can not restore flashcopy snapshot - ibm.spectrum_virtualize.ibm_svc_manage_flashcopy

[scheurer13]

SUMMARY

I'm trying to create a Flashcopy mapping using the ibm.spectrum_virtualize.ibm_svc_manage_flashcopy module. Goal is to clone the existing snapshot to the original. So target already exists.

@scheurer13 To use this functionality, target volume must not pre-exist. Please try with a non-existent target volume.

[scheurer13]

Hello @Shilpi-J , thanks for answer. Target to non pre-exist volumes works. But i think on restore/fallback we have to do a step more and need many free space. On SVC/svctask it is also possible to copy back the target to the source without stop the snapshot.

I´m also missing the "-incremental" feature on ibm_svc_manage_flashcopy. Should i open a pull request for this?

[Shilpi-J]

@scheurer13 The functionality was designed to make it easier for the user and automate the process. I will check if we can do any changes regarding your feedback here. Please go ahead and raise the PR for "incremental", no issues here. Thanks

I believe you are trying to create a reverse flashcopy to revert the fc source volumes back to their original state.

I'm writing some FC roles and I also want to be able to use this module to create a reverse flashcopy where the target already exists as the source for an existing flashcopy operation.
