Dedicated service tools
Use dedicated service tools (DST) to work with Licensed Internal Code, disk units, configuration and resources, and to verify devices and communications. You can also use DST to 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.
System service tools (SST) provide a way to access a subset of the service tools that DST offers without requiring access to DST. SST is available when IBM® i is operational, and can be accessed using the STRSST CL command.
Dedicated service tools requirements
- The 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.
- Access to the system partition using an attached workstation.
- A valid service tools user ID and password to sign on to DST. IBM supplies service tools user IDs that have different levels of privileges. For more information, see Work with service tools user IDs.
To make a printout, attach the printer to the workstation I/O processor or storage media unit that is performing the service function. The printer that is used with DST for service tool output must be an SCS-type data stream printer.
