    To create a 2 node cluster, you should run vcsinstall -configure on one of the nodes and have passwordless ssh between the 2 servers (or rsh and use -rsh flag on vcsinstall).  Have you tried this and if so what error did you get. 

    Your problem maybe you have not setup heartbeats in VMWare - you should create at least one, ideally 2 private (Host-only) networks in VMware for the heartbeats.

    If vcsinstall in failing, you can install manually instead - on both nodes:

     

    Create /etc/llthosts containing:

    0 nodename1 
    1 nodename2

    /etc/llttab containing:

     set-node /etc/VRTSvcs/conf/sysname
    set-cluster ClusterId
    link link1 NicDevice1 - ether - -
    link link2 NicDevice2 - ether - -
     /etc/VRTSvcs/conf/sysname containing:
     nodename
     
    /etc/gabtab containing:
     /sbin/gabconfig -c -n 2
     
    1. Check contents of /etc/sysconfig/vcs for line that says ONENODE= to make sure this says no
    2. You may need to copy types.cf file from /etc/VRTSvcs/conf to /etc/VRTSvcs/conf/config
    3. Create a main.cf file on one of the nodes in /etc/VRTSvcs/conf to /etc/VRTSvcs/conf/config as follows:
      include "types.cf"
      cluster cluster_name (
      )
      system nodename1 ()
      system nodename2 ()
       
    4. Start LLT - I think path is - /etc/rc2.d/S70llt start (both nodes)
    5. Start GAB - I think path is - /etc/rc2.d/S92gab start
    6. Start VCS on the node you created main.cf - /opt/VRTSvcs/bin/hastart
    7. Start VCS on the other node /opt/VRTSvcs/bin/hastart
    8. Run  /opt/VRTSvcs/bin/hauser -add admin -priv Administrator
