Support Notes for SUSE LINUX Enterprise Server 10 Service Pack 1 for HP Integrity Servers

included in the documentation package that is posted with the driver. The fixed driver will
be included in the next Service Pack for SUSE Linux Enterprise.
Even with the fixed tg3 driver the system may not establish a link 100 percent of the time
because of a hardware problem. This is an issue that manifests itself on Linux and does not
affect other operating systems. Until this issue is resolved, if the system does not establish
a link, then simply retry the Ethernet operation that failed.
18. 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.
19. 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 SP1 failed: Not Found Press any key to continue
To resolve this problem, enter the following commands:
# reconnect -r
# map -r
Then reboot. This can be done by exiting the shell (using the exit command) and reselecting
the EFI boot menu entry.
20. On SLES 10 Service Pack 1, the CPU frequency scaling subsystem of the kernel (cpufreq) is
enabled by default. Linux uses performance states (P-states) to manipulate a CPU's core
frequency, lowering the frequency when the system is not under load thus reducing the
platform's power consumption. HP's position is that it does not support P-state functionality
on SLES10 SP1 and recommends disabling it.
To disable the frequency scaling subsystem of the kernel, follow these steps:
1. Enter the following command at the EFI shell's command prompt prior to
installing/booting Linux:
EFI> cpuconfig pstates off
2. After entering the cpuconfig command, enter a reset for the disabling of P-states
to take effect.
These steps should be performed prior to installing, and or booting, Linux.
HP expects this issue to be corrected in a future release of SLES 10.
21. When Linux boots on an mid-range/high-end (cellular) IA-64 machine with discontiguous
memory, a cell may end up in a state where it has too little contiguous memory available,
and could cause an MCA.
If you experience this issue, try one of the following methods to resolve the problem:
a. Try changing the memory configuration so that the memory in each cell is equal.
b. Try changing the CLM (Cell Local Memory) setting to increase the size of contiguous
memory.
If the system was working previously, try the pdt command at the EFI prompt. If there are
PDT entries, consider replacing the bad memory.
22. The Kernel Debugger (KDB) is included in SLES 10. When a Transfer of Control (TOC) is
issued, instead of producing a dump, the SLES 10 kernel enters the KDB. This process may
cause issues, and HP recommends that you do not use TOC.
23. Installation of any file system to a SmartArray (particularly if the file system is being used
as root and is xfs) may prevent the reboot of the operating system. To resolve the issue, HP
