Validating an entire SCDS

For its contents to become the active storage management policy for an installation, an SCDS must be valid. Activating an SCDS validates its contents and copies them into the ACDS identified by IGDSMSxx. If the SCDS is not valid, activation fails.

To define a valid minimal SMS configuration, the configuration must contain:

A fully defined base configuration
A storage class definition
A pool storage group containing at least one volume, or a VIO, object, or tape storage group
A storage class ACS routine
A storage group ACS routine

See z/OS DFSMS Implementing System-Managed Storage for more information on defining a minimal SMS configuration.

Before you begin: Display the CDS Application Selection panel (select option 8 from the ISMF Primary Option Menu for Storage Administrators.)

Perform the following steps to validate an entire SCDS.

On the command line of the CDS Application Selection panel, type the VALIDATE command. This displays the Validate ACS Routines or Entire SCDS panel.

Supply values on the Validate ACS Routines or Entire SCDS panel:
SCDS Name

Identifies the data set you want to validate. It is a required field that is primed with the last used value. The default is blank.

ACS Routine Type

Type an * in this field, because you are validating an entire SCDS.

Listing Data Set

Identifies the name of a sequential data set to contain the results of the validation. If you specify a data set that already exists, the validation process replaces the existing data set contents with the results of the validation. If you specify a nonexistent data set, the validation process allocates space for it. If you leave this field blank, which is the default, you receive the result of the validation, but you do not get a listing.

Press Enter to perform the validation. See Validation results for more information.
