The program has successfully written to the volume or volumes whose serial numbers are listed after VOLS=. This volume list is either the complete volume list for the data set dsn after DSN= or the list of volumes to which the data set has been extended. This volume list might be a subset of the volume serial numbers specified in the DD statement and in message IEF285I. If applicable, this message indicates either that you requested extended capacity mode for emulation of the IBM® 3490 or that data blocks were written in the extended capacity area of one or more of the listed volumes.

In the message text:

ddname

The data definition name.

jobname

The job name.

stepname

The step name.

nnn

The decimal file sequence number of the tape data set that was created or extended.

dsn

The data set name.

volser

A list of volume serial numbers. The message lists up to eight volume serial numbers per line. If there are more than eight volume serial numbers in the message, there will be additional lines in the message until all the volume serial numbers have been listed. Each new line of volume serial numbers will begin with VOLS=.

mmm

The decimal multivolume total of data blocks for a data set. TOTALBLOCKS is omitted when a multivolume data set is extended starting on a volume other than the data set's first volume. It will also be omitted if the access method being used by the application isn't maintaining the block count in the DCB such as may be the case for the EXCP access method.
