Support Notes for SUSE Linux Enterprise Server 11 Support Pack 2 for HP Integrity Servers

3 Recommendations, Limitations, and Known Issues
This chapter contains recommendations, limitations, and known issues with the use of SLES 11 SP2
on HP Integrity servers.
Recommendations
The following recommendations from HP for using SLES 11 SP2 on HP Integrity servers should be
observed.
• Review the SLES 11 SP2 release notes
HP encourages you to review the Novell Release Notes for SUSE Linux Enterprise Server 11
for the current status on items such as the Reiserfs filesystem at the Novell SLES 11
documentation website:
http://www.novell.com/documentation/sles11/index.html
• Upgrading from earlier SLES versions
The only recommend upgrade method from one SLES distribution to another is to execute a
full cold installation. This is the only upgrade path supported by HP.
• Use of LSI 1068 controller onrx2660 servers
If you are upgrading from SLES 10 on an existing rx2660 server or purchasing one of these
servers, HP does not recommend the use of the LSI 1068 controller with SLES 11 SP2. There
is no remote monitoring support available for the LSI 1068 controller with SLES 11 SP2 so HP
recommends the use of any of the other Fibre Channel HBA or Smart Array controllers.
• Reduce installation time on systems with numerous LUNs (storage)
While the number of LUNs for a running system is virtually unlimited, HP recommends that
you do not have more than 64 LUNs online during the SLES 11 SP2 installation to reduce the
time to initialize and scan the devices thus reducing the installation time.
Limitations
The following section describes the limitations of SLES 11 SP2 on HP Integrity servers.
• Uncertified RPM packages support
If you add uncertified RPM packages to the operating system (for example, from an open
source development repository), it will not be supported by Novell. Only RPM packages
bundled in supported Linux distributions for HP Integrity servers and official SLES Service Packs
for those distributions are supported by Novell . HP supports only the Linux software it
distributes.
• Systems with a recompiled kernel support
Although you may recompile your kernel to change configuration parameters, HP does not
support systems on which you have recompiled your kernel for any other reason. For example,
for kernel source code changes.
The following are the only supported customizations:
— Modifying configuration options found in /usr/src/
linux-version-versionnumber/configs to set values or make modules static or
dynamically loadable.
— Changing boot parameters found in /usr/src/linux/Documentation/
kernel-parameters.txt (with the kernel-source /rpm).
