i try to downgrade ontap from 8.2.1 to 8.1.4, but i forget to input the command: revert_to 8.1.

so i fail to boot the system, and hang on.

can any one give some suggestion?

As we told you in the previous thread what we suggested you to do... Netboot, but this seems like a new system, why aren't you calling support? That's why you pay all that money....

I already use netboot to reinitiate the system, and it works fine.
