Notes

Note

  • The check_mode is supported.

  • Idempotency is not supported for create snapshot operation.

  • There is a delay in reflection of final state of RCG after few update operations on RCG.

  • In 3.6 and above, the replication consistency group will return back to consistent mode on changing to inconsistent mode if consistence barrier arrives. Hence idempotency on setting to inconsistent mode will return changed as true.

  • The modules present in the collection named as ‘dellemc.powerflex’ are built to support the Dell PowerFlex storage platform.
