12. WHAT TO DO IN THE EVENT OF A DISK DRIVE FAILURE

The G-Tech RAID controller continually monitors the health of each of
the disk drives in G-SPEED eS PRO. In the event of a disk failure, an
audible alarm will sound. The web GUI will also report the failed drive
and its physical position.
NOTE: If G-SPEED eS PRO was configured in a protected
RAID mode (RAID 1, 3, or 5), a drive failure does not result in
data loss. However, the array is now in an unprotected state
and the failed drive should be replaced as soon as possible to
avoid data loss.
NOTE: If G-SPEED eS PRO was configured in RAID 6 mode,
up to two drives can fail with no loss of data. Replace any
failed drive as soon as possible.
Follow the steps below to identify and replace a failed drive.
1. Launch the web GUI.
2. Mute the alarm by clicking on the <Beeper Mute> button.
The GUI will display information like that shown below. An
exclamation mark on the G-SPEED eS PRO icon indicates that
the "Status" of the array is Critical. The lower portion of the GUI
indicates which drive in which G-SPEED eS PRO unit has failed.
In this example there are two G-SPEED eS PRO units
connected to the G-Tech RAID controller. Drive 7 of the
G-SPEED eS PRO connected to Port 2 of the G-Tech
RAID controller has failed.
