Before You Start Configuring

Before you start configuring your HP RAID 4Si controller, do these things:

Plan your physical drive and logical drive configurations (see the previous section, “Planning Your Configuration”).
Decide on the type of IRM configuration you want to do. To make that decision, consider these things:
- Whether you want to clear the existing configuration and start "fresh," or keep the existing configuration and add to it.
- Whether you want to do spanning (see step 5 under “Planning Your Configuration”).
To help you decide, Table 3-1 “Capabilities of Each Kind of IRM Configuration” below shows what you can do in each kind of IRM configuration.

Automatic Configuration is described in “Automatically Configuring Arrays and Logical Drives”.
Easy Configuration is described in “Using Easy Configuration”.
New Configuration is described in “Using New Configuration”.
View/Add Configuration is described in “Using View/Add Configuration”.

Overview of Configuration Flow

Figure 3-1 “Configuration Flow” below shows an overview of the flow you follow during a New Configuration or View/Add Configuration (an Easy Configuration is the same, except for the spanning steps [not allowed]). An Automatic Configuration does these steps for you (except for spanning, which is not allowed).

When you are finished with your configuration preparation, go to the next section, “Using IRM”.
