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.
The chvm command is used to set the Power 775 pending octant partition configuration value, the pending memory interleave value, and also is used to assign the I/O slots to an lpar within the CEC.
chvm is also 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.
The octant configuration value specifies one of five preset configurations. Each configuration specifies the number of lpars per octant and the percentage of CPUs and memory assigned to those lpars. The configuration values include:
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.

The memory interleaving value specifies how the memory is accessed within the octant and can be one of two values:
=over
=over
=item B<1> - interleaved or 8MC mode
Memory allocations are interleaved evenly across all eight memory controllers in the octant. This is the default value if -m is not specified. A value of 1 must NOT be specified if the octant is to be partitioned, i.e. have an octant configuration value of 2-5.
=item B<2> - non-interleaved or 2MC mode
Memory allocations are only interleaved across the two memory controllers on a local chip in the octant. A value of 2 MUST be specified if the octant is to be partitioned, i.e. have an octant configuration value of 2-5.
=back
=back
If octants in the same CEC are to have different memory interleaving values then they must be configured in separate chvm commands. For example, if octant zero is to have an octant configuration of 2 and octant one through seven are to have an octant configuration of 1 and a memory interleave value of 1 then the two commands would be:
chvm lpar1,lpar2 -i 1 -m 2 -r 0:2
chvm lpar3-lpar9 -i 5 -m 1 -r 1-7:1
The lsvm command can be used to verify the pending octant configurations are correct for the CEC.
To activate the pending configuration the CEC needs to be manually rebooted.
Once the CEC has the correct active configuration, the chvm command can then be used to assign I/O slots to new partitions in the CEC. Once again, the lsvm command can be used to display the current I/O slot assignments of the CEC. Before running the chvm command to update I/O slot assignments, ensure that both the current I/O owning lpar and the new I/O owning lpar are powered off. Otherwise, the chvm will return an error.
The lsvm command output can be redirected to a file. This file can then be edited to include only the current sixteen I/O slot assignments. A sample of some of the output is:
1: 537/U78A9.001.0123456-P1-C9/0x21010219/2/1
1: 514/U78A9.001.0123456-P1-C17/0x21010202/2/1
1: 568/U78A9.001.0123456-P1-C2/0x21010238/2/1
1: 561/U78A9.001.0123456-P1-C3/0x21010231/2/1
The number, as in the above example, or text before the ":" indicates the lpar id of the node or the node name. To change the I/O slot assignment, change this value to the new lpar id or node name, for example, 5 for lpar id 5 or use the node name "lpar5". For example:
1: 537/U78A9.001.0123456-P1-C9/0x21010219/2/1
1: 514/U78A9.001.0123456-P1-C17/0x21010202/2/1

5: 561/U78A9.001.0123456-P1-C3/0x21010231/2/1
This file can then be piped into the chvm command, or specified with the -p flag.

Octant partition configuration rule. The rule specifies the octant and the octant configuration value.
If all the octants configuration value are same in one CEC, it will be " B<-r> B<0-7>:I<value>" .
The format is " B<-r> B<octant_number:value>"
Multiple octants can be specified in the same rule: " 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.
