Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Before you can dynamically modify SRDF consistency groups, you must create a staging area that mirrors the configuration of the CG. The staging area consists of:

• SRDF groups containing the device pairs to be added to a consistency group (symcg modify -add operations),
• SRDF groups for receiving the device pairs removed from a consistency group (symcg modify -remove operations).
• The SRDF groups in the staging area must be established between the same arrays as the SRDF groups in the consistency group.

  For concurrent CGs, the SRDF groups in the staging area must be established among three arrays.
