1.  Copy the point patch to a directory on your system:

	# cp <patch>.tar.gz .

2.  Unzip the compressed patch files that you want to install & untar:

	# gunzip <patch>.tar.gz
	# tar -xvf <patch.tar>

3.  Verify that /opt/VRTS/bin is in your PATH so you can execute all the 
    product commands. Refer to the VCS Installation Guide for more 
    information.

4.  Verify that the version of VRTSvcs is 5.0 MP3.
 
    On each system, type:
	# lslpp -l VRTSvcs.rte

    Output resembles:

5. Stop the cluster on all nodes. From one node, execute the
   following command.

	# hastop -all -force

   Verify that the cluster is stopped on all nodes 
   by running the ha command.

	# hasys -state

   On all nodes, stop the VCS CmdServer. 
   Determine the PID of the CmdServer and enter:
        # kill -9 <PID>

6. On each node of the cluster, commit filesets that are in the applied 
   state. This step allows you to remove this patch and revert to the 
   previous one, if necessary.
          
    a. Find out if the filesets are in applied states. On each system,
       type:
 
	# lslpp -L | grep VRTS
	
       The output for a single fileset should be similar to:
       
	VRTSvcs.rte   5.0.3.0  A   F    Veritas Cluster Server
       
       The 'A' in the output indicates that the file is applied, but not 
       committed.	    

    b. Commit any filesets that are in the applied state. On each system,
       type:

	# installp -c <fileset>
   	
       For example, for fileset VRTSvcs.rte:
   	
	# installp -c VRTSvcs.rte

    c. Verify that the filesets have changed state. On each system, type:

	# lslpp -L | grep VRTS

       The output should be similar to:

	VRTSvcs.rte   5.0.3.0  C   F    Veritas Cluster Server
	
       The 'C' in the output indicates that the file is committed.

8. Change directory to the patch location.

     # cd <patch_location>   

9. Install the patch using the installp command:

     # installp -aXd VRTSvcs.rte.bff VRTSvcs 

10. After installation is complete, verify that the patch is installed on
    each system. For example, type:   
    
      # lslpp -L VRTSvcs.rte
        
    The following information is displayed after successful patch installation:
   
      VRTSvcs.rte     5.0.3.1    A     F    Veritas Cluster Server


11. At this time, you can start cluster on all cluster nodes.
    On one node, please verify if VCS configuration is valid.

	# hacf -verify config

    If the configuration is valid, start VCS.

	# hastart

    On all other nodes, start VCS by issuing hastart once the
    first nodes goes to LOCAL_BUILD or RUNNING state.

REMOVING THE VCS PATCH 
----------------------
To remove the patch from a running VCS cluster:

1.  Perform step 5 from INSTALLING THE PATCH procedure.

2.  Remove the patch using the installp command:

      # installp -r VRTSvcs.rte
         
4.  Verify that the patch has been removed from each system. 
    For example, type:   
    
      # lslpp -L VRTSvcs.rte
        
    The following information is displayed after successful patch removal:
   
	VRTSvcs.rte   5.0.3.0  C   F    Veritas Cluster Server

5. Restart the cluster by following step 11 from INSTALLING THE PATCH
   procedure.
