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

IMPORTANT: To avoid a delay in activation of additional cores, purchase and keep in reserve
some quantity of temporary capacity for the system. Temporary capacity can be used to instantly
and temporarily activate cores while waiting for an RTU codeword. For details about temporary
capacity, see Chapter 5. You can also temporarily activate one or more cores using the Instant
Access Capacity (IAC) provided with the purchase of iCAP processors.
iCAP cell board
iCAP Cell Board allows you to have additional (inactive) cell-board capacity in your system for
growing business needs. When the need arises, you can purchase additional cell and memory
usage rights; then the inactive cell boards, which contain memory and cores, are available for
instant activation and use.
The iCAP software monitors and enforces the count of inactive cell boards (those without usage
rights) throughout the complex. Inactive cell boards assigned to a partition have the use-on-next-boot
flag set to n (no).
After applying a cell board and memory codeword to convey additional usage rights, you may
activate any cell board with memory not exceeding the amount allowed by the available memory
usage rights, and configure the cell into an nPartition. This is controlled by setting the use-on-next-boot
flag to y (yes) with the parmodify command after the cell is configured and assigned to the
partition, and then rebooting the nPartition.
IMPORTANT: An active cell board must have a minimum of one active core; therefore, you must
also have sufficient core usage rights on the complex to activate at least the one core per cell
board. The iCAP software redistributes active cores across all cell boards of the partition. TiCAP
can be used to activate this core but the system needs to have at least one core usage right for
each active cell. Also, if you are creating a new partition for the new cell board, additional
constraints apply and you might need to acquire additional core usage rights. For more information
see “New partition creation and Instant Capacity” (page 204).
For more information about iCAP Cell Board, see Chapter 6: “iCAP cell board” (page 62).
iCAP software validation
On HP-UX systems
The iCAP software (HP-UX product B9073BA) is installed by HP manufacturing on instantly ignited
HP-UX systems. The iCAP software can also be installed by an HP service representative on existing
(supported) HP-UX enterprise servers as an add-on.
NOTE: The iCAP software is automatically installed when the HP-UX 11i v3, 11i v2, or 11i v1
Operating Environment (OE) is installed.
To verify the iCAP software is installed on your system, execute the following HP-UX command:
/usr/sbin/swlist -l product iCOD
Output similar to the following is displayed:
iCOD B.11.23.09.00 HP-UX iCOD Instant Capacity
To verify that the iCAP software installation has not been corrupted, execute the following HP-UX
command:
/usr/sbin/swverify iCOD
The command will display the message Verification succeeded.
On OpenVMS systems
On OpenVMS systems, the iCAP software is automatically installed on partitionable systems when
the OpenVMS Version 8.3 or later operating system is installed. You should not need to install the
