HI,  If you are making a concat meta, keeping the existing hyper (data) as meta head then there will be no impact to the existing data.  the subsequent devices (other than head) will not preserve data (possible data integrity issue).  refer to the array cli guide for more information.  regards, Saurabh
Hi Everyone,  I want to grow my simple device (hyper) but for expansion device should be a Meta device.  I can make my hyper as meta head and create a Meta.(Concat) But, is it recommended, will there be any impact on data integrity of existing data on hyper?  Thanks Abdul Quadir
Hyper to Meta ?
