First, halt any packages running on the node you want to disable. Either restart those packages on other node(s), or leave them halted, whichever is more appropriate to you.
Then, run "cmhaltnode" on the node you want to disable.
Then edit the /etc/rc.config.d/cmcluster file: it contains a variable named AUTOSTART_CMCLD that determines whether or not the node will attempt to rejoin the cluster at boot time. Change it to AUTOSTART_CMCLD=0 for the duration of the upgrade.
