Installation and User's Guide

The new scheduler service is now associated with the cluster group. If the group ismoved (failed) to the other nodes in the cluster, the service should correctly failover between the cluster nodes and notify both cluster nodes of automaticpassword changes.Note: If you manually change the Tivoli Storage Manager password, you muststop the scheduler service, regenerate the password, and restart the schedulerservice. The password can be generated by running the command:dsmc query session -optfile="q:\tsm\dsm.opt"Important: The generic service resource should remain online during anypassword changes. Password corruption occurs if the generic service resource isoffline while the password is changed.VCS:VCS provides a separate utility to create or modify your existing configuration.This utility is called the VCS Configuration Editor. By default, this utility isinstalled when VCS Cluster Manager is installed. You can also manually edit theVCS configuration file main.cf file; refer to the appropriate VCS documentation formore information.To add a Generic Service resource to each cluster group managed by thebackup-archive client, use the VCS Configuration Editor, as follows:1. Open the VCS Configuration Editor. You are prompted with the Build a newconfiguration or modify existing configuration window which provides thefollowing options: New Config - If you select this option you are prompted forthe path for the types.cf file, and Open Existing Config - If you select thisoption, the configuration window opens.

In the Registry Replication dialog box, add the registry key corresponding tothe Tivoli Storage Manager node name and server name. The format for thiskey is: HKEY_LOCAL_MACHINE\SOFTWARE\IBM\ADSM\CurrentVersion\Nodes\\, where nodename is the name of yourTivoli Storage Manager node, and server_instance_name is the name of the TivoliStorage Manager server that the node connects to. For example, if the nodename is mscs-cluster-group-a and the Tivoli Storage Manager server name istsmsv1, enter the following registry key in the Registry Replication dialog box:HKEY_LOCAL_MACHINE\SOFTWARE\IBM\ADSM\CurrentVersion\Nodes\mscs-cluster-group-a\tsmsv1. This entry matches an existing key in theWindows Registry.7. Select the ServiceName attribute and enter the name of scheduler or CADservice that you want to make High-Availability.8.
