Adding paging space

To add paging space for page data sets on DASD HDDs, you must use the DEFINE PAGESPACE command of Access Method Services to pre-format and catalog each new page data set. To add the page data set, you can use the PAGEADD operator command, or specify the data set at the next IPL on the PAGE parameter.

To dynamically add paging space to storage-class memory (SCM) on Flash Express® SSDs, use the CONFIG ONLINE command. For complete command usage information refer to z/OS MVS System Commands.

For more information refer to the following information:

See z/OS DFSMS Access Method Services Commands for information about the DEFINE PAGESPACE command, and on the related commands - ALTER and DELETE - used for the handling of VSAM data sets.
See z/OS MVS System Commands for a description of the PAGEADD command.
See the description of the PAGE parameter in parmlib member IEASYSxx in z/OS MVS Initialization and Tuning Reference.
