Starting and stopping the system
The System i® platform is well-known for rarely needing to be stopped or restarted. However, some maintenance items or system changes might require that the system stop processing and go through an initial program load (IPL). Stopping and starting the system must be done carefully.
Note: The procedures for starting and stopping the system depend
on whether you have a partitioned system. The following instructions are relevant
only for a system without logical partitions. If you have a partitioned system
without the Hardware Management Console, see Restarting and powering down a system with logical partitions.
If you have a partitioned system with the Hardware Management Console, see Partitioning
with System
i.
Regardless of how your system environment is configured, starting and stopping the system requires careful planning to prevent data loss and to protect system integrity. The IBM® i operating system provides several methods for starting the system to allow for various amounts of interaction with the user.
Note: Several system values determine the available options
for starting and stopping the system.
