On HPE SSA main screen click on array controller:
In the Smart Array Actions menu choose Configure option:
Click on Create Array button:
This example uses two hard drives but it’s still the same process with a single one.
In RAID level section ensure that RAID 1 (or RAID 0 if it is the only available option) has been chosen, you can leave the remaining parameters in their default values:
Click on Create Logical Drive button to create RAID 1 array.
