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.
Replacing a faulty drive in a RAID array
Replace faulty RAID drives with a new drive in order to recover secure RAID1 state. The
RAID software reports the faulty drive and returns details of the operable hard drive.
The functioning hard drive is indicated in BIOS by its port number, or by the RAID software
by its device port number.
