Storage Management Administration & Exploitation

Objectives
On successful completion of this course, attendees will be able to:

• explain IBM's storage management concept as implemented through SMS
• exploit the hardware features utilised by SMS
• define I/O devices and get them recognised by z/OS
• define VTOCs and VTOCIXs
• administer ICF Catalogs
• define and maintain data classes, storage classes, management classes and storage groups
• write and maintain optimised ACS routines
• audit and optimise the SMS environment
• describe the functions of HSM.

Who Should Attend
This course is primarily designed for those responsible for the z/OS Data Storage environment. It is primarily designed for Storage Administrators but is also suitable for technical support and senior operations personnel.
