Introduction

Dedicated service tools (DST) is used to service Licensed Internal Code (LIC), work with disk units, work with configuration and resources, verify devices and communications, and display logs on the system.

DST operates in stand-alone, limited, and full paging environments. The DST tools and functions vary depending on the paging environment and the release level of the operating system. For more information, see “System paging environments” on page 2.

System Service Tools (SST) provides a way to access a subset of the service tools that DST offers without requiring access to DST. SST is available when OS/400 is operational, and can be accessed using the STRSST CL command.

Dedicated Service Tools requirements

Attention: It is a requirement to change the password the first time anyone signs on to DST or SST. The customer engineer needs to give the new (changed) password to the customer or have the customer change the password.

To use DST, you must have the following items:

vThe disk that contains the Licensed Internal Code (the load-source disk).

Note: When you perform an alternate initial program load (IPL) to DST, you do not need the load-source disk.

vAn operational workstation on bus 1 as either a primary console or an operations console.
