7.1.4 Checking the status of the RAID system
By default, the status of the RAID system is displayed in the Windows Event Viewer and in a
log file of the program. If an error occurs, a hard disk 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 redundant system state is reached again only after synchronization is completed.
NOTICE
Operator errors on the machine or plant
Data is synchronized if a hard disk 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.
