About support for HP-UX Itanium vPars SRP containers
Hewlett-Packard Enterprise (HPE) introduced a new type of container for HP-UX Virtual Partitions (vPars)-enabled servers called Secure Resource Partitions (SRPs). As part of the security changes introduced by SRPs, native HP-UX install tools such as swinstall and swremove are run from being executed within the SRP environment. The swinstall and swremove tools can only be called from the global host running vPars, which then pushes the native packages to the SRP containers.
NetBackup only supports installing into the global view. NetBackup installation fails if you try to install into an HPE Itanium SRP container (private file system, shared file system, or workload).
