Displaying A Defective Hard Disk Of A Raid System In The Raid Software - Siemens SIMATIC Series Operating Instructions Manual

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.

Always replace the defective hard disk with a new hard disk of the same type and capacity.
If an error is detected the defective hard disk must be replaced with a new hard disk to return
to a secure RAID status after an error.
The RAID software indicates the following:
● A defective hard disk
● Details of the functioning hard disk:
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.
