Explanation
This is an informational message that is issued
by SMS during creation of a new SMS-managed data set or extension
of an existing SMS-managed data set to a new volume.  This message
indicates that fast volume selection approach is used by SMS to allocate
the data set. Fast volume selection is requested via FAST_VOLSEL parameter.
For striping allocations, fast volume selection is automatically activated
regardless of the specification of the FAST_VOLSEL parameter. When
fast volume selection is used, SMS will first select volumes normally
until 100 volumes have been rejected for insufficient free space.
 At this time, SMS issues this message and excludes volumes that do
not have sufficient free space in SMS volume statistics from further
selection.

function if normal volume selection is desired.

Programmer response
Determine if the data set is allocated or
extended as expected, and use volume selection failure reasons to
