Start the server

Use this topic to select a method for starting your server and handling problems with IPL.

Some changes to the system settings or hardware configuration require the iSeries™ server to go through a startup sequence called an initial program load (IPL). During an IPL, system programs load from the designated load source device in the system auxiliary storage. The system hardware is also checked. The iSeries server control panel displays a series of system reference codes that indicate its current status and warn you of any problems. When the IPL is finished, the character-based interface presents the sign-on display, and users will be able to sign on with iSeries Navigator.

During the IPL, the control panel displays a series of system resource codes (SRCs) indicating the current system activity.

There are various options for starting an iSeries server.

• Start the system without making configuration changes (unattended IPL)
  This is the most common way to start the iSeries server. This topic provides instruction on how to start your system during normal operation.
• Change the system during IPL (attended IPL)
  Some situations might require you to enter information or change system values during an IPL. This topic provides instructions for performing a manual IPL.
• Change your system IPL from the control panel
  You can specify the type of IPL you need to perform from the system control panel.
• Change the IPL startup program
  Create a startup program that will change the system resources, and the resources and attributes assigned to them, that are started during an initial program load (IPL). Typically, subsystems, writers, and the Operational Assistant are launched by this program.
• Schedule a system shutdown and restart
  Set up a schedule that automatically powers your system on and off. You can determine the time of day you want the system powered on and off. You can also specify special circumstances that change the normal daily schedule, such as a holiday or special closing.
