Red Hat Enterprise Linux 5.3 Support Notes for HP Integrity Servers

If you plan to connect Fibre Channel storage arrays to HP Integrity servers running RHEL,
you must connect through a Fibre Channel switch. For the BL860c Server Blade, you must
use either the Fibre Channel switch module (AE370A, AE371A, or AE372A) or an external
Fibre Channel switch.
• Correctable hardware events logging configuration
Correctable platform events, such as, single-bit memory errors, are routinely logged into
NVRAM. To ensure errors are logged into the /var/log file, configure the salinfod file
to start at boot.
As root, execute the following:
1. cd /etc/init.d
2. To configure:
chkconfig salinfod on
3. To start salinfod without rebooting:
service salinfod start
• PCI device listing generates large amount of output when using the lspci -v command
The lspci -v command can generate a large amount of output on systems with a large
number of connected devices. This can be avoided by piping the output of lspci to the
head command specifying the desired number of lines of output. For example, to capture
100 lines of output use the lspci -v | head -n 100 command.
• Contiguous memory unavailable on cell-based server causing an MCA
When Linux boots on an HP Integrity mid-range or high-end cellular server with
discontiguous memory, a cell may boot to a state in which it has too little contiguous memory
available and could cause an MCA.
If this occurs, try one of the following methods to resolve the problem:
— Change the memory configuration so that the memory in each cell is equal
— Change the CLM (Cell Local Memory) setting to increase the size of contiguous memory.
— If the system was working previously, at the EFI prompt, run the pdt command. If
there are PDT entries, consider replacing the bad memory identified.
Software
• 32-bit emulation and other 32-bit functionality
The 32-bit emulation is not automatically installed with RHEL 5.3. To obtain this functionality,
install the ia32el package from the Red Hat Enterprise Linux 5 Supplementary CD.
You can install any additional compatibility binaries needed from the Red Hat Enterprise
Linux 5 Supplementary CD. For instructions, see the Red Hat Enterprise Linux 5 Release Notes
as described in “Installation Documentation” (page 8).
• Use of the cdrecord program
The cdrecord program may hang when burning a CD-RW disk with unsupported media
using certain models of CD/DVD combo and DVD+RW drives shipped in rx1600, rx1620,
rx2600, 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.
In addition, when using cdrecord to burn a disc, you may need to eject the disc and reinsert
before you can mount it.
