Understanding HP Instant Capacity (iCAP) version 6.x and 7.x Codewords Whitepaper
Effects of applying codewords
Codewords are applied with the icod_modify –C <codeword> command. This command
decodes the codeword and makes the appropriate modification to the iCAP inventory for the system.
The command only has to be applied once for the entire system. If there are multiple partitions on the
system, it doesn’t matter which partition is used to apply the codeword. Following are examples of
applying the various types of codewords to a system. Each example will show the output of
icod_stat before and after the application of the codeword.
Applying an add-on codeword
In this example, the system starts out having rights to use all cells, cores, and memory. An add-on
codeword is applied, resulting in the system having two expected-inactive cores. Because all cores
were activated prior to application of the codeword, immediately after applying the codeword the
system is in an exception state because more cores are activated than expected. To get the system
back in compliance, two cores must be deactivated.

Application of the add-on codeword
# icod_modify -C w6g8s0Q.P3XzB7n.188hnqm.Ri6Wbdd-
jDiiK3s.jja6nuq.QP9kB2A.FyGAjh4
The following valid codeword has been applied to the complex:
Add-On Codeword
2 CPUs
NOTE: This complex is not presently in a compliant state. You should now
add the additional iCOD components (cells, CPUs, memory), and/or
deactivate these components.
Use icod_stat(1M) to see the results of the application of this codeword.
Result of applying the add-on codeword
Consider the note printed by the icod_modify command, shown above. When the add-on
codeword was applied to the system, it increased the expected-inactive core count. To remain in
compliance, two cores must now be deactivated.
The output of icod_stat below shows the system to be in an exception state.
