"Usually, page data sets specified by any means must have been allocated, cataloged in the system's master catalog, and preformatted in VSAM format before an IPL can start." "It is unnecessary to specify either UNIT or VOLSER because all page data sets must be cataloged in the system's master catalog." It might be possible to use PAGEADD to add a page data set that is cataloged in a user catalog, but I wouldn't be surprised if that leads to problems at the next IPL Surely, at CLPA time the Catalog address space is not yet available. -- Tom Marchant On Wed, 22 Nov 2023 17:32:26 +0000, Mark Jacobs <markjac...@protonmail.com> wrote: >Our storage administrator had told me that in a previous organization they >successfully used page datasets that were cataloged in a user catalog rather >that in the master catalog by using an MLA in the MCAT.
