\# ./installer -start sys1 sys2
  1. Make the configuration writable on the first subcluster.
    \# haconf -makerw
    1. Unfreeze the nodes in the first subcluster.
    \# hasys -unfreeze -persistent node01
    \# hasys -unfreeze -persistent node02
  2. Dump the configuration and make it read-only.
    \# haconf -dump -makero
    1. Bring the service groups online on node01 and node02.
    \# hagrp -online sg1 -sys node01
    \# hagrp -online sg1 -sys node02
    \# hagrp -online sg2 -sys node01
    \# hagrp -online sg2 -sys node02
    \# hagrp -online sg3 -sys node01
    \# hagrp -online sg4 -sys node02
