Using Veritas Operations Manager, you can manage the high availability application clusters based on Symantec Cluster Server. The Management Server console helps you perform all the VCS-related high availability and disaster recovery operations such as setting up global cluster (GCO), or bringing a service group or resource online.
You must note the following when you perform the high availability (HA) and disaster recovery (DR) operations using Veritas Operations Manager:
To perform DR operations such as remote online, remote offline, and switch, the remote cluster need not be managed by the same Management Server as the local cluster. However, at least one cluster in the global cluster option (GCO) setup needs to be managed by Management Server. To use Veritas Operations Manager for optimal management of clusters in an existing GCO setup, it is recommended that you include the clusters within a single Management Server domain.
You are prompted to open a closed configuration to perform an operation that requires configuration changes. If you choose to open the configuration automatically, Veritas Operations Manager provides an option to close the configuration after the operation is completed.
When an operation that involves configuration changes is performed, Veritas Operations Manager automatically dumps the configuration at the end of the operation.
For performing batch operations, you must have the appropriate privileges on all the objects that you have selected. If you do not have appropriate privileges on any of the selected objects, the entire operation does not succeed. In such cases, you need to deselect the objects where you do not have the privileges, and launch the wizard again to perform the operation.
