Upgrading

VCS 4.1 requires the HP-UX 11iv2 operating system. You must uninstall previous versions of VCS before performing the upgrade.

All custom agents must have their types defined in files named *.cf, located in /etc/VRTSvcs/conf/config. All files that the custom agent needs must be located in /opt/VRTSvcs/bin/AgentName directory.

1. Log on as root user on a node where VCS is running with the old configuration.
2. Backup all system configuration files, triggers, and custom agents (main.cf and custom agent types files) in a safe location before upgrading. For example:
   # cp /etc/VRTSvcs/conf/config/main.cf
   /path/to/stored/config/file/main.cf
3. Uninstall previous versions of VCS. Perform the uninstallation according to the Installation Guide for the version of VCS that you currently use.
4. Perform the operating system upgrade to HP-UX 11iv2 according to the appropriate HP-UX operating system documentation.

5. Perform the VCS installation to version 4.1 and restore the VCS configuration information.

   At the following prompt, do not proceed:

   
   Do you want to start VCS processes now ? (Y/n): 

   Stop and switch to another window. Do not close the window from where you ran the installer. See VCS Installation Utility.

6. If there are any binary custom agents, they will need a recompile. See VERITAS Cluster Server Agent Developer's Guide (vcs_adg.pdf), for more information.
7. Save the main.cf generated by the installer program.
   # cp /etc/VRTSvcs/conf/config/main.cf
   /etc/VRTSvcs/conf/config/main.cf.generated.for.4.1
8. Restore the following files, agents, and triggers:
   1. Restore the saved main.cf file to the /etc/VRTSvcs/conf/config directory.
   
   # cp /path/to/stored/config/file/main.cf
   /etc/VRTSvcs/conf/config/
   2. Restore the saved custom agent config files to the /etc/VRTSvcs/conf/config directory
   
   # cp /path/to/stored/custom/agents/files/*.cf
   /etc/VRTSvcs/conf/config/
   3. Restore all custom triggers to triggers directory.
   
      # cp /path/to/stored/triggers/* /opt/VRTSvcs/bin/triggers/  
   # cp /path/to/stored/internal_triggers/*
   /opt/VRTSvcs/bin/internal_triggers/
9. Remove the definition of the ClusterServiceGroup if it exists in the main.cf.
10. Copy the definition of the ClusterServiceGroup, with all the resources in that group, from the main.cf.generated.for.4.1 and paste it into /etc/VRTSvcs/conf/config/main.cf.
11. Refer to enterprise and custom agent's documentation for the upgrade procedure. Complete the upgrades for these agents before proceeding.
12. Verify that the configuration. Run the hacf -verify config command to check for errors.
13. Return to the window where you ran the installer in step 5.
14. Answer Y when prompted to start VCS.
