Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

When consistency is enabled at the SRDF group name level, the SRDF daemon monitors the SRDF groups separately.

If a concurrent R1 device is unable to propagate its data to one of its remote R2 partners, the daemon suspends the SRDF links for only the group representing that R2 mirror.

Restrictions

• If the two mirrors of the concurrent R1 devices in the composite group are operating in different modes (one mirror in synchronous mode and the other mirror in asynchronous mode), SRDF consistency protection cannot be enabled at the composite group level.

  You must individually enable each group representing the device mirrors by its group name.

• The following table lists the combinations of consistency protection modes allowed for the mirrors of a concurrent relationship.
