Checking The Status Of The Raid System; Displaying A Defective Hard Disk Of A Raid System In The Raid Software - Siemens SIMATIC IPC547E Operating Instructions Manual

7.1.4

Checking the status of the RAID system

By default, the status of the RAID system (RAID 1 or RAID5) is displayed in the Windows
Event Viewer and in a log file of the program. If an error occurs, a hard disk drive can be
synchronized at the operating system level.
Note
It may take a very long time (hours or even days in the case of a high drive load) to
synchronize a new hard disk in the background, depending on its size and on the system
load.
The ("RAID Level 1" or "RAID Level 5") secure system status is only recovered once
synchronization has been successfully completed.
NOTICE
Operator errors on the machine or plant
Data is synchronized if a hard disk drive fails. Depending on the work load of the processor
and hard disks, the system may react with some delay. Execution of keyboard, mouse or
touch screen commands may be briefly delayed in extreme situations. This could result in
operator errors on the machine or plant.
Do not operate safety-critical functions when a hard disk has failed.

Displaying a defective hard disk of a RAID system in the RAID software

Note
Always replace the defective hard disk with a new hard disk of the same type and capacity.
Replace a faulty hard disk with a new hard disk in order to return to a secure RAID1 state
after an error.
The RAID software indicates the following:
● A defective hard disk
● Details of the functioning hard disk:
SIMATIC IPC547E
Operating Instructions, 09/2013, A5E32317120-AA
The functioning hard disk is indicated by BIOS with its port number or by the RAID
software with its device port number.
The following figure shows the corresponding window in the RAID software with a RAID1
system.
