Upgrading the Agent

This section describes steps to upgrade from the VCS enterprise agent 3.5 for Sybase in a VCS cluster.

1. Save the VCS configuration and stop the VCS engine.
   # haconf -dump -makero
   # hastop -all -force
2. Back up the configuration file, main.cf to a location on the cluster node.
3. Follow step a through step c on all systems that have the Sybase agent installed.
   1. Remove the Sybase agent
   
      # swremove VRTSvcssy
   2. Delete the file /etc/VRTSvcs/conf/config/SybaseTypes.cf.
   3. Install the VCS enterprise agent 4.1 for Sybase. See Installing the Agent.
4. Copy the file SybaseTypes.cf from the /etc/VRTSvcs/conf/ directory to /etc/VRTSvcs/conf/config directory.
5. Copy the main.cf from the backed up location to /etc/VRTSvcs/conf/config.
6. Edit the main.cf located under /etc/VRTSvcs/conf/config.
   1. If you configured the Monscript attribute for the earlier version of the agent, replace Monscript with MonScript.
   2. Remove the Monscript attribute for the SybaseBk resource type.
   3. Replace the password specified for the SApswd attribute (of Sybase and SybaseBk resources) and UPword attribute (of Sybase resource) with encrypted passwords. See Encrypting Passwords for instructions on encrypting passwords.
   4. Save the main.cf
7. Verify the configuration.
   # cd /etc/VRTSvcs/conf/config
   # hacf -verify.
8. Start VCS on the local node.
9. Start VCS on other nodes.
