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.

Note
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.
Querying the information
The information query is divided into three steps:
Step 1 Information about the existing RAID controllers
Here, both the number and the IDs of the existing RAID controllers are
displayed.
Step 2 Information about the existing RAID volumes
The numbers of existing volumes and hard disks are listed.
Step 3 Status of the existing RAID volumes
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.

Note
A set is the combination of hard disks to form a RAID system. This is
described as a volume in the operating system.
