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.

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 and z/OS V1R12, both without APAR PM40869 applied.

Timing:

Before installing z/OS V2R1.

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:

Look for the following storage group attributes (known as SMA attributes) as defined by the IGDSGD macro.
- SGDMANTH
- SGDMASUG
- SGDMAMAX
- SGDMAVSZ
- SGDMAVTC
- SGDMARSP
- SGDMAVNM
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.
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
