Configuration for Diskful Installation

1. Set script mlnxofed_ib_install as postbootscript

   chdef <node> -p postbootscripts=mlnxofed_ib_install
   

2. Specify dependence package [required for RHEL and SLES]

1. Copy the pkglist to the custom directory

   cp /opt/xcat/share/xcat/install/<ostype>/compute.<osver>.<arch>.pkglist \
      /install/custom/install/<ostype>/compute.<osver>.<arch>.pkglist
   

2. Edit your /install/custom/install/<ostype>/compute.<osver>.<arch>.pkglist and add one line:

   #INCLUDE:/opt/xcat/share/xcat/ib/netboot/<ostype>/ib.<osver>.<arch>.pkglist#
   

3. Make the related osimage use the customized pkglist

   chdef -t osimage -o <osver>-<arch>-install-compute  \
      pkglist=/install/custom/install/<ostype>/compute.<osver>.<arch>.pkglist
   

Take RHEL 6.4 on x86_64 for example

cp /opt/xcat/share/xcat/install/rh/compute.rhels6.x86_64.pkglist \
/install/custom/install/rh/compute.rhels6.x86_64.pkglist

Edit the /install/custom/install/rh/compute.rhels6.x86_64.pkglist and add below line #INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels6.x86_64.pkglist#

Then /install/custom/install/rh/compute.rhels6.x86_64.pkglist looks like below

#Please make sure there is a space between @ and group name
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels6.x86_64.pkglist#
ntp
nfs-utils
net-snmp
rsync
yp-tools
openssh-server
util-linux-ng

Then modify related osimage

chdef -t osimage -o rhels6.4-x86_64-install-compute  \
 pkglist=/install/custom/install/rh/compute.rhels6.x86_64.pkglist

3. Install node

   nodeset <node> osimage=<osver>-<arch>-install-compute
   rsetboot <node> net
   rpower <node> reset
