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

Patch ID: VRTSdbac-6.2.0.100-RHEL7

* 3861194 (Tracking ID: 3861191)

SYMPTOM:
VRTSdbac patch version does not work with RHEL7.2 (3.10.0-319.el7.x86_64 
kernel) and is unable to load the vcsmm module on RHEL7.2 .

DESCRIPTION:
Installation of VRTSdbac patch version 6.2.0 fails on RHEL7.2 as 
the VCSMM module is not available on RHEL7.2 kernel 3.10.0-319.el7.x86_64. 
The system log file logs the following messages:
Starting VCSMM: 
ERROR: No appropriate modules found.
Error in loading module "vcsmm". See documentation.
Error : VCSMM driver could not be loaded.
Error : VCSMM could not be started.
Error : VCSMM could not be started.

RESOLUTION:
The VRTSdbac package is re-compiled with RHEL7.2 kernel in the build 
environment to mitigate the failure.

Patch ID: VRTSllt-6.2.1.200-RHEL7

* 3861312 (Tracking ID: 3861308)

SYMPTOM:
Veritas Cluster Server (VCS) does not support Red Hat Enterprise Linux 7 Update
2 (RHEL7.2).

DESCRIPTION:

Update 1 (RHEL7.1).

RESOLUTION:
VCS support for Red Hat Enterprise Linux 7 Update 2 (RHEL7.2) is now introduced.



INSTALLING THE PATCH
--------------------
Run the Installer script to automatically install the patch:
-----------------------------------------------------------
To install the patch perform the following steps on at least one node in the cluster:
1. Copy the patch sfha-rhel7.2_x86_64-Patch-6.2.1.100.tar.gz to /tmp
2. Untar sfha-rhel7.2_x86_64-Patch-6.2.1.100.tar.gz to /tmp/hf
    # mkdir /tmp/hf
    # cd /tmp/hf
    # gunzip /tmp/sfha-rhel7.2_x86_64-Patch-6.2.1.100.tar.gz
    # tar xf /tmp/sfha-rhel7.2_x86_64-Patch-6.2.1.100.tar
3. Install the hotfix
    # pwd /tmp/hf
    # ./installSFHA621P1 [<host1> <host2>...]

You can also install this patch together with 6.2 GA release and 6.2.1 Patch release 
using Install Bundles
1. Download Storage Foundation and High Availability Solutions 6.2
2. Extract the tar ball into the /tmp/sfha6.2/ directory
3. Download SFHA Solutions 6.2.1 from https://sort.veritas.com/patches
4. Extract it to the /tmp/sfha6.2.1 directory
5. Change to the /tmp/sfha6.2.1 directory by entering:
    # cd /tmp/sfha6.2.1
6. Invoke the installmr script with -base_path and -patch_path option where the -base_path 
should point to the 62 image directory, while -patch_path to the 6.2.1.100 directory.   
    # ./installmr -base_path [<62 path>] -patch_path [<patch path>] [<host1> <host2>...]

Install the patch manually:
--------------------------
Perform the following steps on the node on which this patch is being applied:
1. Take backup of your configurations
2. Stop VCS
3. Install the patch
4. Restart VCS on the node

Stopping VCS on the cluster node
--------------------------------

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 Veritas Cluster Server Installation Guide for more information.

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

3. If the cluster is writable, you may close the configuration before stopping the cluster. 
    Stop the cluster on this node:
        # haconf -dump -makero

   stop VCS and vcsmm:
        # hastop -local
        # /etc/init.d/vcsmm stop
    
   Verify that the cluster is stopped by running the ha command:
    # hasys -state

   make sure that both had and hashadow processes are stopped. Also, stop the VCS CmdServer:
    # CmdServer -stop

4. Stop the cluster services in order:
    - For AMF:
    # /etc/init.d/amf stop
    - For VxFEN:
    # /etc/init.d/vxfen stop
    - For GAB:
    # /etc/init.d/gab stop
    - For LLT
    # /etc/init.d/llt stop
    
Note: Stop any other services depending on GAB

Installing the Patch
--------------------

1. Un-compress the downloaded patch from Symantec and change the directory to the uncompressed patch location.
   Install the patch using the following command:

    - For LLT:
    # rpm -Uvh VRTSllt-6.2.1.200-RHEL7.x86_64.rpm
    - For RAC:
    # rpm -Uvh VRTSdbac-6.2.0.100-RHEL7.x86_64.rpm 

2. Run the following command to verify if the new patch has been installed:

    - For LLT:
        # rpm -q VRTSllt
    - For RAC:
        # rpm -q VRTSdbac
            
   If the proper patch is installed, the following output is displayed:

        - For LLT:
    VRTSllt-6.2.1.200-RHEL7.x86_64.rpm
        - For RAC:
    VRTSdbac-6.2.0.100-RHEL7.x86_64.rpm
                            
Re-starting the cluster services:
--------------------------------

1. To start the cluster services in order run the following command:
        - For LLT:
        # /etc/init.d/llt start
        - For RAC:
        # /etc/init.d/vcsmm start
        
2. Make VCS cluster writable:
         # haconf -makerw

3. Unfreeze all the groups:
         # 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 the node where the patch is being uninstalled:

To remove 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 running the following command:
    - Follow the stop sequence as mentioned in the PATCH INSTALLATION section.

3. Remove the patch by using the following command:
        - For LLT:
        # rpm -e VRTSllt
        - For RAC:
        # rpm -e VRTSdbac
    
4. Verify that the patch has been removed from the system:
        - For LLT:
        # rpm -qa|grep VRTSllt
        - For RAC:
        # rpm -qa|grep VRTSdbac
            
   Ensure that the package is not be displayed. This confirms that the package is removed.

5. Install the relevant package from the VCS base media. 
    Also refer to SORT for any applicable patches.

6. To start the cluster service, run the following command first on one node:
    - Follow the start sequence as mentioned in the PATCH INSTALLATION section.

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