Preparation

Prepare the Cumulus Linux files on the xCAT Management Node.

1. Obtain a valid Cumulus Linux License and download the Cumulus Linux OS installer.

2. Copy the above files into a location under the xCAT /install directory.

   # Create a directory to hold the cumulus linux files
   mkdir -p /install/custom/sw_os/cumulus/
   
   # copy the license file
   cp licensefile.txt /install/custom/sw_os/cumulus/
   
   # copy the installer
   cp cumulus-linux-3.1.0-bcm-armel.bin /install/custom/sw_os/cumulus/
   

Cumulus osimage

xCAT can able to create a cumulus osimage definition via copycds command. copycds will copy cumulus installer to a destination directory, and create several relevant osimage definitions. cumulus<release>-<arch> is the default osimage name.

#run copycds command
# copycds cumulus-linux-3.5.2-bcm-armel.bin

The pkgdir attribute will contain full path of cumulus installer as /install/cumulus<release>/<arch>/<installer>.

# lsdef -t osimage cumulus3.5.2-armel
Object name: cumulus3.5.2-armel
