Overriding Deferred Processor Activations and Deactivations
Chapter 462
Overriding Deferred Processor Activations
and Deactivations
NOTE Only activation of processors is discussed in this section, but deactivation
of processors also applies.
If you have performed a deferred processor activation, using the -D
option in the icod_modify command, and the requested number of
active processors specified is no longer desirable, you can override the
(pending) deferred activation by performing another deferred or instant
icod_modify operation, which overrides the first activation.
You may experience one of the following deferred activation scenarios:
• The specified number of active processors was incorrect and you
want to correct it, and apply the change, when the system reboots
• The entire operation was accidental and you want to undo it
Two examples are used to explain how to override these situations.
Example 4-2 Correcting an Incorrect Number of Deferred Active Processors
1. On your system or partition you currently have 2 processors
activated and 2 processors inactive. You decide 4 active processors
are needed, so you perform a deferred activation for 2 additional
active processors by entering the following command:
icod_modify -D -a 2 [desc]:user-name:mgr-name:mgr-email:mgr-phone
2. Later, and prior to a system reboot, you realize that you need only 3
active processors (not 4). You can override the initial deferred
activation in
Step 1 by entering the following command:
icod_modify -D -s 3 [desc]:user-name:mgr-name:mgr-email:mgr-phone
The -s option in Step 2 (above) sets the number of active processors. The
activation takes place after the next system reboot due to the -D option.
You could also perform Step 2 without the -D option for the icod_modify
operation to be instant.
