the partition. The exception is the monarch processor as it cannot be deactivated by the LPMC
monitor. The failed core is marked for deconfiguration during the next system reboot.
If an active core fails with a High Priority Machine Check (HPMC), then upon reboot the failed
core is deconfigured and its processing capacity is instantly replaced by an inactive core, if any
are available in the partition.
Activating and Deactivating iCAP cells and memory
An appropriate Right to Use (RTU) codeword is required to activate new cell boards. Purchase
the RTU for the cell as well as the usage right for all of the memory of the cell board as you
cannot activate a cell without activating all memory on that cell. Depending on the available
number of core RTUs in the complex you may also need additional RTUs for cores. An active
cell board must have a minimum of 1 active core.
However, when a new partition is created via the parcreate command, core usage rights must be
available for all cores configured on the new partition's cells, and core usage rights are
automatically assigned to these new cells.
To activate a cell board:
1. Purchase RTU (Right To Use) for cell(s), the entire amount of iCAP memory on the cell
board and any cores (if needed).
2. Acquire the RTU codewords from the iCAP portal located at
http://www.hp.com/go/icap/portal. The output of “icapstatus -s” and the Sales Order
Number are needed.
3. Apply the RTU codewords using the command:
# /usr/sbin/icapmodify –C <codeword>
4. Activate the new cell board using the command:
# /usr/sbin/parmodify –p <partition #> -m <cabinet>/<cell #>::y:
5. Reboot the nPartition.
Or
1. Create a new partition using the command:
# parcreate -P <partition name> -c <cabinet #>/<cell #>:base:y:ri
