  5. Select a pair and click An icon showing the letter i to open the SRDF pair list properties panel.

    A graphic displaying the replication configuration is displayed. It shows the following items:

    • Containers representing the R1 and R2 volumes. The color of the container indicates the status of the container:
      • An icon of a blue cylinder with the text "I/O" Read write enabled
      • An icon of a blue cylinder with no text Write disabled
      • An icon of a yellow cylinder with a question mark Connectivity lost
    • An arrow indicating the direction of I/O
    • A central icon and label that indicates the state of the replication pair.
      • An icon of a green circle with a tick symbol Synchronized, Consistent, ActiveActive, ActiveBias
      • An icon of a blue circle with two arrow symbols forming a circle Synchronization in progress
      • An icon of a yellow circle with a pause symbo Suspended, Split, Failed Over
      • An icon of a yellow circle with an exclamation symbol Unknown
      • An icon of a red square with an X symbol Partitioned, Transmit Idle
