17. If you have multiple controllers, do the following:
a. Click the ServeRAID controller that you want to configure.
b. From the toolbar, click ( Configure RAID ).
c. Repeat steps 2 on page 39 through 17b for each controller.
18. When you have completed configuring your controllers, you can change certain
controller settings. See “Fine-tuning your configuration” on page 43 for more
information. If you do not want to change any settings, exit from the
ServeRAID Manager program, and remove the CD from the CD-ROM drive.
19. Restart the server.

Note: If you are configuring your startup (boot) ServeRAID controller, you
must install the device driver while installing the operating system.
Creating spanned arrays: If you want to assign RAID level-x0 to an array, you
must create a spanned array. For more information about spanned arrays, see
“Understanding RAID level-x0” on page 30.
Notes:
1. Spanned arrays are supported only by ServeRAID-4 and ServeRAID-5i
controllers.
2. A logical drive cannot exceed 2048 GB.
Complete the following steps to create one or more spanned arrays:
1. If you have not completed steps 1 to 3 in “Using Custom configuration” on
page 38, do so now.
2. Create identical arrays by doing the following:
a. Click the Array tab in the right panel; then, from the list of ready drives,
select the drives you want to move to the array.
b. Click ( Add selected drives ) to add the drives to the array.
c. Repeat steps 2a and 2b for each additional array that you want to configure.
Note: To create a spanned array, the arrays to be spanned must be
identical (that is, they must have the same number of physical
drives).
d. Select the Span arrays check box; then, click Next . The “Create
spanned arrays” window opens.
