9. Click the appropriate Array tab.
10. Select a RAID level from the drop-down list. (For more information, see
Chapter 3, "Understanding RAID technology" on page 21.)
Notes:
a. Create only one logical drive for each array.
b. A logical drive cannot exceed 2048 GB.
c. Typically, the first logical drive defined on the first ServeRAID controller
found by system BIOS during startup will be your startup (boot) drive.
Attention: Before assigning a logical drive RAID level-5E, consider the following. If a
physical drive fails during a post-failover resynchronization, the logical drive will enter the
blocked state. Data might be lost or damaged.
11. Repeat steps 9 and 10 for each additional array you want to configure.
12. Click Next. The "Configuration summary" window opens.
