Using SystemImager with xCAT

1. Install/Configure xCAT (see xCAT Mini HowTo)

2. Install/Configure SystemImager

3. Create build image from golden client:

      # getimage --golden-client myprecious --image myimage ...
      

4. Create a blank template file for the image name

      # touch /opt/xcat/install/systemimager/x86/base/myimage.tmpl
      

   Note: this file is only used to prevent nodeset from complaining.

5. Update nodetype.tab

         node001 systemimager,x86,myimage
         node002 systemimager,x86,myimage
      

6. Set up post-imaging node boot: There are 2 options here:
   • Make sure SystemImager's netbootmond is running (with NET_BOOT_DEFAULT = local in /etc/systemimager/systemimager.conf).
   • Create a post-install script in /var/lib/systemimager/scripts/post-install (based on /opt/xcat/install/postscripts/updateflag) to notify xcatd when imaging is complete.
   The 1st route is easier, the 2nd route is cleaner.

7. To image some nodes, just use your normal xCAT commands

      # rinstall node001-node002
