Description

Beginning with ONTAP 9.0, FlexArray Virtualization (V-Series) includes resiliency enhancements to reliably handle disruptions caused by back-end path failures, for example, link and switch failures.
The resiliency enhancements include the following:

  • Consistent I/O failover timing in case of path failures
  • Temporary suspension of I/O for a tunable period of time in case of all-path fail conditions
  • Automatic path quiescence in case of intermittent path failures
