Basic software procedures
5.2.14 Resuming BitLocker functionality
If BitLocker Drive Encryption has been suspended for maintenance purposes
(see section "Suspending BitLocker functionality" on page 67), it has to be re-
enabled to complete the service task.
I If BitLocker Drive Encryption has been suspended prior to replacing
components you won't be asked for a recovery key when rebooting the
server after the maintenance task. However, if BitLocker functionality has
not been suspended, Windows will enter recovery mode and ask you to
input recovery key for further booting.
Ê In this case, ask the system administrator to enter the recovery key in
order to boot the operating system.
Ê Ask the system administrator to enable the previously suspended BitLocker-
protection on the system volume, using the BitLocker Drive Encryption
control panel item:
Ê Click Start - Control Panel - System and Security - BitLocker Drive
Encryption to open the BitLocker Drive Encryption.
Ê Select the system volume, and click Resume Protection.
I For more information on how to resume BitLocker drive encryption, see
the Microsoft TechNet library at

For more information, see the Fujitsu web pages.
5.2.15 Performing a RAID array rebuild
After replacing an HDD that has been combined into a RAID array, RAID rebuild
will be performed completely unattended as a background process.
Ê Ensure that the RAID array rebuild has started normally. Wait until the
progress bar has reached at least one percent.
Ê Inform the customer about the remaining rebuild time, based on the
displayed duration estimate.
