Create A New Host Drive - Intel SRCU31A - Server RAID U3-1A Controller User Manual

Create a New Host Drive

Double click on the new host drive icon. Only host drives are "visible" to the operating system.
The structure of the host drives is not known to the operating system. The operating system does
not recognize that a given host drive consists of a number of hard disk drives forming a disk array.
To the operating system this host drive simply appears as one single hard disk drive with the
capacity of the disk array. This complete transparency represents the easiest way to operate disk
arrays under any operating system. Neither operating system nor the computer need to be involved
in the administration of these complex disk array configurations. To create a new host drive, you
need one or more physical drives which are not yet part of another host drive. After double
clicking on the new host drive icon a new window opens. See Figure 88.
On the left side of the window are the available physical drives. Under the drives you can see their
physical coordinates (channel/ID/LUN), the manufacturer and the vendor-unique name. On the
right side you see a list of all possible host drive types which can be configured. When there is no
physical drive selected in the left box, all possibilities are disabled. While selecting physical drives
for the new host drive, more attributes become selectable.
You can select a single physical drive by clicking on it. If you want to select more than one
physical drive, simply draw a frame around the physical drives, or press the <Ctrl> key and then
click on all the physical drives you want to combine to a new array.
When you have finished the selection of the physical drives, choose the type of host drive you want
to create and click on OK.
If the selected host drive uses data striping (RAID 0, 4, 5, or 10) you can change the default striping
size. If you have selected a configuration with hot fix (terms_hot_fix) drives, you can choose
between a private hot fix drive or a pool hot fix drive. After the host drive was created, you can
partition and format the host drive with the corresponding operating system utility.
