HP XC System Software Administration Guide Version 3.2

1. Use the systemconfigurator command as follows:
# /usr/bin/systemconfigurator -runboot -stdin <<EOF
[BOOT]
BOOTDEV = disk1
BOOTDEV2 = disk2
EOF
NOTE: Be sure to use the appropriate disk drive device name for the disk1 and disk2
parameters. For example, for IDE disks, the values could be /dev/hda and /dev/hdb,
respectively.
2. Adjust the boot order:
# /tmp/post-install/50all.bootorder.pl
NOTE: If this file was deleted from the client, you can find it on the head node in
/var/lib/systemimager/post-install/50all.bootorder.pl file.
For CP4000 Systems
You need to update the boot order using the GRand Unified Bootloader, also known as grub.
Enter a command like the following. If you do not use IDE disks /dev/hda and /dev/hdb for
your boot disk, you need to adjust this command.
# grub --no-floppy --no-curses <<EOF
root(hd0,0)
setup(hd0)
device(hd0)/dev/hdb
root(hd0,0)
setup(hd0)
EOF
In this example, the first instance of root and setup apply to the first disk; /dev/hda and the
second instance of root and setup apply to the second disk, /dev/hdb.
22.6 Incorporating External Network Interface Cards
NOTE: Recabling the NICs is required for their physical installation. If you decide to reposition
a NIC on the node, additional recabling will be required.
The following section describes how to incorporate external network interface cards (NICs) on
the following cluster platforms:
• HP CP3000 (Intel Xeon)
• HP CP4000 (AMD Opteron)
• HP CP6000 (Intel Itanium 2)
These cluster platforms are described in the HP XC Hardware Preparation Guide.
IMPORTANT: The node or nodes that receive additional network interface cards will be
unavailable for a period of time while they are reimaged.
You need to perform these necessary tasks to incorporate external NICs:
• “Gathering Information” (page 276)
• “Editing the platform_vars.ini File” (page 279)
• “Using the device_config Command” (page 283)
• “Updating the Database for the External Network Card” (page 283)
• “Updating the Firewall Custom Configuration” (page 284)
