Implementing Changes to Licensed Capacity

Implementing Changes to Licensed
Capacity
Increasing Licensed Capacity
Following are special considerations for installing new licensed storage capacity.
■
See “License Installation Process” on page 120 for details on purchasing and
installing a Capacity license.
■
If the new licensed capacity exceeds the physical capacity, no corrective action is
necessary. Physical cells that cannot be activated due to licensed capacity limits will
be activated later whenever additional licensed capacity is installed.
■
You must configure all affected library host applications to recognize the new
licensed storage cells. See “Host Notification of Capacity Changes” on page 142 for
details.
■
In non-partitioned libraries, all newly licensed cells are immediately available for
use.
■
In partitioned libraries, all newly licensed cells are added as “unallocated,” and are
therefore not available for use. You must manually allocate the new cells to
partitions before the cells can be used for cartridge storage. See “Partition
Configuration Tasks” on page 156 for detailed instructions.
Decreasing Licensed Capacity
Following are special considerations for deleting licensed storage capacity.
Caution – Deleting licensed capacity is an exceptional situation; use caution when
doing so.
■
See “Delete a License Key File” on page 126 for details on deleting licensed capacity.
■
Storage cells corresponding to the reduced capacity will become inaccessible, and
any cartridges within those cells will be orphaned. No checks are made to identify
cartridges that will be orphaned. See “Orphaned Cartridges in Non-Partitioned
Libraries” on page 140 for details.
■
You must configure all affected library host applications to recognize the licensed
storage cell changes. See “Host Notification of Capacity Changes” on page 142 for
details.
■
For partitioned libraries:
■
The total number of storage cells allocated to all library partitions cannot exceed
the licensed capacity of the library.
Caution – You must manually de-allocate cells from partitions so the total allocation
does not exceed the new licensed capacity.
