 In general, if you are cloning a UFS based system, then be very careful that your disklabel is going to give you enough space for the **/** and **/usr** file systems. If you are using AdvFS make sure that the total slices you set aside can be used to add up to the sizes you need (ie.. remember that AdvFS can do concatination, mirroring, and striping between disk/block devices). This is an effort you need to make before you start copying over files, because by then it could be too late to correct a size mismatch and you'll simply find out because the destination file system or file set will fill up before your copy/sync operation completes.  In general, if you are cloning a UFS based system, then be very careful that your disklabel is going to give you enough space for the **/** and **/usr** file systems.

Double check your source and destination device and make sure that your old device name isn't still leftover in a config file somewhere. Most commonly it's the **/etc/fstab** or bad disk-symlinks in **/etc/fdmns**. Also it's also worth perusing **/etc/sysconfigtab** on 5.x for mistakes or old device names.
   - Make sure if you use a new system type that any kernel tuning you do makes sense. Ie.. if you take parameters from a system that has 4GB of RAM and try to use them on a big GS1280 with 64GB of RAM then you are almost certainly going to have some bad tuning in there. Double check your __sysctl__ settings with **sysctl -a**.    - Make sure if you use a new system type that any kernel tuning you do makes sense.
