Moving generation data sets to SMS-managed volumes

An SMS-managed generation data set (GDS) can be in one of three states:

ACTIVE
DEFERRED
ROLLED-OFF

When copying a GDS to an SMS-managed volume and the data set is not preallocated, DFSMSdss allocates the target GDS as follows:

If DELETE is specified and RENAMEUNCONDITIONAL is not specified, the target GDS is allocated with the same state as the source GDS.
If the TGTGDS keyword is specified, the appropriate status is assigned to the data set. The requested target status must not violate rules of the generation data group.
When the source is an SMS-managed GDS and the target has the same name (that is, DELETE without RENAME), the target status is the same as the source status.
When the source is a non-SMS-managed GDS and the target has the same name (that is, DELETE without RENAMEUNCONDITIONAL), the default target status is ACTIVE when the source is cataloged. When the source is not cataloged, the default target status is DEFERRED.
In all other cases, the default target status is DEFERRED.
You can use the TGTGDS keyword to alter the target status except when the source is an SMS-managed GDS and the target has the same name.

Table 1 describes the default situation for DFSMSdss to allocate the SMS-managed GDG data set (MOVE refers to COPY command with the DELETE keyword specified):

Table 1. Default Situation for DFSMSdss to Allocate the SMS-Managed GDG Data Set
Target Environment	Source Environment	Source Status	DFSMSdss Function	TGTGDS Default
SMS	Non-SMS	Cataloged	COPY	DEFERRED
		Cataloged	MOVE	ACTIVE
		Not Cataloged	COPY	DEFERRED
		Not Cataloged	MOVE	DEFERRED
	SMS	ACTIVE	COPY	DEFERRED
		ACTIVE	MOVE	ACTIVE
		DEFERRED	COPY	DEFERRED
		DEFERRED	MOVE	DEFERRED
		ROLLED-OFF	COPY	DEFERRED
		ROLLED-OFF	MOVE	ROLLED-OFF

If the data set is preallocated, the state of the target GDS is not altered.
