Here are the steps to set the mpt2sas driver logging level a.While loading the driver modprobe mpt2sas logging_level=0x3f8 b. If driver is in ramdisk, then in RHEL5/SLES/OEL5 OS, following line has to be added in /etc/modprobe.conf and reboot the system options mpt2sas logging_level=0x3f8 (Or) Add below word at the end of kernel module parameters line in /boot/grub/menu.lst or /boot/grub/grub.conf file and reboot the system mpt2sas.logging_level=0x3f8 c. During driver run time echo 0x3f8 > /sys/module/mpt2sas/parameters/logging_level Also please provide us the IO rate at which you are faceing this problem.
