GigaRAID (IT8212) ATA RAID Controller USER'S MANUAL
You can use arrow keys ↑ and ↓ to highlight the drive you want to assign to the
disk array and change the status of Assignments to "Y" by pressing the "space" bar
key.
For the meanings of "Array Mode", "Drive No" and "Status", please refer to Define
RAID Menu on page 22. The location of the hard drive is shown at the column
"Channel ID". "Pri" represents the primary channel and "Sec" represents the
secondary channel. D0 represents a master hard drive while D1 represents a slave
hard drive. Column "Drive Name" shows the model name of the hard drive. Column
"Size" shows the capacity of each hard drive. When a symbol is shown before the
size, the capacity unit is gigabyte.
When you press "Ctrl-Y" keys to save your change, Setup Utility will check if the
setting is legal. If not, an error message will pop up to show you what the error is and
you have to correct the setting. Limitations are shown as below.
Stripe (RAID 0): There isn't any specific limitation.
Mirror (RAID 1): Two hard drives that form a RAID 1 array have to be attached as the
same master or slave hard disks. For example, primary channel (Pri) master drive
(D0) and secondary channel (Sec) master drive (D0) can form a mirror array; primary
channel (Pri) slave drive (D1) and secondary channel (Sec) slave drive (D1) can form
a mirror array; but primary channel master drive and primary channel slave drive
cannot form a mirror array.
Stripe + Mirror (RAID 0+1): A RAID 0+1 array has to be formed by four hard drives.
