/t128.c. tmscsim= [HW,SCSI] See comment before function dc390_setup() in drivers/scsi/tmscsim.c. u14-34f= [HW,SCSI] UltraStor 14F/34F SCSI host adapter See header of drivers/scsi/u14-34f.c. wd33c93= [HW,SCSI] See header of drivers/scsi/wd33c93.c. wd7000= [HW,SCSI] See header of drivers/scsi/wd7000.c. |
