Activation of an Instant Capacity Cell Board
An Instant Capacity cell board is usually assigned to an nPartition; however, the cell board does
not participate in the boot of the nPartition. Activating an Instant Capacity cell board is a two-step
process:
1. Set the cell board’s use-on-next-boot flag to y (yes) using the parmodify command.
2. Reboot the nPartition (using the shutdown -r command on HP-UX), or (on HP-UX 11.31
OEUR 0709 or later) a Cell Online Activation.
For example, to change the use-on-next-boot flag to y on the Instant Capacity cell board in
cabinet 0, slot 5, in nPartition 3, execute the following command:
/usr/sbin/parmodify -p 3 -m 0/5::y:
If core usage rights are available in the complex, the number of intended active cores is increased
to as high a number as possible, limited by the number of cores in the newly activated cell board.
The available core usage rights are automatically used in the cell activation. If there are no
available core usage rights, the number of active cores remains the same.
After you have set the cell board’s use-on-next-boot flag to y, and have rebooted the
nPartition, you can use the icapmodify command to activate cores that are listed as Additional
cores that can be assigned with current usage rights (as reported by the
icapstatus command).
Activating an Instant Capacity cell board causes at least one core to become active on that cell
board after reboot.
For details about adding and configuring cells in nPartitions, see the nPartition Administrator's
Guide.
