Activation of an Instant Capacity Cell Board
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 that is licensed is a two step process:
Step 1. Set the cell board’s use-on-next-boot flag to “y” (yes) using the
parmodify command
Step 2. Perform a reboot of the nPartition (using the shutdown -r command)
Example 6-3 Activating a cell board in cabinet 0, slot 5, nPartition 3
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 available licensed processors in the complex, the number of
intended active processors is increased as high as possible, limited
by the number of processors in the newly activated cell board. The
available processor licenses are automatically used in the cell activation.
After you have set the cell board’s use-on-next-boot flag to “y”, and
performed the reboot, you can use the icod_modify command to activate
processors that are listed as inactive processors that can be
activated (as reported by the icod_stat command).
The number of active processors in the nPartition remains the same
after the cell board is made active — unless prior to the cell board’s
activation the number of intended active processors is greater than
the number of active processors (as reported by the icod_stat
command).
Activating an Instant Capacity cell board causes at least one processor to
become active on that cell board.
IMPORTANT The above parmodify command fails if a licensed processor is not
available for activation on the newly activated cell board.
