B<chvm> - Changes HMC- and IVM-managed partition profiles. For P7 IH, chvm only could be used to change the I/O slots assignment to LPARs.
B<chvm> - Changes HMC- and IVM-managed partition profiles. For P7 IH, chvm could be used to change the octant configuration values for generating LPARs; change the I/O slots assignment to LPARs within the same CEC.

=head2 PPC (using Direct FSP Management) specific:
chvm is designed to assign the I/O slots to the new LPAR. Both the current IO owning lpar and the new IO owning lpar must be powered off before an IO assignment. Otherwise, if the I/O slot is belonged to an Lpar and the LPAR is power on, the command will return an error when trying to assign that slot to a different lpar.
chvm could be used to change the octant configuration values for generating LPARs. chvm is designed to set the Octant configure value to split the CPU and memory for partitions, and set Octant Memory interleaving value. The chvm will only set the pending attributes value. After chvm, the CEC needs to be rebooted manually for the pending values to be enabled. Before reboot the cec, the administrator can use chvm to change the partition plan. If the the partition needs I/O slots, the administrator should use chvm to assign the I/O slots.

Otherwise, if the I/O slot is belonged to an Lpar and the LPAR is power on, the command will return an error when trying to assign that slot to a different lpar.
The administrator should use lsvm to get the profile content, and then edit the content, and add the node name with ":" manually before the I/O which will be assigned to the node. And then the profile can be piped into the chvm command, or changed with the -p flag.

partition rule.
If all the octants configuration value are same in one CEC, it will be " B<-r> B<0-7>:I<value>" .
If the octants use the different configuration value in one cec, it will be "B<-r> B<0>:I<value1>,B<1>:I<value2>,...B<7>:I<value7>", or "B<-r> B<0>:I<value1>,B<1-7>:I<value2>" and so on.
The octants configuration value for one Octant could be B<1>, B<2>, B<3>, B<4>, B<5>. The meanings of the octants configuration value are as following:
1 -- 1 partition with all cpus and memory of the octant
2 -- 2 partitions with a 50/50 split of cpus and memory
3 -- 3 partitions with a 25/25/50 split of cpus and memory
