Linux(Fedora,Red Hat,SuSE) Driver Support
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/rr26xx/.
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/rr26xx/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 RR26xx controller), you can update the driver as below:
# cp rr26xx.ko /lib/modules/‘uname –r‘/updates/
# mkinitrd ‘uname –r‘
For FC2, the commands should be
# cp rr26xx.ko /lib/modules/‘uname –r‘/kernel/drivers/scsi/
# mkinitrd –-preload scsi_mod –-preload sd_mod –-with=rr26xx /
boot/initrd-‘uname –r‘.img ‘uname –r‘
Updating the Driver
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 (rr26xx.o or rr26xx.ko)
