IGD17051I

Explanation
This message is issued only for non-VSAM data
sets that are not managed by SMS. During allocation of the specified
data set, the primary space allocation exceeded the maximum, which
is: 65,535 tracks for a data set type that does not support this
size
16,777,215 tracks for DSNTYPE=LARGE (large format sequential data
sets)

The system issues this message when the requested space
quantity exceeds the maximum allowed on a single volume. Since SMS-managed
data sets may be spread over multiple volumes during space constraint
relief processing, SMS treats this particular DADSM failure as one
that is re-tryable. However, there are some SMS-managed allocations
that cannot be spread over multiple volumes. In these cases, SMS issues
IGD17051I as soon as the error is detected rather than go through
a length retry process that will eventually fail anyway. This will
apply to non-VSAM SMS-managed data sets only. 
Note: Some types
of data sets are limited to 65,535 total tracks allocated on  any
one volume.  For such data sets, if more than 65,535 total tracks
on the target DASD device are required to satisfy the primary space
request, the data set creation will fail.DSNTYPE=LARGE is limited
to 16,777,215 tracks.
If a secondary space allocation would
result in more than 65,535 total tracks or for DSNTYPE=LARGE more
than 16,777,215 total tracks allocated on this volume for such
a data set the secondary allocation will fail on this volume, and
the system will try on another volume if the volume count in the data
class or on the DD statement allows another volume. 
Types of
data sets which are not limited to 65,535 total tracks allocated on
any one volume are:  Extended format
HFS
PDSE
VSAM
Large format sequential (limited to 16,777,215 tracks)

In the message text: dsname
The specified data set name.

System action
The SMS VTOC Data Set Services request fails.

User response
Specify a smaller primary space quantity.

Programmer response
Reduce the amount of primary space and resubmit
the job.
