Alternatively, make sure that you are viewing the physical library
(from the View menu, click the name of the physical library), then
click Tools > Save/Restore .

Note: If the library is not offline, you receive a message that asks
you whether you want to take it offline. Click Yes .
3 At the prompt, check whether all library data input and output has
stopped. To continue, click Yes .
When the system determines that it can reconfigure the library
using the saved image, a message dialog box appears that informs
you that the library will reboot itself. The reset could take minutes to
complete. If you are near the library and can see the library’s touch
screen, normal behavior is when two “working” messages appear
and the touch screen goes dark when the LMC server restarts.
As the MCB reboots, the I/O blades, MCB, LMC server, and robotics
control unit (RCU) change to the configuration settings stored in the
rescue image. Each I/O blade is also reset.
When the LMC has restarted, reconnected, and completed its
discovery operation, a message appears that indicates that the
library has been restored to its previous configuration.
If the operation succeeds, a message appears that indicates that the
library has been restored to its previous configuration.
If the operation fails at any point, the library generates a RAS ticket
that provides that contains details about the failure. Perform a
revert or rescue to return the library to a stable configuration.
4 If you have not done so already, make sure that the robotics are
enabled and bring the library back online so that data input and
output can recommence.
