When possible, I would also make sure that the drive and any HBA that it may be attached to have the latest firmware versions to ensure they can understand the change in sector size after it's performed and don't have any other compatibility issues. Data is not guaranteed to be accessible in the same way after changing the sector size and other things already written to disk may use checksums based on individual sector sizes which would no longer work properly once changed (if the original data was still accessible). Also, make sure that low-level configuration commands such as these are performed prior to writing any partition information on the disk. The best advice I can give for configuring any new product before integration into a system is to do it from a Live OS (LiveCD or LiveUSB) to reduce the chance of an installed OS from trying to interact with the drive during any of the configuration process.
