IAR007I RSM COMPONENT TRACE DATA SPACE IS NAMED "SYSIARnn".

Explanation
The operator started the real storage manager (RSM)
component trace using the TRACE CT operator command and requested
that RSM use a data space for its trace buffers.
If the TRACE
command specified NODMPOFF but not DMPREC, the system does not dump
these buffers. The operator has to request a dump.
In the message
text: SYSIARnn
The name and number of the data space.

System action
The system starts the RSM component trace.  RSM
uses data space SYSIARnn to contain the trace data.

Operator response
Use the data space name in this message to
obtain the RSM trace buffers in an SVC dump requested by a DUMP command
or in a stand-alone dump. However, to obtain the dump when the RSM
trace is turned off or through the use of the DMPREC option, the data
space name is unnecessary.
