Adding Processor Capacity
To enable additional processors in the configuration of a system that has the Capacity
Upgrade on Demand feature installed and running, do the following.
1. To increase the number of authorized processors, type the following at the
command line:
chcod -r proc -n total_number_of_processors
The following is an example of the above command:
chcod -r proc -n 6
In the example above, the value of -n 6 is equal to the total number of processors
that you want to have authorized (yy) by entering this command. To upgrade your
system to use more of the installed processors, increase the value of (yy) in
increments of 2. In this case, 6 would represent 4 base processors plus 2 additional
Capacity Upgrade on Demand processors.
When the system performs the command to enable additional processors,
information about the new system configuration is added to the error log and sent
through the Electronic Service Agent to the service support center.
2. Shut down and reboot the system to enable the additional processors, as follows:
shutdown -Fr
3. Log in to the system as root user or as a user with system group privileges.
4. Type the following at the command line:
chcod
The following information displays:
Current MailAddress _______Reserved________
Current CustInfo Jane_Doe-CustomerNumber_9999999-Phone_(333)_444-5555
Current Model and System ID = IBM, xxxx-xxx_IBM,xxxxxxx
Current number of authorized proc(s) out of (xx_____) installed on system = (yy_____)
The values of (yy) should match the value you entered for the
total_number_of_processors
in step 1.
For details about the flag variables entered in the chcod command, see Appendix E,
“Using the chcod Command” on page 69.
