• Select the Online radio button to take the physical library or partition to an online state, which
is the normal operating condition. In this mode, the robotics are enabled and all host com-
mands are processed.
• Select the Offline button to take the physical library or partition to an offline state. If only the
physical library is taken offline, the library partitions will not process robotics commands,
even though they are online. If only a partition is taken offline, neither the physical library
nor the other partitions are affected.
3. Select either Online or Offline, and then click OK.
4. If you selected Offline, a message appears that asks you whether you want to continue. If you
are sure that no backup applications are using the library, click Yes.
Online and Offline Functionality
Some library functions require the physical library or partitions to be in a particular state (either online
or offline) before they can be performed. If you choose a function that requires the library or partition
state to be changed from its current state, you are prompted to do so.
Table 14 summarizes the library functions that require the physical library or partitions to be either
online or offline.
