System Action and Operator Response: Depending
on the system action, the operator does one of the following:
For
a cold start: The system issues message IEA922D. In response, choose
a new data set name or the IGNORE option.
For a quick start: For a PLPA or local data set, the system issues message IEA922D.
In response, choose a new PLPA or local data set name or the IGNORE
option.
For a COMMON data set, if the PLPA pages did not overflow to the
data set on the cold start associated with this quick start, the system
issues message IEA922D.  In response, the choose a new COMMON data
set name or the IGNORE option. For a COMMON data set, if PLPA pages
overflowed to the data set, the quick start cannot continue.  The
system forces a cold start, issues message IEA929I, and then issues
message IEA922D.  In response, choose a new COMMON data set name or
the IGNORE option.

For a warm start: For a PLPA data set, the system issues message IEA922D.  In response,
choose a new PLPA data set name or the IGNORE option.  The new PLPA
data set must have been used on a previous cold start; otherwise,
the warm start will fail and a cold start is forced.
For a COMMON data set, if PLPA pages did not overflow to the data
set on the cold start associated with this warm start, the system
issues message IEA922D.  In response, choose a new COMMON data set
name or the IGNORE option. For a COMMON data set, if PLPA pages
overflowed to the data set, the warm start cannot continue.  The system
forces a cold start, issues message IEA929I, and then issues message
IEA922D.  In response, choose a new COMMON data set name or the IGNORE
option.  The local page data set information is not preserved.

For a local page data set that contains VIO pages, the warm start
cannot continue.  The system forces a quick start and issues message
IEA930I. For a local page data set that contains no VIO pages,
the warm start continues.  However, the data set is not used as the
local page data set for this IPL.
