HP Instant Capacity Version 10.x User Guide (762794-001, March 2014)

HP sends you a letter that tells you on how to acquire RTU codewords for the purchased components.
The letter also describes how to apply the codewords to the system to increase the usage rights
on the complex. The steps are as follows:
1. Acquire the appropriate RTU codeword (cell board, memory, core) from the Utility Pricing
Solutions portal (http://www.hp.com/go/icap/portal).
2. Apply the appropriate RTU codeword (cell board, memory, core) using the icapmodify -C
command.
NOTE: If multiple RTU products are purchased at one time, a single codeword can be generated
that incorporates multiple usage rights for the different components.
IMPORTANT: RTU codewords are based on both the serial number of a system and a unique
sequencing value for that server. These codewords must be applied in the sequence in which they
are obtained for a particular server. They can be applied to any partition on the server.
For an alternative to purchasing usage rights, see Chapter 7 for a discussion of GiCAP and how
you can borrow usage rights from other members of a GiCAP group.
iCAP cell board and considerations of core usage rights
At least one core usage right must be available for an iCAP cell board you want to activate. Each
active cell board must have at least 1 active core. However, you do not necessarily need to acquire
additional core usage rights. No additional core usage rights are required unless the requirement
for a minimum of 1 core per active cell board cannot otherwise be met. If the number of active
cores in an nPartition equals (or exceeds) the number of cell usage rights, then you do not need
to purchase additional core usage rights.
NOTE: The following examples assume that the number of intended active cores for the nPartition
remains constant before and after cell board activation.
For example, consider an nPartition with 1 active cell board with all 4 cores active, and 1 inactive
cell board with 4 inactive cores. The number of intended active cores for the nPartition is 4. No
additional core usage rights are available. Activation of the inactive cell board on the complex
results in 2 active cores per cell board after reboot. That is, the iCAP software distributes the
available core usage rights across the 2 active cell boards in the partition. The requirement that
at least 1 core is active on each cell board is satisfied, so purchase of additional core usage rights
is not necessary. You can choose to activate additional cores in the partition. If you do so, you
should purchase core usage rights at the same time as the cell usage rights. In this instance, it is
not required.

No additional core usage rights are required
because the number of core usage rights is greater
than the number of active cell boards.

In a different scenario, activation of an additional cell usage right can cause the number of core
usage rights to be below the minimum (1 active core per active cell board) and necessitate the
acquisition of additional core usage rights. For example, consider an nPartition with 1 active cell
board containing 1 active core and 3 inactive cores, and 1 inactive cell board with 4 inactive
cores. The number of intended active cores is 1 and there are no available core usage rights on
the complex. In this case, purchase of an additional cell usage right for the inactive cell board
