If you shut down and restart the system without installing a functioning new hard disk,
"unused" is displayed for the corresponding SATA port. In this case, you will need to shut
down the system again and boot with the functioning hard disk. The new hard disk is then
assigned to a SATA port and can be included in the RAID system. The "Rebuild to another
Disk" command initiates synchronization of the RAID1 system.
A defective drive is still displayed during the rebuilding process. This drive disappears from
the display when the rebuild process is complete.
4.3.4.2
RAID5 system
This is a RAID5 system configuration (striping with parity). This means that if there is a
defective hard disk or there are cable problems, the system can continue to operate in one
channel achieving a high degree of system availability.
Note
You will find information about the Intel RAID controller in the RAID documentation in the
"Drivers\RAID\Intel" directory on the "Documentation and Drivers" DVD that ships with the
product.
