HP StorageWorks X5500 Network Storage Gateway for Linux setup guide (AP811-96003, October 2009)

A Building a custom kernel
This appendix contains the following procedures for SLES10 installations:
• Compile a third-party kernel module
• Extract HP X5500 Storage Gateway for Linux kernel patches
• Rebuild the entire kernel from source
SLES10
Compile a third-party kernel module
In general, third-party kernel modules are compiled using a skeletal kernel source tree and pre-computed
symbols for the specific kernel configuration they will be loaded into. To set up this expected build
environment, you will need to install the following RPMs (from the pmxs-kernels rpm):
• The kernel binary RPM:
kernel-HPPS-2.6.16.60–0.21.370.<xxxx>.<arch>.rpm
• The kernel architecture-specific source RPM:
kernel-source-2.6.16.60–0.21.370.<xxxx>.<arch>.rpm
After installing the RPMs, reboot on the new binary kernel and verify that uname -r reports
2.6.16.60–0.21–HPPS. If desired, edit the default setting in /boot/grub/menu.lst to select
the new kernel automatically. The newly installed kernel will be the first entry in the list (default=0).
If everything is set up properly, the symlink:
/lib/modules/2.6.16.60–0.21.370.<xxxx>-HPPS/build
will point to:
/usr/src/linux/2.6.16.60–0.21.370.<xxxx>-obj/<arch>/HPPS
and the symlink:
/lib/modules/2.6.16.60–0.21.370.<xxxx>-HPPS/source
will point to:
/usr/src/linux/2.6.16.60–0.21.370.<xxxx>
The environment is now ready to support compilation of third-party kernel modules. Refer to the
documentation provided with the module for installation, configuration and build process information.
Extract HP X5500 Storage Gateway for Linux kernel patches
Compiling third-party software using the HP X5500 Storage Gateway for Linux installed kernel build
environment, as described in the previous section, is a preferred technique. However, there may be
cases where you must extract the HP X5500 Storage Gateway for Linux kernel patches so they can
be integrated into your custom build environment.
