The drive is operating normally, and it has been selected by a management application. A predictive failure alert has been received for this drive. Replace the drive as soon as possible. The drive is online, but it is not active currently. Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. The drive is part of an array that is undergoing capacity expansion or stripe migration, but a predictive failure alert has been received for this drive. To minimize the risk of data loss, do not replace the drive until the expansion or migration is complete. Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. The drive is rebuilding, erasing, or it is part of an array that is undergoing capacity expansion or stripe migration. The drive is active, but a predictive failure alert has been received for this drive. Replace the drive as soon as possible. The drive is active, and it is operating normally. A critical fault condition has been identified for this drive, and the controller has placed it offline. Replace the drive as soon as possible. A predictive failure alert has been received for this drive. Replace the drive as soon as possible. The drive is offline, a spare, or not configured as part of an array. Server updates with an HP Trusted Platform Module and BitLocker™ enabled When a TPM is installed and enabled in RBSU, and when the Microsoft® Windows® BitLocker™ Drive Encryption feature is enabled, always disable BitLocker™ before performing any of the following procedures: • Restarting the computer for maintenance without a PIN or startup key • Updating firmware (on page 81) • Upgrading critical early boot components • Upgrading the system board to replace or remove the TPM • Disabling or clearing the TPM Common problem resolution 20
