We do not recommend installing Backup Exec on the same disk that the cluster quorum is installed on. If you have to specify a new drive letter for the quorum disk during a recovery process, Backup Exec will not recognize the new drive and will not run.
By default, 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.
The Remote Agent is automatically installed on all the nodes in the cluster. If this installation of Backup Exec will be used to back up remote servers outside the cluster, install the Remote Agent on those remote servers as well.

When the Cluster Configuration Wizard completes, create a device pool that contains all the locally attached storage devices on each node to be used when failover occurs. This ensures that jobs can be run on the storage devices that are attached to the failover nodes.
