Performing a quick configuration
This section provides quick installation steps for users that are familiar
with configuration utilities and tools. Refer to "Configuring arrays and
logical drives" on page 106 for detailed configuration instructions. To
ensure best performance, select the optimal RAID level for the logical
drive you create.
Perform the following steps to configure arrays and logical drives using
the Configuration Utility (CU):
1
Boot the system.
2
Start the CU by pressing <Ctrl><E>.
3
Select a configuration method.
4
Create arrays using the available physical drives.
5
Define the logical drive(s) using the space in the arrays.
