Adding software to a shared resource tree
Install additional software into an existing SRT only if it is required during a restore. Additional software may include an operating system patch or fileset that NetBackup client software requires. The software in an SRT is not installed on the restored system. It only brings the protected system to a state from which the original files can be restored. Therefore, you do not need to install the following: patches, maintenance levels, maintenance packs, service packs, fileset, or drivers into an SRT that are in a protected system.
Clustering software does not need to be installed into an SRT. After the local file systems are restored, the client rejoins the cluster.
