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.
