Comments about faults
NOTICE
Input delay
System load may briefly increase due to synchronization when a hard disk has failed,
depending on processor load and current hard disk activity.
Execution of keyboard and touch screen commands may be briefly delayed in extreme
situations.
Before you replace the defective hard disk, create a backup copy of the system.
Replacing a faulty drive in a RAID array
Replace defective RAID drives with a new drive in order to achieve safe RAID1. The RAID
software reports the faulty drive and returns details of the operable hard drive.
The working disk is displayed by the BIOS with a port number or by the RAID software with a
device port number. To view details about each drive, move the mouse cursor over the drive
and press the right mouse button. A pop-up window is then activated.
Figure 7-3
The functioning drive can be located using the following pictures and tables.
The table and information below apply only to the delivery state of the device, that is if no
changes or expansions were made.
