DST in OS/400 full 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 that is used.

The full paging environment is used during normal system operation. The following options appear on the Use Dedicated Service Tools (DST) display for the OS/400 operating system:

vPerform an IPL

vInstall the operating system

vWork with Licensed Internal Code

vWork with disk units

vWork with DST environment

vSelect DST console mode

vStart a service tool
