2. Install the OS and iCAP software
To deactivate the cell board set the cell board’s use-on-next-boot flag to no:
# /usr/sbin/parmodify -p <partition #> -m <cabinet>/<cell>::n:
Reboot the nPartition, or (on HP-UX 11.31 OEUR 0709 or later) perform a Cell Online
Deactivation. This step is not necessary if there was no reboot after the activation.
Any cell board can be assigned to an nPartition with the use-on-next-reboot flag set to “n” (no),
whether usage right are available for activation or not.
Temporary Instant Capacity – TiCAP
You can purchase an amount of temporary capacity (TiCAP) time for inactive cores without
usage rights in your Instant Capacity system. Temporary capacity can be purchased in units of 30
processing days. Temporary capacity allows one or more inactive cores to be activated for up to
the specified period of prepaid processing time, without requiring permanent usage rights for the
cores. You can also temporarily activate one or more cores using the Instant
Access Capacity (IAC) provided with the purchase of Instant Capacity processors.
To use TiCAP or IAC:
1. Acquire a TiCAP or IAC codeword from the iCAP web portal located at
http://www.hp.com/go/icap/portal.
2. Apply the IAC / TiCAP codeword using the command:
# /usr/sbin/icapmodify -C <codeword>
3. Activate the number of new cores needed using the command:
# /usr/sbin/icapmodify -t -a <# of cores> [desc[:user_name]]
to immediately activate the cores
# /usr/sbin/icapmodify -t -a <# of cores> -D [desc[:user_name]]
to defer the activation until the next reboot
Note: Ensure that all HP and third party software has the proper licensing for the number of core
activated. If an application is running when an additional core is activated, it may not recognize
