USING AN ALIAS VOLUME NAME FOR A VOLUME TO ALLOCATE SPACE TO A DATA SET

摘要

Provided are a computer program product, system, and method for using an alias volume name for a volume to allocate space to a data set. An assignment of a plurality of volumes to a data set is maintained, wherein the volumes are configured in a storage system. A request is received to extend the data set. An alias volume name is assigned to the data set for a previously assigned volume to the data to extend the data set in response to one of the previously assigned volumes having available space to extend the data set. A base volume name is assigned to the data set for a volume not assigned to the data set in response to one of the previously assigned volumes to the data set not having available space to extend the data set.

1. A computer program product to allocate space in volumes to data sets in a storage system, the computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therein that executes to perform operations, the operations comprising:
maintaining an assignment of a plurality of volumes to a data set, wherein the volumes are configured in the storage system; receiving a request to extend the data set; assigning a secondary allocation amount of available space from a current volume from which space was last assigned to extend the data set in response to the current volume having available space to extend the data set; and assigning a primary allocation amount of available space from a previously assigned volume comprising one of the volumes assigned to the data set other than the current volume having sufficient available space for the primary allocation amount when the current volume does not have available space for the secondary allocation amount base.
