DFSMSdfp: Remove SMA fields from the SMS storage group construct IGDSGD and from ISMF panels

Description

Before z/OS V1R13, new SMS storage group constructs were created in DFSMS in support of the z/OSMF DASD Management task. Starting with z/OS V1R13, the DASD Management task has been removed from z/OSMF, and these fields (known as SMA attributes) will be removed from the storage group construct (IGDSGD). The fields have been removed from ISMF panels, Naviquest APIs, and DCOLLECT records.

Table 1 provides more details about this migration action. Use this information to plan your changes to the system.

Table 1. Information about this migration action
Element or feature: DFSMSdfp
When change was introduced: z/OS V1R13 with APAR PM40869 applied. See Software Announcement 211-252 (RFA56143).
Applies to migration from: z/OS V1R13 without APAR PM40869 applied.
Timing: Before installing z/OS V2R2.
Is the migration action required? Yes, if you parse the new attributes in DCOLLECT output or view/update them through NAVIQUEST. IBM might redefine these storage group and DCOLLECT fields in a future release.
Target system hardware requirements: None.
Target system software requirements: None.
Other system (coexistence or fallback) requirements: None.
Restrictions: None.
System impacts: None.
Related IBM Health Checker for z/OS check: None.

Steps to take

Follow these steps:
  1. Look for the following storage group attributes (known as SMA attributes) as defined by the IGDSGD macro.
    • SGDMANTH
    • SGDMASUG
    • SGDMAMAX
    • SGDMAVSZ
    • SGDMAVTC
    • SGDMARSP
    • SGDMAVNM
  2. Identify the following Naviquest functions associated with the SMA attributes identified in step 1:
    • ACBQBAJ2: clist for Define/Alter/Display pool storage group
    • ACBQBAJG: clist for Pool Storage Group Display
    • ACBJBAJ2: Sample JCL for Pool Storage Group to define, alter, and display.
  3. Use the IDCDOUT mapping macro to map the following DCOLLECT fields and remove the references to those fields:
    • DSGFSMA
    • DSGMANTH
    • DSGMASUG
    • DSGMAMAX
    • DSGMAVSZ
    • DSGMAVTC
    • DSGMARSP
    • DSGMAVNM
