You can do the following:
By default, in a MSCS cluster, failover from the controlling node to a designated node occurs in alphabetical order according to the machine name of each node. To change the order in which failover will occur on the designated nodes, rename the machines in the order in which they should fail over.
VCS uses a priority list as the primary method for determining the failover target. To set the priority in VCS, highlight the Backup Exec group in the VCS Cluster Explorer and select Tools>System Manager. Modify the priority field to reflect the desired order.
If you have added a failover node, also add any locally attached storage devices that are to be used when failover occurs to the cluster device pool. This ensures that jobs can be run on the storage devices that are attached to the failover nodes.
If you remove some, but not all, nodes in a cluster, an uninstall of Backup Exec results in a password being requested for the virtual server and the services continuing to run. You must remove Backup Exec from all nodes on the cluster.
