The following table lists the ShadowImage for Mainframe pair operations that are supported by Business Continuity Manager and IBM^® PPRC.

Pair operation	Option	BCM	IBM^® PPRC
Pair operation	Option	BCM	TSO command	ICKDSF command
Change system options	No options	none	none	none
Create pair	No options	YKMAKE	CESTPAIR	PPRCOPY ESTPAIR
	MU number	none	none	none
	Copy pace	YES²	none¹	none¹
	Steady Split	none	CESTPAIR	PPRCOPY ESTPAIR
	Quick Split	none	none	none
	MSGREQ	none	CESTPAIR	PPRCOPY ESTPAIR
	ONLINSEC	YKMAKE	CESTPAIR	PPRCOPY ESTPAIR
	NOCOPY	YES⁴	none⁵	none⁵
Split pair	No options	YKSUSPND	CSUSPEND	PPRCOPY SUSPEND
	Copy pace	none	none	none⁶
	Steady Split	YKSUSPND	CSUSPEND	PPRCOPY SUSPEND
	Quick Split	YKSUSPND	CSUSPEND	PPRCOPY SUSPEND³
Resynchronize pair	No options	YKRESYNC	CESTPAIR	PPRCOPY ESTPAIR
	Copy pace	YKRESYNC²	none¹	none¹
	Normal Copy	YKRESYNC	CESTPAIR	PPRCOPY ESTPAIR
	Quick Resync	YKRESYNC	CESTPAIR	PPRCOPY ESTPAIR
	Reverse Copy	YKRESYNC	CESTPAIR	PPRCOPY ESTPAIR
	Quick Restore	YKRESYNC	CESTPAIR	PPRCOPY ESTPAIR
	ONLINSEC	YKRESYNC	CESTPAIR	PPRCOPY ESTPAIR
Suspend pair	No options	none	none	none
Delete pair	No options	YKDELETE	CDELPAIR	PPRCOPY DELPAIR
Notes: The system uses Medium speed regardless of what you specify. Normal is the default. If you do not specify an option, the system uses Quick Split. Specify this option only when you can ensure that the contents of the P-VOL and the S-VOL are the same. Even if you specify NOCOPY, the system uses the same action as when COPY is specified. Operates at a speed specified when the pair is created or resynchronized regardless of what you specify.

The following table lists the ShadowImage for Mainframe consistency group (CTG) operations that are supported by Business Continuity Manager and IBM^® PPRC.

CTG action	System option	BCM	IBM^® PPRC
CTG action	System option	BCM	TSO command	ICKDSF command
Assign pairs to a CTG	No options	YKMAKE	CESTPAIR	PPRCOPY ESTPAIR
	MU number	none	none	none
	Copy pace	YKMAKE¹	none²	none²
	User specifies the CTG ID	YKMAKE	CESTPAIR	PPRCOPY ESTPAIR
	System allocates the CTG ID	none	none	none
ATTIME Suspend	No options	YKSUSPND	none	none
	Steady Split	YKSUSPND	none	none
	Quick Split	YKSUSPND	none	none
	(If you share SIz volumes with UR) Steady Split	YKSUSPND	none	none
	(If you share SIz volumes with UR) Quick Split	YKSUSPND	none	none
Cancel ATTIME Suspend	No options	YKSUSPND	none	NO
CTG pair-split (undefined split time)	No options	YKSUSPND	CSUSPEND	PPRCOPY SUSPEND
	Copy pace	none	none²	none²
	Steady Split	YKSUSPND	none	none
	Quick Split	YKSUSPND	none	none
	(If you share SI volumes with UR) Steady Split	none	none	none
	(If you share SI volumes with UR) Quick Split	none	none	none
Resynchronize pairs	No options	YKRESYNC	CESTPAIR	PPRCOPY ES2TPAIR
	Copy pace	YKRESYNC¹	none^{2, 4}	none^{2, 4}
	Normal Copy	YKRESYNC	none	none
	Quick Resync	YKRESYNC	none	none
	Reverse Copy	YKRESYNC	none	none
	Quick Restore	YKRESYNC	none	none
	ONLINSEC	YKRESYNC	CESTPAIR	PPRCOPY ES2TPAIR
Delete pairs	No options	YKDELETE⁴	CDELPAIR	PPRCOPY DELPAIR
Notes: Values: Normal is the default. Medium speed is used regardless of what you specify. You must use a CCI pair group to run the command for the CTG. Operates at a speed specified when the pair is created or resynchronized regardless of what you specify.
