Then you should inform the system load the module when system boots up with the
following command:
#echo "modprobe hptiop" > /etc/init.d/hptdriver
#chmod 755 /etc/init.d/hptdriver
#ln –sf /etc/init.d/hptdriver /etc/rc.d/rc3.d/S01hptdriver
#ln –sf /etc/init.d/hptdriver /etc/rc.d/rc4.d/S01hptdriver
#ln –sf /etc/init.d/hptdriver /etc/rc.d/rc5.d/S01hptdriver
Step 4 Configure System to Mount Volumes when Startup
Now you can inform the system to automatically mount the array by modifying the file
/etc/fstab. E.g. you can add the following line to tell the system to mount /dev/sda1 to
location /mnt/raid after startup:
/dev/sda1 /mnt/raid ext3 defaults 0 0
4 - Monitoring the Driver
Once the driver is running, you can monitor it through the Linux proc file system
support. There is a special file under /proc/scsi/hptiop/. Through this file you can
view driver status and send control commands to the driver.
Note: The file name is the SCSI host number allocated by OS. If you have no other
SCSI cards installed, it will be 0. In the following sections, we will use x to represent
this number.
Checking Devices Status
Using the following command to show driver status:
# cat /proc/scsi/hptiop/x
This command will show the driver version number, physical device list and logical
device list.
5 - Updating the Driver
First obtain the new driver module file hptiop.o from the driver image. Refer to the
previous section "Obtain the Driver Module". In the following steps, we assume you
have copied it to /tmp/hptiop.ko, and your initrd file is /boot/initrd-`uname –r`.img
1.
If you are not booting from disks attached to RR4320 controller, you can update
the driver just by reinstalling it following the previous section, "Install
