Points of caution while using SnapMirror

While using SnapMirror, you need to exercise adequate caution on several points, including the use of Snapshot copies, the use of SnapMirror commands, and the use of SnapMirror destination volumes.

Note:
  • If Flash Cache is used in SnapMirror source and destination, during an application failover at the disaster recovery site, then there will be latency during the read operations on the destination as compared to the source, even though the destination system has the same Flash configuration as the source.
  • If Flash Cache is deployed with synchronous SnapMirror, then there might be latency during the read operations on the destination storage system.
