Astaro Security Gateway 625
Operating Instructions
7. RAID hard disk system
The Astaro Security Gateway 625 is equipped with a RAID system with
two hard disks. A RAID system (redundant array of independent disks)
connects several physical hard disks to one particularly performing logical
drive. This type of hard disk system enhances the transfer rate and data
security. Additionally, a RAID system increases the availability of the security
appliance since a defective hard disk can easily and quickly be exchanged—it
is not necessary to shut down the system.
The RAID system can be monitored via the graphical user interface
WebAdmin. The current status of the RAID system is displayed on the
dashboard in the RAID status section. In addition to that, a corresponding
notification email is sent to the administrator in the event of a defect in a
hard disk.
Important note:
If you need to change a hard disk because of a defect,
remember to remove the defective hard disk from the RAID system,
otherwise the whole security appliance will fail. Please note that the safe
operation of the hardware appliance is only ensured in the long term if both
hard drives are working. Immediately exchange damaged hard drives. Only
use hard disks which you purchased directly from Sophos or from a Sophos
distribution partner. Please remember that any warranty claims are voided
for the appliance if a defect has been caused by the use of hard disks which
are not suited for the system.
Exchanging the hard disk
1. Identify the defective hard disk.
In the event of a hardware defect, the dashboard of the WebAdmin user
interface will display the defective hard disk: e.g., HDD1 (right hard disk).
2. Use the included key to open the hard disk latch.
3. Unlock the hard disk by pushing the latch to the left and pulling the
lever in your direction.
4. Remove the hard disk from the chassis.
5. Now, insert the new hard disk into the chassis.
6. Lock the hard disk by pushing the lever in the direction of the
chassis. Lock the latch at the hard disk.
Important note:
Except for short periods of time (e.g., swapping hard disks),
do not operate the server with an empty hard disk drive. As soon as the
security appliance detects the new hard disk, the existing hard disk is
mirrored to the new hard disk. This process may take 30 minutes or more.
The current status of the RAID system is displayed on the dashboard in the
RAID status section. Prior to and after termination of the saving process, a
corresponding notification email will be sent to the administrator.
