Building the HP SFS client kit manually C–5

d. Add the additional required patches to the kernel.spec file in the same way that you applied

the Lustre patches. See Section 3.2.6 for a list of additional patches.

You can find the additional patches in the src directory; the series file (which lists the

patches) is on the HP StorageWorks Scalable File Share Client Software CD-ROM under the

client_enabler/src/arch/distro/patches/ directory.

The following is an example of the command that you would use to copy the required patches

into the output/src/ directory:

$ for i in $(cat /mnt/cdrom/client_enabler/src/x86_64/RHEL3.0_U7/patches/

client_RHEL3_U7_series);

do cp src/"$i" output/src/; done

e. Modify the kernel.spec file, as follows:

• Set the release to a unique identifier so that this kernel can be easily distinguished from the

standard kernel.

• Turn off all build targets except the build target that is appropriate for your system.

f. Modify the kernel config files as appropriate for your system and your interconnects.

For example, the following settings are required for an x86_64 architecture system with a

Quadrics interconnect:

# Quadrics QsNet device support

CONFIG_QSNET=m

CONFIG_ELAN3=m

CONFIG_ELAN4=m

CONFIG_EP=m

CONFIG_EIP=m

CONFIG_RMS=m

CONFIG_JTAG=m

CONFIG_IOPROC=y

CONFIG_PTRACK=y

# Set the stack size

# CONFIG_NOBIGSTACK is not set

CONFIG_STACK_SIZE_16KB=y

# CONFIG_STACK_SIZE_32KB is not set

# CONFIG_STACK_SIZE_64KB is not set

CONFIG_STACK_SIZE_SHIFT=2

You can find the config files in the output/src directory. (Note that you can generate a

customized and correct config file by following the instructions (provided below) for creating a

built kernel tree.)

g. Build the kernel, by entering the following command:

$ rpmbuild -ba output/specs/kernel.spec

h. Copy the built kernel sources from the output/build to the build/ directory, and fix the

tree, as follows:

$ cp -pr output/build/kernel-2.4.21/linux-2.4.21/ build/

$ cd build/linux/

$ make dep

$ cd ../../
