Expansion board problems
System requests recovery method during expansion board replacement
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 or
passwords results in loss of access to all encrypted data.
Be sure to enable BitLocker™ after the installation is complete.
For information on BitLocker™, see BitLocker™ for Servers on the Microsoft website
(http://www.microsoft.com
).
