IBM VERSION 5 SY44-5902-05 - Manual (Page 116)

The Licensed Internal Code maintains a 128KB shadow log on the load-source
disk. The log contains a duplicate copy of the latest entries. When you perform an
IPL to Dedicated Service Tools (DST), the Product activity log option uses this
shadow log.
Note: The shadow log is not available in the stand-alone environment (Type-D
IPL). In the limited paging environment, some options are not available. For
more information on paging environments, see “System paging
environments” on page 2.
