I.  INTRODUCTION
================
There is a problem with the NetBackup upgrade process when upgrading (from
NetBackup 5.x to NetBackup 6.0) in a NetBackup cluster environment that
results in the EMM database being created in /usr/openv, rather than on the
shared disk. To determine if this issue affects you, refer to
TechNote 293034, found below in the Related Documents section.

NOTE: If you have decided to use a Remote EMM server (that is to say, an
     EMM server that is not the master server) this package does not apply.
     You should, however, refer to the Veritas NetBackup 6.0 Upgrade Guide
     for additional, required steps.  To view the NetBackup 6.0 Upgrade Guide,
     refer to the following TechNote on the NetBackup Upgrade Portal, a part
     of the Symantec NetBackup Support Web site.  

       http://support.veritas.com/docs/285590

If you have determined that this issue affects you, and you have not
performed an upgrade yet, you can prevent the problem by running a modified
upgrade procedure to install this patch described in the INSTALLATION
INSTRUCTIONS section below.  

If, however, you have already performed the upgrade and have run the
"nbpushdata -add" command, or the system has run for any length of time on
the first (initially active) node, contact Symantec Technical Services for
further assistance and do not install this package.  



=========================
II. DOWNLOAD INSTRUCTIONS
=========================
1) Download the NB_6.0I1_<6 digit number>.tar file into the  
  /tmp directory, on each node of the cluster that you are upgrading.

  - where <6 digit number> is an internal tracking identifier

2) Extract the NB_6.0I1_<6 digit number>.tar files.
  tar xvf NB_6.0I1_<6 digit number>.tar to each node of the cluster
  that you are upgrading.

       NB_6.0I1 will create the files:
       VrtsNB_6.0I1.README
       cluster_upgrade


 
==============================
III. INSTALLATION INSTRUCTIONS
==============================
Before installing this Independent patch, please review the following items:
 - Symantec recommends that you perform catalog backups before and after you
   apply this patch.

 - If you are planning to install this Independent patch as a part of an
   upgrade from a 5.x release then it is important that you understand that
   the existing NetBackup databases must be in a consistent state prior to
   beginning the upgrade. Information and tools to assist you in determining
   the current state of your database, as well as instructions to help you
   address any inconsistencies that you might discover can be viewed on the
   NetBackup Upgrade Portal, a part of the Symantec NetBackup Support Web site.  

       http://www.symantec.com/enterprise/support/overview.jsp?pid=15143

 - If you are upgrading from 5.x to 6.0, you must install this Independent
   patch at a specific time during the upgrade process or the upgrade may fail.  
   This is described in detail in the following Modified upgrade procedure.  


Modified upgrade procedure
--------------------------
Perform the following to upgrade to NetBackup 6.0 from NetBackup 5.x.

1. Ensure that you have the 6.0I1 package that you downloaded from the NetBackup
  Support Web site extracted to each node in the cluster. This package consists
  of a modified version of the following script:

     /usr/openv/netbackup/bin/cluster/cluster_upgrade.  

2. Begin your upgrade on the first inactive node in accordance with the
  directions documented in the NetBackup Installation Guide and the High
  Availability (HA) Guide, with the following additional step:

  -  During the upgrade, when you see the following prompt, DO NOT respond to
     the question.

     "Do you want to continue the installation with the current active
      NetBackup license key"  

3. Open a second window on the node that is being upgraded and replace the
  cluster_upgrade script with the 6.0I1 version of the file that is included
  with this package, for example:

  # mv /usr/openv/netbackup/bin/cluster/cluster_upgrade /usr/openv/netbackup/
    bin/cluster/cluster_upgrade.SAVE

  # cp /tmp/cluster_upgrade /usr/openv/netbackup/bin/cluster/cluster_upgrade

4. Ensure the cluster_upgrade script has execute permissions set, for example:

  # chmod 555 /usr/openv/netbackup/bin/cluster/cluster_upgrade

5. Return to the first window and respond to the license key prompt and  
  proceed with the upgrade process of the node as normal.

6. Repeat Steps 2 through 5 for any remaining inactive nodes and then perform
  the steps one more time for the active node.  

  NOTE: It is important that the active node be done last.  

7. After you have finished the upgrade on the active node, you can perform the
  following to verify that the EMM database has been created in the correct
  location.
  a.  View the contents of /usr/openv/netbackup/bp.conf  

  b.  If the VXDBMS_NB_DATA parameter exists in the bp.conf file, then you
      are on the EMM server.  

  c.  If VXDBMS_NB_DATA is set, then your upgrade has been successful if
      this parameter points to a shared disk data directory similar to the
      following:

      VXDBMS_NB_DATA = <shared_disk_mount>/db/data

      NOTE: If the VXDBMS_NB_DATA parameter in bp.conf indicates a path other
            than a shared path (for example, /usr/openv/db/data), then the
            upgrade was performed incorrectly and you should contact Symantec
            Technical Services.

8. Continue with the remainder of the upgrade process as documented in the
  NetBackup Installation Guide and the High Availability Guide.
