INCIDENT FIXED IN THIS PATCH
----------------------------
1844884: [VCS][230-683-644]Gradual increase of memory consumption 
         of MultiNICB agent


SDR OF FIXED SYMANTEC INCIDENTS:
---------------------------------

Symantec Incident: 1844884

Symptom:
The MultiNICB agent memory consumption continuously increases gradually.
This can be observed by perioducally referring to ps -elf output for the
/opt/VRTSvcs/bin/MultiNICB/MultiNICBAgent process.

Defect Description:
This behavior is due to memory leak in the MultiNICB agent.

Resolution:
The hot fix remediates this issue by fixing the memory leak in the
MultiNICB agent.



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

1. Ensure that "/opt/VRTS/bin" directory is included in your PATH
   environment variable so you can execute all the VCS commands. Refer
   to Veritas Cluster Server Installation Guide for more information.

2. Verify that the version of VRTSvcs is 5.0MP2 or 5.0MP2RP1 for HP-UX 11i v2.

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 one node, execute the following command.

    # hastop -all

   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.
   Also, stop the VCS CmdServer on all nodes. 
   Determine the PID of the CmdServer and enter:

    # CmdServer -stop

5. On each node, extract the patch from its tar archive.
   Run the following commands:

    # cd <patch_location>
    # tar -xvf <Patch Tarball File>

6. Change directory to the patch/ directory inside the extracted
   location:

    # cd patches/

7. Install the patch using swinstall command:

    # swinstall -s `pwd` PVCO_03898

8. Verify that the patch is successfully installed.

    # swlist | grep PVCO_03898

   The output should resemble to following:

   PVCO_03898   1.0       VRTS 5.0 MP2 RP1 HF1 VRTSvcs/VRTSvcsag Command Patch

9. At this time, you can start the cluster services on all cluster nodes.
   First start VCS on one node:

    # hastart

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

10. Unfreeze all the groups.

     # haconf -makerw
     # hagrp -unfreeze <group> -persistent
     # haconf -dump -makero


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

1. Make sure that VCS is not running in the cluster.
    # hastop -all

    or

    # hastop -all -force

2. Remove the patch using swremove command

    # swremove PVCO_03898

3. Verify that the patch is removed from each system.
   Type:

    # swlist | grep PVCO_03898

   If the patch gets removed successfully, the command will not display any
   output.
