Linux Configuration
The valid Linux kernel to deploy to the servers needs to be certified with
the SAP LinuxLab and at the same time needs to be supported with HP
Serviceguard Extension for SAP on Linux.
The SAP LinuxLab publishes kernels to deploy on its FTP server. The
latest kernel to deploy can be obtained from SAP. Instructions from
where to download these kernels can be found on
http://www.sap.com/linux/. Additional information on how to contact
the SAP LinuxLab can also be found there.
All supported Serviceguard Extension for SAP on Linux setups were
tested with drivers that are supported by HP Serviceguard for Linux and
at the same time are part of an SAP certified Linux distribution. For
these setups, it is not required to install any driver in addition to those
that come with the Linux distribution. LVM, network bonding and
multi-pathing are supported via the software that comes with the Linux
distribution.
Activities that would endanger SAP support are:
• Recompiling/remaking the Linux kernel after installation.
• Adding drivers that are not part of the installed Linux distribution.
• Adding kernel modules that are not delivered with an open source
license.
