It's online non disruptive, but just to be aware it will take some time.. The array has to copy all data to BCV do the conversion and stripe back mileage will vary    Sent from my Samsung device
I've just found a procedure to convert a concat meta to a striped meta device using the symconfigure command with the "convert meta" option.  Is this procedure online? or requires some service disruption?  Thanks in advance  Best regards  Richard Rodríguez
