Linux Driver Support

6-7

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/.

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

1. If the original driver is installed in the system initrd file (e.g. when OS is installed

to RR3540 controller), you can update the driver as below:

# cp hptiop.ko /lib/modules/‘uname –r‘/updates/

# mkinitrd ‘uname –r‘

For FC2, the commands should be

# cp hptiop.ko /lib/modules/‘uname –r‘/kernel/drivers/scsi/

# mkinitrd –-preload scsi_mod –-preload sd_mod –-with=hptiop /boot/

initrd-‘uname –r‘.img ‘uname –r‘

It’s recommended to backup the original initrd file before you update the driver.

2. If the original driver is installed in the /lib/modules/‘uname –r‘/kernel/drivers/scsi/

directory, and load it by the script file (e.g. /etc/init.d/hptdriver) during the init

process, please replace it with the new driver (hptiop.o or hptiop.ko)
