10 Import tape cartridges to the correct library partitions as needed.
11 Save the library configuration (see Saving the Library Configuration
on page 495.
12 If the host application inventories the location of each tape cartridge
in the library, open the host application and reinventory in order to
sync its logical inventory with the physical inventory of the library.
Due to the way the library logically addresses its tape drives and slots
internally, permanently removing an expansion module from the
library will change the element addresses, and this can affect proper
communication to a controlling host. See Understanding Logical
Element Addressing on page 35. Because of this, you must refresh the
configuration of any backup application that manages the library to
reflect the adjusted positions. In addition, you may need to reboot
the host server(s) or rescan the bus to detect the changes.
Replacing the Control Module
These instructions explain how to remove a control module and replace it
with a control module field replaceable unit (FRU). You may need to
replace the control module if its chassis is severely damaged. Typically,
however, only certain customer replaceable units (CRUs) or FRUs within
the control module need to be replaced.
There are some configuration settings to take into account when
replacing the control module.
• If you have applied one or more license keys to the original control
module, you will need to replace each license key and apply it to the
new control module. For more information, see Obtaining and
Installing a License Key on page 88.
• A partition with all resources in the removed module will be present
with no slots or drives. This partition can only be deleted.
There are no restrictions on where the control module can be installed in
the library configuration. However, the recommended placement of the
control module for library configurations up to 32U is on top of all
installed expansion modules. The recommended placement of the control
