Chapter 15. SAS configuration 2 - Linux host 337
Draft Document for Review August 30, 2007 12:59 am 7065SAS_Config2.fm
The source files will be unpacked in the linuxrdac-09.01.B5.39 subdirectory of the current
directory. When the uncompress is complete, change to this subdirectory.
2. Use the following command to remove old driver modules:
make clean
3. Compile the driver modules and build the RDAC driver. Use this command:
make
15.4.2 Install the RDAC driver
We need to copy the driver modules to the kernel module tree and build the new RAMdisk
image which includes the RDAC driver modules. Enter:
make install
This will produce a lengthy output in the console window, as the driver modules are applied to
the kernel tree. The last few lines will tell you how to add the new boot menu option to the
boot loader, as shown in Example 15-1.
Example 15-1 RDAC installation
Creating new MPP initrd image...
You must now edit your boot loader configuration file, /boot/grub/menu.lst, to
add a new boot menu, which uses mpp-2.6.9-34.ELsmp.img as the initrd image.
Now Reboot the system for MPP to take effect.
The new boot menu entry should look something like this (note that it may
vary with different system configuration):
...
title Red Hat Linux (2.6.9-34.ELsmp) with MPP support
root (hd0,5)
kernel /vmlinuz-2.6.9-34.ELsmp ro root=LABEL=RH9
initrd /mpp-2.6.9-34.ELsmp.img
...
MPP driver package has been sucessfully installed on your system.
The new RAMdisk image filename is mpp-2.6.9-34.ELsmp.img. So we have to add the
following to the menu.lst file, as shown in Example 15-2:
Example 15-2 Modify menu.lst file
title Red Hat Linux (2.6.9-34.ELsmp) with MPP support
root (hd0,1)
kernel /vmlinuz-2.6.9-34.ELsmp ro root=LABEL=/1 pci=nommconf rhgb quiet
initrd /mpp-2.6.9-34.ELsmp.img
We now restart the system using the new boot option.
15.4.3 Verification steps
When the server restarts, use the lsmod command to verify that the RDAC (MPP) modules
are running. The following modules should be listed:
򐂰 mppUpper
򐂰 mppVhba
