An Instant Capacity cell board is usually assigned to an nPartition; however, it does not participate in the boot of the nPartition. Activating an Instant Capacity cell board is a two step process:
Set the cell board’s use-on-next-boot flag to “y” (yes) using the parmodify command
Perform a reboot of the nPartition (using the shutdown -r command on HP-UX)
Example 6-3 Activating a cell board in cabinet 0, slot 5, nPartition 3 (HP-UX)
For example, changing the use-on-next-boot flag to “y” on the Instant Capacity cell board in cabinet 0, slot 5, in nPartition 3 can be accomplished via the following command:
/usr/sbin/parmodify -p 3 -m 0/5::y:
If there are core usage rights available in the complex, the number of Intended Active cores is increased as high 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 performed the reboot, 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.
See the HP System Partitions Guide for details about adding and configuring cells in nPartitions.
