Implementing Changes to Licensed Capacity

96116 • Revision: KA Chapter 5 Capacity on Demand 141

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.
