Linux kernel 2.6.7 on s390. CONFIG_SCSI_LOGGING: This turns on a logging facility that can be used to debug a number of SCSI related problems. If you say Y here, no logging output will appear by default, but you can enable logging by saying Y to "/proc file system support" and "Sysctl support" below and executing the command echo "scsi log token [level]" > /proc/scsi/scsi at boot time after the /proc file system has been mounted. There are a number of things that can be used for 'token' (you can find them in the source: <file:drivers/scsi/scsi.c>), and this allows you to select the types of information you want, and the level allows you to select the level of verbosity. If you say N here, it may be harder to track down some types of SCSI problems. If you say Y here your kernel will be somewhat larger, but there should be no noticeable performance impact as long as you have logging turned off.
