Notes 1. Some operating systems have size limitations for logical drives. Before you save the configuration, you might want to verify that the size of the logical drive is appropriate for the operating system. See the operating system documentation for more detailed information. 2. To change the configuration, select a Modify icon button. 5. Select the Apply button to accept and save the configuration. 6. If you have not already done so, install the operating system. See the server documentation or the documentation provided with the operating system for more information. After you install the operating system, see "ServeRAID device drivers and utility programs (installation)" on page 130 (or see the installation instructions provided with the server) for information about installing the ServeRAID device drivers and utility programs. Learning about custom configuration: The Custom Configuration path allows you to manually configure the ServeRAID subsystem. Using this path, you can select the drives that you want to include in each array, define the number and size of the logical drives for each array, and select the drives that you want to use as hot spares. Before you select the Custom Configuration path, consider the following: If you are not familiar with the IBM implementation of RAID technology, you might want to review the information provided in "Understanding RAID technology" on page 67 before you begin. Each ServeRAID controller supports a maximum of eight arrays. Each ServeRAID controller supports a maximum of eight logical drives. When you create an array, you group hard disk drives into one storage area. You can define this storage area as a single logical drive, or you can subdivide it into several logical drives. Each logical drive appears to the operating system as a single physical hard disk drive. If you have only one array, you can define it as a single logical drive, or you can divide it into several logical drives. Typically, the first logical drive defined on the first ServeRAID adapter or controller found by Netfinity 5500 M20 - Type 8662 75
