To prevent VCS from starting after rebooting, do the following on the removed node :

1. Unconfigure and unload GAB
      
      /sbin/gabconfig  -u
      modunload -i `modinfo | grep gab | awk '{print $1}`

2. Unconfigure and unload LLT

      /sbin/lltconfig  -U      

      modunload -i `modinfo | grep llt | awk '{print $1}`

3. Prevent LLT, GAB and VCS from starting up in the future

      mv  /etc/rc2.d/S70llt   /etc/rc2.d/s70llt
      mv  /etc/rc2.d/S92gab   /etc/rc2.d/s92gab
      mv  /etc/rc3.d/S99vcs   /etc/rc3.d/s99vcs

4. If  it ** is not **  desired to be running VCS on this particular node again,  all the VCS related packages and files can now be removed.

      pkgrm VRTSperl
      pkgrm VRTSvcs
      pkgrm VRTSgab
      pkgrm VRTSllt
      
      rm /etc/llttab
      rm /etc/gabtab
