谢谢你的回复！
不过我觉得不应该是media server来控制robot，我的理解是media server只存取磁带机，不控制robot. robot应该是master 或者emm进行集中控制的，但我也不确定。
ENTERPRISE MEDIA MANAGER
The Enterprise Media Manager (EMM) consolidates all media and device information into a single
relational database. When volumes are added, they are recorded in the relational database. The
NetBackup resource broker can then query the database in order to allocate storage units, drives
(e.g., including drive paths), and media. The restructuring allows for improved performance,
scalability, and manageability of NetBackup media and devices.
...
The three main elements of Veritas NetBackup Enterprise Media Manager are as follows:
• Robot management—Supports robotic secondary storage devices
• Device management—Lets you share secondary storage devices among different users and
applications
• Media management—Tracks the location of all removable media and secondary storage
devices in your system and gathers media usage statistics
...
The Veritas NetBackup EMM enables multiple backup servers to share a multi-drive tape library.
One NetBackup server acts as the “robotic control host,”
俺没参加过nbu培训，你看这篇文章的描述，表面上看好像是EMM进行了设备和介质的管理，其实仔细看只是提供了一个逻辑的管理，并没有控制
可以想像一下一个备份域中有多个server，每个server控制多个带库的情况，很常见：） |
