Install_New_Kernel

Install a new Kernel on the nodes

Using a postinstall script ( you could also use the updatenode method):

mkdir /install/postscripts/data
cp <kernel> /install/postscripts/data

Create the postscript updatekernel:

vi /install/postscripts/updatekernel

Add the following lines to the file

1 2	#!/bin/bash rpm -Uivh data/kernel-*rpm

Change the permission on the file

chmod 755 /install/postscripts/updatekernel

Add the script to the postscripts table and run the install:

chdef -p -t group -o compute postscripts=updatekernel
rnetboot compute
