    Note: If you perform an IPL on the logical partition before you exit DST, the next OS/400 IPL will be abnormal. To avoid an abnormal OS/400 IPL, exit DST before you perform the IPL. Then sign on to that logical partition and perform the IPL. AS/400e: Logical Partitions: Managing...
  • Page 11 These steps affect how they system stops active jobs when you start DST, including the system partition’s service function. You may need to wait five minutes before starting service functions in DST that were active in SST when you entered option 21. To force DST from SST follow these steps: 1.
