Install/Uninstall Instructions
-------------------------------

GETTING STARTED
---------------

This patch is for VCS 5.0MP1EXT on AIX systems. The patch supports the AIX scalable volume group
through the VCS LVMVG storage agent. If you are running a VCS version lower than VCS 5.0MP1EXT, 
then before applying this patch, you must upgrade to VCS 5.0MP1EXT. 


INSTALLING THE VCS PATCH
------------------------

Run the following commands from any node in the cluster.


1.  Make the VCS configuration writable:
      # haconf -makerw

2.  Freeze all service groups:
      # hagrp -freeze <service_group> -persistent

3.  Verify if the service groups are frozen:
      # hastatus -sum

4.  Save this configuration change to the main.cf file with the groups frozen.
    On any system, execute the following command:
    	# haconf -dump -makero

5.  Stop VCS. On any system, execute the following command:
      # hastop -all -force

6.  Ensure that VCS shuts down:
      # ps -ef | grep had

7.  To install the patches, execute following command:
	# installp -a -d VRTSvcsag.rte.bff VRTSvcsag.rte

8. To verify if the patches are successfully installed, execute the following
   command:
	  # lslpp -l | grep VRTSvcsag.rte
   The following output must appear:
	  VRTSvcsag.rte            5.0.1.101  APPLIED    Veritas Cluster Server

9. Restart VCS. On each system in the cluster, execute the following command:
      # hastart      

10. Verify if all the resources are probed:
      # hastatus -summary

11. Make the configuration writable, and unfreeze all service groups: 
      # haconf -makerw
      # hagrp -unfreeze <service_group> -persistent

12. Save the changes to the configuration file (main.cf):
      # haconf -dump -makero         


REMOVING THE PATCH
-------------------

To remove the patch from a running VCS cluster:

1.  Make the VCS configuration writable:
      # haconf -makerw

2.  Freeze the service groups. On any system, execute the following command:
      # hagrp -freeze <service_group> -persistent
      
3.  Save the configuration file (main.cf) with the groups frozen. On any system, 
    execute the following command:
      # haconf -dump -makero
      
4.  Stop VCS. On any system, execute the following command:
      # hastop -all -force

5.  Uninstall the patch:
      # installp -r VRTSvcsag.rte
   
6.  Restart VCS. On each system in the cluster, execute the following command:
      # hastart         
 
7. Verify if all resources are probed:
      # hastatus -summary

8. To make the configuration writable and unfreeze all service groups, on any 
   system, execute the following command:
      # haconf -makerw
      # hagrp -unfreeze <service_group> -persistent

9. Save the changes to the configuration file (main.cf):
      # haconf -dump -makero
