information in an ASCII configuration file called main.cf, which is locatedin the path pointed by %VCS_HOME%conf/config on each node in thecluster. If this file is corrupted, the cluster configuration is also corrupted.Be very careful when handling this file. The VCS_HOME environmentvariable points to the directory where VCS is installed on the node.passwordaccessSpecify the generate value.managedservices(Optional). Specifies whether the Tivoli Storage Manager Client Acceptorservice (CAD) manages the scheduler, the Web client, or both. Theexamples in this appendix assume that the CAD manages both the Webclient and the scheduler for each cluster group. To specify that the CADmanages both the Web client and the scheduler, enter the following optionin the dsm.opt file for each cluster group:managedservices webclient scheduleerrorlognameSpecify a unique error log name.Note: This is not the same errorlog file that the client uses for otheroperations. Ideally, this file should be stored on a cluster resource, but atthe very least it should be stored in a location other than the clientdirectory.schedlognameSpecify a unique schedule log name.Note: This is not the same schedlog file that the client uses for otheroperations. Ideally, this file should be stored on a cluster resource, but atthe very least it should be stored in a location other than the clientdirectory.Related reference“Clusternode” on page 321“Domain” on page 346“Errorlogname” on page 363“Managedservices” on page 411“Nodename” on page 419“Passwordaccess” on page 425“Schedlogname” on page 452Step 3: Configure the scheduler serviceConfigure a Tivoli Storage Manager backup-archive scheduler service for eachcluster group using one of the following: (1) Tivoli Storage Manager schedulersetup wizard, by choosing This is a cluster node, or (2) Client ServiceConfiguration Utility, dsmcutil.Configure the scheduler service on each node in the cluster group. The schedulerservice must have the same name on each node and be available for failover(moved to the other nodes in the cluster).To install the Tivoli Storage Manager Scheduler Service for group-a fromworkstation node-1, ensure that node-1 currently owns group-a and issue thefollowing command:Chapter 2.
