Support Notes for SUSE LINUX Enterprise Server 10 Service Pack 4 for HP Integrity Servers (5900-0402)
To power on hardware that has been powered off, use the PE command at the management
processor command menu. To make an inactive nPartition active, use the management
processor BO command to boot the nPartition past the boot-is-blocked state.
8. HP supports up to two I/O chassis per hard partition for the rx7620 and HP Integrity
Superdome SX1000. HP supports up to four I/O chassis per hard partition for the rx8640.
9. SCSI errors and resets for any reason cause system failures. For example, if your disks have
a problem such as a parity or disk error that causes a SCSI reset, the system will fail.
Combining a Seagate drive with the ds2100 disk carrier causes electrical problems on the
SCSI bus and subsequent reset attempts that also result in system failure. Do not use Seagate
drives with this disk carrier.
10. A package will fail to install if the system clock is not set properly. Ensure the system clock
is set properly before attempting any installs.
11. Do not run the "Test X Configuration" when installing the system. It triggers the start of a
second X server, which when saving or restoring fonts causes an MCA. Upon completion
of installation, the user should upgrade the xorg-x11-server package by either downloading
the recommended update from the patch support database, or installing it from YOU. This
update will resolve this problem.
12. SLES10 SP4 obsoletes mii_tool, preventing the user from being able to query a Tulip-based
network card such as the A5506B.
13. The autoinst.xml file written by YaST after installation will format drives even if they were
not touched during the installation of the system. The user should take care to modify this
file to handle their hard disks appropriately before attempting to use the file.
14. The cdrecord program may hang when burning a CD-RW disk with unsupported media
using certain models of CD/DVD-ROM Combo and DVD+RW drives shipped in rx1620,
rx2620, and rx4640 servers.
Use only approved HP CD-RW media to prevent burn hangs. Try different brands of media
if HP media is not available.
15. The ELILO bootloader can pass command-line options to the Linux kernel. The max_addr=
and mem= options limit the amount of memory used by the kernel.
Some versions of the kernel handle these arguments incorrectly, resulting in an MCA that
crashes the system during boot. If the system boots successfully, there is no risk of a crash
due to this problem.
Booting with max_addr= or mem= is sometimes useful for debugging problems, but is not
a tested feature. A similar effect can be achieved by deconfiguring (with the EFI dimmconfig
command) or physically removing DIMMs.
16. System panics may occur on Integrity servers running Linux that have fibre channel (FC)
storage arrays directly connected.
If you plan to connect FC storage to Integrity Servers running Linux, you must connect
through a FC switch. For the BL860c Blade servers, customers must use either the FC switch
module (AE370A/AE371A/AE372A) or an external FC switch.
17. After installing the operating system, if a message similar to the following is displayed, you
will need to take action.
Loading.: SUSE Linux Enterprise Server Load of SUSE Linux Enterprise
Server SP4 failed: Not Found Press any key to continue
To resolve this problem, enter the following commands:
# reconnect -r
# map -r
Next, reboot. This can be done by exiting the shell (using the exit command) and reselecting
the EFI boot menu entry.
