The document is intended for anyone using the features and functionality of IBM OMEGAMON for Storage on z/OS.
OMEGAMON for Storage on z/OS is the comprehensive monitor for z/OS® I/O subsystem performance and storage availability. The product combines comprehensive storage performance monitoring with a flexible, easy-to-use browser interface that helps you clearly understand storage conditions and ensure optimal performance. Specifically, you use OMEGAMON for Storage on z/OS to manage the performance and availability of mainframe attached storage (including disk, tape devices, and virtual tape devices) and the data sets that are located on them. It also supports for virtual tape subsystems that includes integration and compatibility with Generation 2 of the VTS (Virtualization Engine device model TS7700) and its new architecture for collecting and presenting performance and availability metrics.
- Data Facility Systems Managed Storage (DFSMS), which manages the service levels and priorities of data sets, based on user created storage goals.
- Data Facility Hierarchical Storage Manager (DFSMShsm), which provides functions for backing up and recovering data, and managing space on volumes in the storage hierarchy.
- Data Facility Removable Media Manager (DFSMSrmm), which is a functional component of, and shipped as part of, DFSMS. DFSMSrmm manages removable media resources for the z/OS environment, including automatic libraries like the IBM Virtual Tape Server.
The features of OMEGAMON for Storage on z/OS include the ability to perform trending and other historical analysis, and the ability to monitor user-created groups of volumes.
