DFSMS Implementation - SS84G

DFSMS Implementation - SS84G

Audience

This is an intermediate course for individuals responsible for developing and implementing effective storage management techniques.

Prerequisites

You should complete:

  • An Introduction to Data Storage Subsystems - SS05G
  • Storage Management Fundamentals - SS06G

... or have equivalent knowledge.

Duration

4 days.

Course Objectives

Learn how to plan and implement DFSMS. Learn a step-by-step implementation strategy emphasizing coexistence considerations reinforced by hands-on labs. Learn how to manage temporary and permanent data sets with an emphasis on disk storage. Discuss exploitation of the functions provided by DFSMS as the installation evolves to the DFSMS environment.

Six hands-on labs are included to address:

  • Using Interactive Storage Management Facility (ISMF)
  • Activating System Managed Storage (SMS) with a minimal configuration
  • Managing temporary data sets
  • Managing permanent data sets
  • Volume and data set conversion to SMS
  • System operations

Hands-on lab projects may be done in teams depending on the number of attendees and location.

Course objectives include:

  • Establish a DFSMS configuration to automatically enforce your installation's storage management policies
  • Convert service level requirements into appropriate parameters for data class, storage class, management class, and storage groups
  • Create and test Automatic Class Selection (ACS) routines
  • Convert volumes and move data to system-managed volumes with DFSMS Data Set Services (DFSMSdss)
  • Specify appropriate management class and storage group parameters for DFSMS Hierarchical Storage Management (DFSMShsm) processing of system-managed data sets
  • Plan to maintain your DFSMS environment using Naviquest
  • Establish procedures to control, manage, and recover the storage management subsystem with ISMF and operator commands
  • Develop a DFSMS implementation plan

Course Content

Course Introduction and DFSMS Overview
Specify the storage administration functions that can be automatically performed by the system
Identify the types of data set services that need to be established by negotiating service level agreements
Correlate data set service requirements to the SMS configuration components: data class, storage class, management class, storage group, and automatic class selection routines

Activating SMS
Identify the functions eligible for exploitation with the installation of DFSMS Data Facility Product (DFSMSdfp) and the activation of SMS
Create SMS control data sets
Code SYS1.PARMLIB operands necessary to bring up SMS
Create a minimal configuration
Activate a configuration

Writing ACS Routines
Identify the purpose of the ACS routines
Develop an understanding of the statements
Differentiate between literals and masks
Describe the read variables available in the ACS routines

Managing Temporary Data Sets
Create/alter storage classes and storage groups
Identify steps to install and use the starter set
Write ACS routines to handle temporary data sets
Activate a system to manage temporary data sets
Code commands to change volume/group SMS status
Issue operator commands to display current status

Exploiting DFSMS
Describe the purpose of the data class
Identify the features that the data class can exploit
Create data sets using the space parameter
Define Virtual Storage Access Method (VSAM) and volume attributes for data class
Identify special data sets and their exploitation through the data class

Managing Permanent Data Sets
Create/alter data classes, storage classes, management classes, and storage groups
Translate current (DFSMShsm) service level agreements to management class parameters
Identify alternatives and concerns for standard naming conventions
Establish the controls for automatic backup of data sets
Establish the controls for automatic volume dump
Write ACS routines to manage permanent data
Create a configuration that manages permanent data sets
Create a new managed data set
Identify function of storage class exit provided by Custom-Built Installation Process Offering (CBIPO) and resulting System Management Facility (SMF) records

Using Naviquest
Create test cases using Naviquest
Perform storage administration tasks in batch
Create online DFSMS reports
Create model commands using Naviquest
Use the COPYFILT macro

Device Preparation and Data Movement
Initialize volumes as system-managed
Move data into/out from system-managed control
Convert volumes to/from system-managed
Move data to utilize new hardware capabilities

Controlling DFSMS
Code commands to change SMS volume/group status
Issue commands to save configurations and use alternate Active Control Data Set (ACDS)
Issue command to use alternate Communication Data Set (COMMDS)
Issue VARY SMS commands
Communicate with the security administrator about storage management requirements

Additional Considerations
Establish a plan for implementing SMS
Locate sources of implementation planning checklists
Identify the tools available to document the current system
Identify multiple site considerations for recovery and exploitation
