Deleting consistency groups (Delete CT Group)
A consistency group can be deleted only from the MCU and only if the MCU does not contain
P-VOLs still assigned to the group. Deleting a consistency group from an MCU does not affect
consistency groups registered at other MCUs. The RCU automatically deletes a consistency group
when the last volume pair in the group is deleted.
Use the Delete CT Group command to delete the selected group from the current MCU.

Connect to the MCU.
2.
From the Consistency Group tree, click a consistency group mode that includes the consistency
group to be deleted.
3.
From the Consistency Group list, click the consistency groups to be deleted. Select more than
one consistency group with MCU in the This CU column.
4.
Right-click, click CT Group Operation, and click Delete CT Group. The list changes to the
Consistency Group Settings Parameter list. If the Delete CT Group command is not enabled,
the selected group still contains P-VOLs in this MCU.
NOTE:
After being set, options can be modified and canceled (see
and deleting consistency groups” (page 88)
).

parameters for the connected disk array. Async options apply to the entire physical control unit,
including all XP Continuous Access P-VOLs and S-VOLs behind the control unit.
