Issues and Known Problems
Chapter 114
If CLM is greater than one percent of installed memory, use the parmodify command with
the -m parameter to specify the CLM value, which should be 0 for Linux partitions.
Alternately, you can also run the parremove command to remove the nPartition, then run
the parcreate command to create a new nPartition with zero percent CLM. See the HP
System Partitions Guide for detailed information on configuring an nPartition.
14. The Red Hat Enterprise Linux AS v.3 Update 3 kernel supports maximum memory of 128
GB, which is also supported by HP.
15. Correctable platform events such as single-bit memory errors are routinely logged into
NVRAM. The Red Hat operating system continues to print diagnostic messages about
such events on both the system console and in the file /var/log/messages until the event
is cleared.
You must clear the event manually by running the following command as root:
Type echo clear 0 > /proc/sal/cpe/data and press
Enter.
16. If you use cdrecord to burn a CD, you may need to eject the CD and reinsert before you
can mount it.
17. Inconsistencies with man page directions for editing /etc/fstab.
If you manually edit the /etc/fstab file to alter the device partition to be mounted as
swap space, follow the fstab man page directions. The swapon manpages incorrectly
describe swap filesystem entries in /etc/fstab as being labeled with"sw" when they
should be labeled "swap". swapon will not throw an error if it encounters an invalid swap
entry in /etc/fstab.
