HP XC System Software Release Notes for Version 3.1

/var/lib/systemimager/images/base_image/boot/grub/grub.conf
2. Add the noapic option to the end of the kernel boot options as follows:
#boot=/dev/cciss/c0d0
default=0
timeout=5
hiddenmenu
title Linux for High Performance Computing 4 (Savant) (2.6.9-34.4hp.XCsmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-34.4hp.XCsmp ro root=LABEL=/ console=ttyS2 noapic
initrd /initrd-2.6.9-34.4hp.XCsmp.img
3. Save your changes and exit the text editor.
• If the hardware configuration contains one or more HP ProLiant DL145 Generation 2 nodes,
add the additional kernel boot option noapic to the grub.conf file as an override to the
system image. The HP XC System Software Administration Guide describes how to overwrite
files delivered in the golden image.
5.8.5 Increase the Imaging Time Out Limit on Systems With Large Disks
If the system contains disks that are 250 GB or larger in size, you may need to increase the 45
minute default allowed for imaging by the startsys command.
For example, on systems with disks larger than 250 GB, the --image_timeout=n option of
startsys is set to 60 to increase the image time out limit. You might use a different value
depending upon the size of the disks in the system.
# startsys --image_and_boot --image_timeout=60
5.8.6 Edit the /etc/dhcpd.conf File
Perform this task only if the system is using a Myrinet interconnect and you followed the
instructions in “Save the Contents of the /etc/dhcpd.conf File” (page 42) to save a backup copy
of the /etc/dhcpd.conf file:
1. Use the text editor of you choice to open the /etc/dhcpd.conf file.
2. In another terminal window, use the text editor of your choice to open the
/etc/dhcpd.conf.ORIG file.
3. Merge the customizations you made to the backup copy of the file when you configured the
switch monitoring line cards into the /etc/dhcpd.conf file.
IMPORTANT: Do not replace the newly-created /etc/dhcpd.conf file with the entire
contents of the .ORIG backup copy because the new version of the /etc/dhcpd.conf file
may contain new or additional information that is not present in the backup copy.
4. Save your changes to the /etc/dhcpd.conf file and exit the text editors.
5. Restart the dhcpd service:
# service dhcpd restart
