SUMMARY OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
Patch ID: 7.1.0.100
* 3897530 (3897531) Application agent type resource defaults to root user 
when running MonitorProgram irrespective of the user specified in 
the User attribute.


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following incidents:

Patch ID: 7.1.0.100

* 3897530 (Tracking ID: 3897531)

SYMPTOM:
Application agent type resource defaults to root user when running 
MonitorProgram even when non-root user is specified in the User attribute.

DESCRIPTION:
Application agent should execute MonitorProgram in the context 
of user specified in the User attribute of the Application agent type 
resource, but instead it defaults to root user even when non-root user is 
specified in the User attribute. 

Following is a sample configuration for Application agent type resource with 
'vcsuser' specified in the User attribute:

Application sampleapp (
        User = vcsuser
        MonitorProgram = "/sample/monitorapp"
        UseSUDash = 1
        StartProgram = "/sample/startapp"
        StopProgram = "/sample/stopapp"
        )

MonitorProgram for the resource should execute in the context of vcsuser, 
but instead it executes in the context of the root user.

RESOLUTION:
Application agent is modified to execute MonitorProgram in the 
context of non-root user specified in the User attribute of the Application 
agent type resource.

2. Change to the Veritas InfoScale 7.1 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:
--------------------------
Perform the following steps on all nodes in the Cluster Server (VCS) cluster:
1. Backup your configurations. 
2. Stop VCS on the cluster node.
3. Install the patch.
4. Restart VCS on the node.

Stopping VCS on the cluster node
--------------------------------
Perform the following steps:
1. Ensure that the "/opt/VRTSvcs/bin" directory is included in your PATH
   environment variable so that you can execute all the VCS commands. Refer
   to the Veritas InfoScale Installation Guide for more information.

2. Ensure that the VRTSvcsag package version for Linux is 7.1.
    # rpm -q VRTSvcsag
   The following output is displayed:
   For RHEL7:
    # VRTSvcsag-7.1.0.000-RHEL7.x86_64

3. Freeze all the service groups persistently.
    # haconf -makerw
    # hagrp -freeze [group] -persistent

4. Stop the cluster on all nodes. If the cluster is writable,
   close the configuration before stopping the cluster.
    # haconf -dump -makero

5. From any node, execute one of the following commands:
    # hastop -all
    or
    # hastop -all -force

6. Verify whether you have stopped the cluster on all nodes: 
    # hasys -state
   The following output must be displayed:
   VCS ERROR V-16-1-10600 Cannot connect to VCS engine

7. Ensure that you stop both had and hashadow processes on all nodes.
   
8. Stop the VCS CmdServer on all nodes:
    # CmdServer -stop


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:
   For RHEL7:
    # rpm -Uvh VRTSvcsag-7.1.0.100-RHEL7.x86_64.rpm
     
2. Verify whether the new patch has been installed:
    # rpm -q VRTSvcsag
   If the correct patch is installed, the following output is displayed:
   For RHEL7:
    # VRTSvcsag-7.1.0.100-RHEL7.x86_64

    
Restarting VCS on the cluster node
-----------------------------------

1. To start the cluster services on all cluster 
   nodes, enter the following command first on one node:
    # hastart

   On all the other nodes, execute the hastart command to start VCS after the 
   first node goes to LOCAL_BUILD or RUNNING state.

2. Make the VCS cluster writable:
     # haconf -makerw

3. Unfreeze all the groups:
     # hagrp -unfreeze [group] -persistent
     # haconf -dump -makero


REMOVING THE PATCH
------------------
If you uninstall the patch, the whole package is uninstalled 
from the system/node. To go back to a previously installed version 
of the package, you may need to reinstall the package.
Perform the following steps on all the VCS cluster nodes:

To uninstall the patch from a cluster node:
---------------------------------------------
1. Freeze all the service groups persistently:
    # haconf -makerw
    # hagrp -freeze [group] -persistent

2. Stop VCS on the node by following the steps provided in the  
   "Stopping VCS on the cluster node" section.

3. Uninstall the patch:
    # rpm -e VRTSvcsag

4. Verify that the patch has been uninstalled from the system:
    # rpm -qa | grep VRTSvcsag
   Ensure that the VRTSvcsag package is not displayed. This confirms 
   that the package has been uninstalled.

5. Install the VRTSvcsag 7.1 package from the installation media.

6. To start the cluster services on all cluster nodes, 
   enter the following command first on one node:
    # hastart

   On all the other nodes, execute the hastart command to start VCS after the 
   first node goes to LOCAL_BUILD or RUNNING state.

7. Unfreeze all the groups:
    # hagrp -unfreeze [group] -persistent
    # haconf -dump -makero
