    Hi Kanstantsin,

    With SFW you can migrate to a new lun by using the mirror process.  You can also drag and drop the volume in "Disk View" to the new subdisk.

     

    You didn't mention what version of SFW that you are using. If you are using 5.1 make sure that you are at SP2 with CP21. 

     

    Thank you,

    Wally

It sounds as if the shrinking at storage level recreates/formats the lun as if it is new.

Have you checked with your Storage Vendor that shrinking can be performed on online luns/volumes?
