4.3.1.2 ISMF for the Storage Administrator

Figure 9 on page 27 shows the ISMF primary option menu displayed for a storage administrator. Options allow lists to be built from volume selection criteria (Storage Group), as well as the Management Class, Data Class, and Storage Class facilities allowing the individual to define, alter, copy, and delete SMS classes, volumes, and data sets. Again, these lists are built from VTOC or catalog information, and tailored in the same way. This panel is selected from the ISPF/PDF primary menu (dependent upon site customization).

4.3.2 DFSMSdss

The Data Set Services (DSS) component is a disk storage management tool. It can be invoked using ISMF. The following sections describe DSS capabilities.

4.3.2.1 Functionality

The DSS component is able to perform a variety of space management functions. Of these, the most common are listed below:

COMPRESS

Compresses partitioned data sets.

CONVERTV

Converts existing volumes to and from SMS management

 

without data movement.

COPY

Performs data set, volume, and track movement, allowing

 

the movement of data from one disk volume to another,

 

including unlike device types.

COPYDUMP

Allows the generation of 1 to 255 copies of DFSMSdss

 

produced dump data. The data to be copied can be tape

 

or disk based, and copies can be written to tape or disk

 

volumes.

DEFRAG

Reduces or eliminates free-space fragmentation on a disk

 

volume.

DUMP

Performs the dumping of disk data to a sequential volume

 

(either tape or disk). The process allows either:
