Controller features The HP Embedded SATA RAID Controller enables you to create arrays with RAID levels 0 and 1 on SATA hard drives in specified HP ProLiant server models. For a complete list of the controller attributes and information about the compatibility of particular operating systems with the controller, refer to the HP website (http://www.hp.com). Installing the driver A link to the downloadable driver for the controller is provided on the controller-specific page of the HP website, http://www.hp.
Configuring an array Two utilities are provided to enable you to configure arrays on the controller: • The menu-based RAID Configuration Utility, located on the controller BIOS, enables you to configure an array even before the driver or operating system is installed. However, this utility can be opened and used only while the system is rebooting, before any installed operating system is loaded. Also, you cannot change the properties of an existing array using this tool.
The Array Properties menu appears, showing the RAID levels (types of array) that can be configured for the selected number of drives. (For this controller, RAID 0 and RAID 1 are shown. Both of these RAID levels require two drives.) 8. Select the RAID level that you want to create, and press the Enter key. 9. (Optional) Enter a label of no more than 15 characters to identify the array. 10. If you are creating a RAID 0 array, select the stripe size that you want the array to use.
NOTE: A maximum of two physical drives are supported per RAID set. The controller is capable of supporting multiple RAID sets. 3. Press the Esc key to return to the previous menu. Making an array bootable 1. From the main menu of the array configuration utility, select Manage Arrays, and press the Enter key. 2. From the List of Arrays, select the array that you want to make bootable, and press the Ctrl+B keys. An asterisk appears next to the array to indicate that it is bootable.
System shutdown rebuild 1. Power down the system. 2. Replace the failed drive with a new one of equal or greater capacity. 3. Restart the system. 4. At the appropriate prompt during POST, press the Ctrl+A keys or the F8 key to access the RAID Configuration Utility. 5. From the menu, select Array Configuration Utility. 6. From the main menu of the array configuration utility, select Add/Delete Hotspares. 7. Assign the new drive as a hotspare. This starts the Rebuild task.
