Service tools functions

You can use dedicated service tools (DST) or system service tools (SST) to access service tools functions. DST is available when the Licensed Internal Code is started even if the operating system has not been loaded. SST is available from the operating system.

Service tools are used to perform the following actions. This list is not all inclusive but gives you an overview of the functions provided by service tools:

  • Add hardware resources to the system.
  • Diagnose system problems.
  • Manage disk units.
  • Manage logical partition (LPAR) activities, including memory.
  • Manage or view main storage dumps.
  • Manage other service tools user IDs.
  • Manage system security.
  • Manage the Take over console function, which allows a second LAN console to take over an existing LAN console.
    1. You need to enable the Take over console before using it. To do so, use the Select console menu.
    2. When attempting to take over an existing LAN console with a second LAN console, the user must have the Take over privilege or the Service tool security privilege.
  • Review the Licensed Internal Code and product activity logs.
  • Trace Licensed Internal Code.
