Defining Nodes - IBM eserver Cluster 1350 Installation And Service Manual

3. For Red Hat Linux version 9, rebuild the two initrd images. You can not make a
4. If a Remote Supervisor Adapter is installed, restart and run the setup diskette or
5. If you have custom modifications, configure the kernel.
6. Reboot the node.

Defining nodes

Before you can distribute the system image to all nodes in the Cluster 1350, you
must first define the nodes for which you do not know the IP addresses.
Defining nodes using CSM
You can use a node-definition file to define the nodes, console servers, and service
processors to the cluster, or you can enter the information from the command line.
1. To define the nodes, console server information, and service processors, type
2. To review the arguments that you need to enter from the command line, type
3. To define the node host name, type
See the IBM Cluster Systems Management for Linux Technical Reference for
details about definenode and addnode command-line syntax and more examples of
the usage of the command.

alias scsi_hostadapter4 aic7xxx
alias scsi_hostadapter5 qla2x00
alias usb-controller usb-ohci
options scsi_mod max_scsi_luns=128
For SUSE Linux 8.2 and SLES8: edit the /etc/modules.conf file so that it
contains the following lines:
alias scsi_hostadapter ips
alias scsi_hostadapter1 qla2300
options scsi_max_scsi_luns=128
For SUSE Linux 8.2, append the /etc/sysconfig/kernel file with the following line:
INITRD_MODULES="ips qla2300 reiserfs"
For SLES8, edit the /etc/rc.config file to contain the following line:
INITRD_MODULES="ips qla2300"
RAM disk image if mkinitrd detects one already present with the same name, so
the first two commands will rename the old images. For example:
mv /boot/initrd-2.4.2-2.img /boot/initrd-2.4.2-2_orig.img
mv /boot/initrd-2.4.2-2smp.img /boot/initrd-2.4.2-2smp_orig.img
mkinitrd initrd-2.4.2-2.img 2.4.2-2
mkinitrd initrd-2.4.2-2smp.img 2.4.2-2smp
For SUSE 8.2 and SLES8, type the mkinitrd command to create a boot/initrd
directory, and then run lilo.

definenode -n hostname
where hostname is the name of the node being defined. The command prompts
for missing information when some or all of the arguments are not provided.
