Expansion board issues

System requests recovery method during expansion board replacement
Symptom
The system request a recovery method while the expansion board is being replaced on a BitLocker-encrypted
server.
Action
Verify that BitLocker was disabled before replacing the expansion board.
When replacing an expansion board on a BitLocker-encrypted server, always disable BitLocker before
replacing the expansion board. If BitLocker is not disabled, the system requests the recovery method selected
when BitLocker was configured. Failure to provide the correct recovery password(s) will result in the loss of
access to all encrypted data. Once the expansion board is replaced, enable BitLocker.
For more information on BitLocker, see BitLocker for Servers on the Microsoft website.
