This capability is termed shared library support.Robot types that support shared library are ACS, TL8, TLD, TLH, TLM.■Partitioned librariesSome robot vendors also let you partition libraries. One partitioned view of therobotic library includes one set of drives, while the other view has a different setof drives in the library. Partitions let two robotic control daemons on differentcontrol hosts manage the robotic library — possibly each for a differentNetBackup master and media server environment.These capabilities are not related to the Shared Storage Option and should not beconfused with the Shared Storage Option.61Additional configurationAbout the Shared Storage Option
Shared Storage Option terms and conceptsTable 2-7describes the terms and the concepts relevant to understanding theShared Storage Option.Table 2-7Shared Storage Option terms and conceptsDefinitionTermThe NetBackup Shared Storage Option is not the same as theVeritas Backup Exec Shared Storage Option. The Backup ExecSSO does not include support for UNIX servers and uses a differentmethod for drive arbitration.Backup Exec SharedStorage OptionA NetBackup SAN media server backs up its own data to shareddrives. It cannot back up data on other NetBackup hosts or clients.Veritas licenses NetBackup SAN media servers.SAN media serversWhen the Shared Storage Option is installed, a tape drive that isshared among hosts is termed a shared drive. For the drives thatare attached to NDMP hosts, each NDMP attach host is consideredan additional host.Shared driveAbout the Shared Storage Option licenseThe Shared Storage Option is a feature that is licensed separately from baseNetBackup. The NetBackup Shared Storage Option license is based on the numberof physical tape drives to share. The license activates NetBackup to share thespecific number of physical drives for which you are licensed.About Shared Storage Option prerequisitesTo configure your hardware for use with Shared Storage Option, you must ensurethat the following prerequisites are satisfied:■Configure your SAN environment.■Attach robots and drives.■Ensure that all of the servers recognize the shared devices. Device recognitionmay depend on operating system configuration, as follows:On UNIX or Linux servers, you may have to modify configuration files, such asthe sg driver on Solaris systems.
