zSeries File System

zFS is another type of OMVS file system that can be used which can be mounted into the file system tree. zFS is not a replacement for HFS; in particular, the root file system must be an HFS.

Checking zFS Integrity

The IOEAGSLV program (the Salvager) can be used to verify zFS structural integrity. The zFS must not be in use; otherwise you will receive a message like "unable to open dataset". Refer to the publications below for parameter information.
