1. Save the original firmware files in /lib/firmware:
# cd /
# cp /lib/firmware/ql2400_fw.bin /lib/firmware/ql2400_fw.bin.orig
# cp /lib/firmware/ql2500_fw.bin /lib/firmware/ql2500_fw.bin.orig
2. Use the following commands to extract the firmware:
# rpm -Uvh --force ql2400-firmware-x.yy.zz.noarch.rpm
$ rpm -Uvh --force ql2500-firmware-x.yy.zz.noarch.rpm
3. Rebuild the ramdisk, and then reboot.
# mkinitrd -i initrd.img –k kernelimage
NOTE: A SLES11 SP2 scheduler issue is observed in BFS configurations during heavy IO load.
In BFS configuration, HP recommends to change the default scheduler Completely Fair Queuing
(CFQ) to the other scheduler options such as noop or deadline. To change the scheduler, edit the
boot loader configuration file
/boot/grub/menu.lst
. Add elevator=deadline or elevator=noop to the kernel entry and reboot the system. Check the
elevator settings with the command
cat/sys/block/sdb/queue/scheduler.
/boot/grub/menu.lst
