SERVICE TOOLS

Difference between SST and DST

SST is available when the OS is started. The OS is required for accessing SST. SST is used to manage firmware & hardware. It is not used to manage OS.

DST is available even when the system has limited capabilities. DST is available even if OS is not installed. LIC is required for accessing DST.  

Accessing SST

To access service tools using SST, complete the following steps:
  1. Enter STRSST (Start SST) on an IBM i command line. The Start SST Sign On display is shown.
  2. Enter the following information:
    • Service Tools User ID: The service tools user ID you sign on with.
    • Password: The password associated with this user ID.
  3. Press Enter.
Note: To login to SST, the user ID must have Service (*SERVICE) special authority 


Service Tools

Service tools are used to perform various system functions including diagnosing system problems, managing disk units, and managing system security. 

Dedicated Service Tools (DST) or System Service Tools (SST) are used to access service tools functions.  The following are the few functions we can perform with DST or SST.
  • 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.
  • Review the Licensed Internal Code and product activity logs.
Service tools user IDs are user IDs that are required for accessing service functions through DST, SST, i series navigator (for disk unit management), and Operations Console. 

Service tools user IDs are created through DST or SST and are separate from IBM i (OS/400) user profiles. It is possible to have a service tools user ID and operating system user profile with the same name.


You can create a maximum of 100 service tools user IDs (including the four IBM-supplied user IDs).
