5.3.11 Logical Control Unit Activity File (SCPLCU)


The Logical Control Unit Activity File captures data on
logical and physical control unit activity and other I/O
configuration-dependent queuing delays.  There is one record
for each logical control unit defined.  It summarizes the I/O
measurement data down to the logical control unit level.

This file is derived from the CA MICS Device Activity,
Logical Channel/CU Activity, and I/O Queuing Configuration
files.

The following sections describe the file's organization, list
the data elements maintained, and provide usage hints.
