DST in OS/400 limited paging environment

DST operates in stand-alone (non-paging), limited, and full paging environments.
The DST tools and functions vary depending on the paging environment (see
“System paging environments” on page 2) and the OS/400 operating system used.

The limited paging environment is available when you perform an IPL to DST. The
following options appear on the Use Dedicated Service Tools (DST) display for the
OS/400 operating system:
v Install the operating system
v Perform an IPL
v Perform automatic installation of the operating system
v Select DST console mode
v Start a service tool
v Work with disk units
v Work with DST environment
v Work with Licensed Internal Code
v Work with remote service support
v Work with system partitions
v Work with save storage and restore storage
v Work with system capacity
v Work with system security

For details on each DST option, see “DST options” on page 10. For general
information on DST, see Chapter 1, “Dedicated Service Tools (DST)” on page 1.

System Service Tools (SST)

The system service tools (SST) run one or more Licensed Internal Code (LIC) or
hardware service functions under the control of the operating system. To determine
whether the OS/400 operating system is running on your server, see “Determining
the dominant operating system” on page 126.
SST allows you to perform service
functions concurrently with the customer’s application programs. The printer that
is used for output must be an SCS-type data stream printer that is attached to the
same workstation input-output processor (IOP) or storage media unit.

Accessing system service tools

You can access SST only when the system is in the full-paging environment (see
“System paging environments” on page 2). The full paging environment is used
during normal system operation. All disk units, the Licensed Internal Code, and
the operating system are available.
