Installation Notes

Note the following considerations before you install VERITAS NetBackup and Sun Cluster HA for NetBackup. Figure 1 illustrates the configuration limitations.

• VERITAS NetBackup is a single-instance data service. You cannot run more than one instance of VERITAS NetBackup per cluster.

• You must install NetBackup master servers in a cluster.

• NetBackup clients can exist inside a cluster or outside a cluster.

• You cannot include NetBackup media servers and their backup devices (tape libraries, optical readers, and so on) in any cluster.

• The shared disk that is associated with the NetBackup master server should be large enough to accommodate the NetBackup administrative files and logs that accumulate over time. The size of the administrative files and logs depends upon the amount of backup activity that is required for your configuration.

• If the VERITAS NetBackup client is a cluster, only one logical host can be configured as the client because there is only one bp.conf file.

• If the NetBackup client is a cluster and if one of the logical hosts on the cluster is configured as the NetBackup client, NetBackup cannot back up the physical hosts.

• On the cluster that runs the master server, the master server is the only logical host that can be backed up.

• Backup media cannot be attached to the master server, so one or more media servers are required.

• In a Sun Cluster environment, robotic control is supported only on media servers and not on the NetBackup master server that runs on Sun Cluster.
