NEC Express5800 Series User Manual page 54

At the completion of the rebuild, the logical drive returns to the normal state.
NOTES:
Manual start of rebuild
The rebuild process for a logical drive in the critical state can be manually started.
At the end of rebuild, always check the event log to
see if any error occurs during rebuild. When a media
error occurs, a message indicating the occurrence of
the error appears before the message indicating that
the rebuild has terminated normally.
The interval from the removal of the defected HDD to
the installation of a substitute HDD should be 90 sec
or longer.
If the Buzzer Status is set to "Enable" in the controller
setup, the buzzer beeps with the logical drive being in
the critical or offline status or during rebuild. To
switch the buzzer on/off, use the Buzzer Status radio
button in the Settings tab of the controller. The buzzer
sound stops when the logical drive becomes
Functional. The buzzer sound may not stop depending
on the type of your system. In this case, set the option
to Disable and restart the system to stop the buzzer
sound.
The buzzer feature cannot be used if the sound
module is not installed.
