WFA Return Parameters LUN ID

John_Blackwell — Wed, 04 Jun 2025 12:51:38 GMT

Hello All,

I have created a workflow which creates a volume/lun and maps it to an existing igroup, I want it to return the LUN id used (as I dont specify it), I have played with return parameters section but I cannot find the parameter value.

Hoping I cannot be the first person wanting to do this?

Any help would be much appreciated?

John

Many thanks for this, so I have cloned the certified command for map lun and added the section at the bottom then in the workflow gone to the return parameters tab and added LunId but for some reason it seems to errors with the below, i guess I am doint something wrong?
