Snapmirror Release trought API (SLM)

lcoppitelli

Hi,

 

I'm tring to automate the deletion of a Volume and the related snapmirror relationship trough ontap2.0 apis in SLM.

 

i'm able to delete the snapmirror relationship on the destination volume, but usually, doing so from the GUI, you have the options to also release the snapmirror rerlationship on the source volume:

While working on ontap APIs, there dosen't seem to be any snapmirror-release related call, therefore i'm unable to delete the source voume since it gives me an error stating that the volume is part of an un-released snapmirror relationship.

 

any idea on how to release a SM relationship?

Hi Lorenzo,

 

SLM internally performs the snapmirror release operation (in addition to performing snapmirror delete) when you invoke DELETE /ontap/snap-mirrors/{snap-mirror-key} API.

So, instead of deleting the snap-mirror out of band using GUI, we recommend you to use the SLM API mentioned above.

 

For the current source volume which is tied to an unreleased but deleted snapmirror, you will need to use ONTAP CLI to release the snapmirror.

Please let us know if you need further details on this.

Sen.

Here is the error i get after trying to DELETE the volume:

    "records": [

      }
    ]
  }
}
