2. Change to the Veritas InfoScale 7.2 directory and invoke the installer script
   with -patch_path option where -patch_path should point to the patch directory
    # ./installer -patch_path [<path to this patch>] [<host1> <host2>...]

Install the patch manually:
--------------------------
The following steps should be run on all nodes in the VCS cluster:
1. Stopping VCS on the cluster node.
2. Installing the patch.
3. Restarting VCS on the node.
Stopping VCS on the cluster node
--------------------------------
To stop VCS on the cluster node:
1. Ensure that the "/opt/VRTS/bin" directory is included in your PATH
   environment variable so that you can execute all the VCS commands.
   For more information, refer to the Veritas Cluster Server
   Installation Guide.
2. Verify that the version of VRTSvcs is 7.2 for Linux.
3. Freeze all the service groups persistently.
    # haconf -makerw
    # hagrp -freeze [group] -persistent
    # haconf -dump -makero
4. Stop the cluster on all nodes. If the cluster is writable, you may
   close the configuration before stopping the cluster.
    # haconf -dump -makero
   From any node, execute the following command.
    # hastop -all
    or
    # hastop -all -force
   Verify that the cluster is stopped on all nodes
   by running the 'ha' command.
    # hasys -state
   On all nodes, make sure that both had and hashadow processes are
   stopped.
5. Log in as the super user into the system where the patch is to be
   installed.
6. Run the preceding steps on all nodes in the VCS cluster.
Installing the Patch
--------------------
Perform the following steps:
1. Un-compress the downloaded patch from Veritas.
   Change the directory to the uncompressed patch location.
   Install the VRTSvcsag patch using the following command:
# rpm -Uvh VRTSvcsag-7.2.0.100-RHEL6.x86_64.rpm
2. Run the following command to verify if the new patch has been installed:
    # rpm -q VRTSvcsag
   If the proper patch is installed, the following output is displayed:
   VRTSvcsag-7.2.0.100-RHEL6.x86_64
Re-starting VCS on the cluster node
-----------------------------------
1. To start the cluster services on all cluster
   nodes. Execute the following command first on one node:
    # hastart
   On all the other nodes, start VCS by executing the hastart command after the
   first node goes to LOCAL_BUILD or RUNNING state.
2. Unfreeze all the groups.
     # haconf -makerw
     # hagrp -unfreeze [group] -persistent
     # haconf -dump -makero


REMOVING THE PATCH
------------------
Removal of the patch will result in removing the whole package from the system/node. To go back to a previous installed version of the package, you may need to re-install the package.
Run the following steps on all the VCS cluster nodes:
To remove the patch from a cluster node:
---------------------------------------------
1. Stop VCS on the node by following the steps provided in the section
   "Stopping VCS on the cluster node".
2. Remove the patch by using the following command:
    # rpm -e --nodeps VRTSvcsag
3. Verify that the patch has been removed from the system:
    # rpm -qa | grep VRTSvcsag
   Ensure that the VRTSvcsag package is not be displayed. This confirms
   that the package is removed.
4. Install the VRTSvcsag package from the VCS 7.2 Installer CD
5. To start the cluster services on all cluster
   nodes, execute the following command first on one node:
    # hastart
   On all the other nodes, start VCS by executing hastart after the
   first node goes to LOCAL_BUILD or RUNNING state.


SPECIAL INSTRUCTIONS
--------------------
Install the patch and run the following commands sequentially:
# haconf -makerw
# haattr -add DiskGroup DGOptions
# hatype -modify DiskGroup ArgList -add DGOptions
Run the following command for every zone resource:
# hares -modify <diskgroup_resource>  DGOptions <DGOptions> 
Dump the configuration:
# haconf -dump -makero
