Changing From a Process
Pair to a Single Process
and Changing the Primary
CPU
Assume that the NCP is running in CPUs 0 (primary) and 1 (backup), and that you
want the NCP to run in CPU 2 only, with no backup process. To do so, follow these
steps:
1. Enter the following command to update the backup process CPU value and to
implement the change:
PROCESS ALTER=$ZNNM BACKUPCPU=2 DEFER=NO
When the command finishes, the NCP is running in CPUs 0 (primary) and 2
(backup).
2. Enter the following command to switch the roles of the primary and backup
processes:
PROCESS SWITCH=$ZNNM
When the command finishes, the NCP is running in CPUs 2 (primary) and 0
(backup).
3. Enter the following command to update the backup process CPU value and to
implement the change:
PROCESS ALTER=$ZNNM BACKUPCPU=2 DEFER=NO
When the command finishes, the NCP is running in CPU 2, with no backup
process.
Changing From a Single
Process to a Process Pair
Without Changing the
Primary CPU
Assume that the NCP is running in CPU 0 only, with no backup process, and that you
want the NCP to run in CPU 0 (primary) and 1 (backup). Use the following command
to update the backup process CPU value and to implement the change:
PROCESS ALTER=$ZNNM BACKUPCPU=1 DEFER=NO
When the command finishes, the NCP is running in CPU 0 (primary) and 1 (backup).
Changing From a Single
Process to a Process Pair
and Changing the Primary
CPU
Assume that the NCP is running in CPU 0 only, with no backup process, and that you
want the NCP to run in CPU 2 (primary) and 3 (backup). To do so, follow these steps:
1. Enter the following command to update the backup process CPU value and to
implement the change:
PROCESS ALTER=$ZNNM BACKUPCPU=2 DEFER=NO
When the command finishes, the NCP is running in CPUs 0 (primary) and 2
(backup).
2. Enter the following command to switch the roles of the primary and backup
processes:
PROCESS SWITCH=$ZNNM
When the command finishes, the NCP is running in CPUs 2 (primary) and 0
(backup).
