3.5.3 Configuring Physical Arrays and Logical Drives

This subsection provides instructions for using the Easy Configuration, New
Configuration, and View/Add Configuration to configure arrays and logical
drives.
LSI Logic recommends using drives with the same capacity in a specific array.
If you use drives with different capacities in an array, the CU treats all these
drives as if they have the capacity of the smallest drive.
The number of physical drives in a specific array determines the possible RAID
levels that you can implement with the array. RAID 0 requires one to four
physical drives, RAID 1 requires two physical drives, and RAID 10 requires
four physical drives.
3.5.3.1 Physical Drive Parameters
You can change the write policy and read policy in the physical drives, but not
the logical drives. You have to reboot for the changes to the write and read
policies to take effect.
