This is why we asked these questions.
 
Why are you going to ontap 8.1.4, and not a higher version.
 
If you have cdot, you should be looking to go to 9.1p1
 
If you have 7-mode you need to go to 8.2.4  - latest P release.
 
Also, all the disk firmware is easy, Just follow the steps from the download site for the disk firmware,  I recommend using the all.zip package
