closing the software
Warning
Warning
i
Note
Before the Industrial PC is switched off, software that is running
must be properly closed. Otherwise it is possible that data on the
hard disk is lost.
Switch off all parts of the equipment, then uncouple the fieldbus!
Before opening the PC housing, for example to exchange a hard disk, all
system parts must be switched off first and the Industrial PC must then be
uncoupled from the system.
Pulling out the fieldbus connection plug uncouples the PC (optional).
System components that have been switched off must be secured against
being switched on again.
Do not exchange any parts when under power!
When components are being fitted or removed, the supply voltage must be
switched off.
Fitting work on the Industrial PC can result in damage:
• If metal objects such as screws or tools fall onto operating circuit
boards.
• If connecting cables internal to the PC are removed or inserted
during operation.
• If plug-in cards are removed or inserted when the PC is switched
on.
Hard disks in hard drive caddies can also be exchanged whilst the
Industrial PC is in operation.

RAID system
(Redundant Array of
Independent Drives)

Note
RAID level
RAID 1
RAID overview
A RAID system (Redundant Array of Independent Drives) serves to
organize several physical hard disks in a computer into one logical drive
(array).
The essential aim of RAID systems is to support error tolerance and to
improve the performance of the memory sub-system.
From the point of view of the user or an application program, there is no
distinction between a logical RAID drive and a single hard disk.
RAID level
The RAID level defines how the data within the volume that encompasses
the hard disks in the array is formatted. The Intel(R) Matrix Storage
Manager supports RAID Level 1 (mirroring) amongst others.
RAID 1 (mirroring)
The RAID 1 level combines two or more hard disks so that all data is
written simultaneously to all array members of the RAID 1 volume. In other
words: the data is mirrored and distributed across the hard disks in the
RAID 1 volume. This creates real-time redundancy of all of the data on the
first drive.
Configuration
Due to the increased protection against failure, RAID 1 is normally used for
storing critical data. Besides complete data redundancy, a further
advantage is the increased reading transmission rate.
Configuration at delivery state
Industrial PCs with the CB1051 motherboard, which are delivered with
more than one hard disk (HDD) are equipped with the SATA RAID system
as standard. Two of the hard disks are then combined logically to make a
RAID 1 drive.
The hard disks can be permanently installed inside the computer or also
accessible from outside via hard drive caddies.

Status information
Status information
RAID status
The configuration of the system can be accomplished both in BIOS and
under Windows. Furthermore it is possible to recall the status of the system
in TwinCAT.
Status information from BIOS
Display during normal operation
The first possibility to obtain information about the RAID status is during
the BIOS boot process. The second boot screen shows a summary of the
RAID status:
Configuration Utility
In this screen, the Configuration Utility can be opened with Ctrl I:
Beckhoff onboard SATA-RAID 5
Status information
Display after the failure of a hard disk
Failure of a hard disk
If the computer is restarted following the failure of a hard disk, the second
boot screen may look like this, for example:
The status of the RAID volume is described here as “Degraded”. The
status of the hard disk on Port 0 can be seen to be okay (green).
If more than 2 SATA hard disks are installed inside the PC and one of the
two hard disks in the RAID volume failes or the hard disk configuration
inside the PC was changed because of other reasons, then at the next
start or reboot of the PC it is required to enter the BIOS Setup. Go to
"Advanced BIOS Features" "Hard Disk Boot Priority" and move the "INTEL
VOLUME0" to the top position by using the cursor down and the picture up
key. Otherway the PC will try to boot from hard disk three or four instead of
booting from the RAID volume.
Configuration Utility
The Configuration Utility does not display any further information:

volume
Boot screen
If the defective hard disk was exchanged (please refer to chapter
Requirements for a replacement hard disk) whilst the Industrial PC was
switched off, or if the hard disk was exchanged under Windows during
operation without starting a rebuild of the RAID volume, the second boot
screen will appear as follows at the next PC start-up:
A hard disk is shown on Port 1 that does not belong to any RAID volume.
The new hard disk can be selected in the Configuration Utility for the
rebuild of the RAID volume (see chapter Selecting a hard disk for the RAID
rebuild).
However, it is also possible, without first opening the Configuration Utility,
to boot Windows, where the hard disk can then also be selected for the
rebuild of the RAID volume (see chapter Selecting a hard disk (drive) for
the RAID rebuild).
Beckhoff onboard SATA-RAID 7
Status information
Status information under Windows
Display during normal operation
Normal operation
Failure of a hard disk
Under Windows the RAID system works in the background, i.e. under the
operating system the user sees a logical drive that is indistinguishable from
a single hard disk. There is no indication that the system is working
properly.
Display after the failure of a hard disk
Following the failure of a hard disk, a message appears in the task bar at
the bottom right at each restart or new logon.
Example: Port 0 and Port 1 are each connected to a hard disk; the two
disks together form a RAID 1 volume. If the data cable is
unplugged from the hard disk on Port 1, the following message
appears:
Storage Console
Warning
Storage Console: Example
Clicking on the message opens the standard view of the Storage Console.
The opening and usage of the Storage Console can under certain
circumstances lead to impairment of real-time capability!
In this example the hard disk on Port 0 (connection 0) is okay (shown in
green).
The extended view of the Storage Console, which contains further
information, can be opened via the View menu:

Requirements for a replacement hard disk
In an ideal case, a replacement hard disk is brand new and must have at
least the same storage capacity as the drive which it is to replace.
i
i
Note
Note
If no brand new hard disk is available, the following points must be
observed:
• All data that was stored on a drive before it was used as a replacement
hard disk will be lost as a result of its use as a replacement hard disk.
• Information about the RAID system is stored on every hard disk that
belongs to a RAID system. Therefore a hard disk from the RAID
system of a different computer must be “reset” with respect to RAID
before it can be used as a replacement hard disk.
Resetting a replacement hard disk for the RAID rebuild
The resetting of a replacement hard disk is only necessary if it comes from
a RAID system.
Hard disks can be reset in the Configuration Utility during the BIOS boot
process or under Windows.
It is not necessary to reset a replacement hard disk with the PC, in which it
will be used later. For example the disk can also be reset in the PC it
comes from.
The hard disks can be identified best via their port numbers.
The hard disks of the PCs with or without hard drive caddies are labeled
with the port numbers.
For each hard disk the port is shown in the Configuration Utility and in the
Storage Console.

Resetting a replacement hard disk with the
Storage Console
The opening and usage of the Storage Console can under certain
circumstances lead to impairment of real-time capability!
With the Storage Console the according volume is reset, not the hard disk.
After the volume that has to be reset was identified in the extended view of
the Storage Console via the port of the according hard disk, Delete Volume
has to be selected from the context menu of the according volume:

Rebuilding the RAID system
RAID rebuild under BIOS
Selecting a hard disk for the RAID rebuild
If the Configuration Utility is opened, there is a possibility to specify a newly
connected hard disk (theoretically, more than one new hard disk may have
been connected) for rebuilding the RAID volume.
If more than 2 SATA hard disks are installed inside the PC and one of the
two hard disks in the RAID volume failes or the hard disk configuration
inside the PC was changed because of other reasons, then at the next
start or reboot of the PC it is required to enter the BIOS Setup. Go to
"Advanced BIOS Features" "Hard Disk Boot Priority" and move the "INTEL
VOLUME0" to the top position by using the cursor down and the picture up
key. Otherway the PC will try to boot from hard disk three or four instead of
booting from the RAID volume.
Configuration Utility
In the example, only the defective hard disk was replaced:
After a hard disk has been selected, the Configuration Utility shows the
new hard disk as a member of the RAID volume with the ID 0. The status
of the RAID volume was changed from “Degraded” to “Rebuild”.
At the lower edge of the screen there is a notice that the rebuild process
will first be started under the operating system.

RAID diagnosis under TwinCAT
RAID diagnosis under TwinCAT
The RAID system works in the background, i.e. under the operating system
the user sees a logical drive that is indistinguishable from a single hard
disk. The configuration of the system can be accomplished both in BIOS
and under Windows. Furthermore it is possible to check the status of the
system in TwinCAT.
TwinCAT RAID diagnosis
The Storage Console must be installed in order to be able to use TwinCAT
RAID diagnosis!
As an alternative to the user interface of the Intel Matrix Storage Console,
the TwinCAT RAID diagnosis offers a real-time-capable option for querying
the status of the RAID system.
In order to change the RAID system, however, the Storage Console must
still be used.
The information is queried by a standardized interface of the RAID driver.
i
Note
Querying the information
Step 1 Information about the existing RAID controllers
The information query is divided into three steps:
Here, both the number and the IDs of the existing RAID controllers are
displayed.
Step 2 Information about the existing RAID volumes
Step 3 Status of the existing RAID volumes
i
Note
The numbers of existing volumes and hard disks are listed.
The status is queried in each case for a single controller ID and a single set
number:
• RAID type,
• status of the RAID volume (OK, degraded, rebuilding, failed),
• number of hard disks that make up the set,
• serial numbers of the hard disks that make up the set and
• the hardware ports on the motherboard to which the hard disks making
up the set are connected. In the event of a failure it can hence be
determined which hard disk is OK or which one must be replaced. In
the case of delivery with hard drive caddies, these are each identified
by a label showing the port number.
A set is the combination of hard disks to form a RAID system. This is
described as a volume in the operating system.
