PowerMax Family Local and Remote Replication Concepts

What does an update operation do in SRDF on PowerMax arrays?

  • A A process to retain the data on the target R2 side.
  • B A process used to return to the original production site after a failover event.
  • C A process that initiates an incremental copy from the target R2 to the source R1.
  • D A process that allows separate hosts to access the same data independently.
Explanation

An SRDF update operation updates the source R1 side with changes made on the target R2 side while the R2 remains available to its local hosts. It therefore initiates an incremental copy from R2 to R1.
