Special installation guidelines for Linux clustered environments

Use the following guidelines when you install NetBackup in clustered systems:

Ensure that each node in the NetBackup cluster can run the ssh command. The root user must be able to perform a remote login to each node in the cluster without entering a password. This remote login is necessary for installation and configuration of the NetBackup server and any NetBackup options. After installation and configuration are completed, it is no longer required.
You must install, configure, and start the cluster framework before you install NetBackup. For additional installation prerequisites and installation notes, see the NetBackup Clustered Primary Server Administrator's Guide.
You must have defined a virtual name using DNS, NIS, or /etc/hosts. The IP address is defined at the same time. (The virtual name is a label for the IP address.) Use this virtual name and IP address only for the NetBackup resource.
