Zeroizing the Sun Crypto Accelerator

4000 Hardware to the Factory State

In some situations, it may become necessary to return a board to failsafe mode,
and clear it of all key material and configuration information. This can only be done
by using the hardware jumper attached to the board.
Note – Youcan use the zeroize command with the vcaadm utility to remove all
key material from a Sun Crypto Accelerator 4000 board. However,the zeroize
command leaves any updated firmware intact. See “Zeroizinga Sun Crypto
Accelerator 4000 Board” on page80. Also refer to the vcadiag online manual pages.
