Tips and Troubleshooting 5-3
In general, it is reasonable practice to set auto_action to halt in each partition
when you are first starting up logical partitions. Once you are sure that the
partitions have been defined as you wish, you can install and boot the operating
system in each partition. Once you have partitions running smoothly, you can
make changes to auto_action as desired.
Partition 0: auto_action Set to halt
If auto_action is set to halt in partition 0, then after partitions are initialized
with the lpinit command, turning the keyswitch to Reset or issuing an init and
answering “Y” to the prompt will cause the system to initialize with partitions
disabled. The primary console will halt at the console prompt; secondary
consoles are disabled. You may then perform whatever actions you wish, and
issue an lpinit command to restart partitions as they were set previously, or as
you have changed them at the primary console.
If auto_action was set to halt at the secondary consoles, the secondary
partitions will initialize and halt at the console prompt. If auto_action was set
to boot at the secondary consoles, the secondary partitions will initialize and
boot the operating system.
Partition 0: auto_action Set to boot
If auto_action is set to boot in partition 0, then after partitions are initialized,
turning the keyswitch to Reset or issuing an init and answering “Y” to the
prompt will cause the firmware to initialize the system with partitions disabled.
The firmware will then boot the operating system in the primary partition, and
issue an lpinit automatically to restart partitions. The secondary partitions
will come up.
If auto_action was set to halt at the secondary consoles, the secondary
partitions will initialize and halt at the console prompt. If auto_action was set
to boot at the secondary consoles, the secondary partitions will initialize and
boot the operating system.
