Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Control operations on SRDF devices, including:

• Establishes (mirrors) an SRDF pair by initiating a data copy from the source (R1) side to the target (R2) side. This operation can be a full or incremental establish.
• Restores remote mirroring. Initiates a data copy from the target (R2) side to the source (R1) side. This operation can be a full or incremental restore.
• Splits an SRDF pair, which stops mirroring for the SRDF pairs in a device group.
• Fails over and back from the source (R1) side to the target (R2) side, switching data processing to the target (R2) side.
• Updates the source (R1) side after a failover, while the target (R2) side may still be operational to its local host(s).
• Swaps the source (R1) and target (R2) destinations between the target and the source.
• Creates, deletes, or swaps dynamic SRDF device pairs.
• Performs dynamic SRDF group controls to add, modify, and remove dynamic groups.
• Enables link domino locally or remotely when creating dynamic groups.
• Enables auto link recovery locally or remotely when creating dynamic groups.
• Enables/disables consistency for SRDF/A capable devices operating in asynchronous mode that are managed by a device group or file.

Uses concurrent SRDF/Synchronous and SRDF/Asynchronous links to replicate source data synchronously to a nearby regional site and asynchronously to a distant remote site.
