Commands for Version 1 Operations

Version 1 supports both DFSMSdss commands and PPRC TSO commands to enable you to perform

Version 1 operations from zSeries and S/390 host systems. This user's guide does not provide

complete instructions for using commands from the host system. For detailed information on using

the DFSMSdss and TSO PPRC commands, see the IBM user documentation.

To use the TSO PPRC commands, you must add the command names to the AUTHCMD PARM of

IKJTSOxx that is a member of SYS1.PARMLIB, because of the system is protected by the RACF

Facility. For details, see the IBM user documentation.

The PPRC TSO commands and the DFSMSdss command that are available for Version 1 are:

• PPRC TSO commands

FCESTABL

FCWITHDR

FCQUERY

• DFSMSdss command

COPY FULL

Establishing a Version 1 Relationship

You need to use the FCESTABL command of PPRC TSO or the DFSMSdss command to establish a

Version 1 relationship.

Establishing a Version 1 Relationship Using FCESTABL

You must specify the simplex volume to establish a Version 1 relationship. In addition, when the

SSID boundary is 64-LDEV, the S-VOL and the T-VOL for Version 1 must be established in the same

CU image and SSID.
