78 Configuring and Managing RAID
RAID Configuration Functions
After you attach physical disks, use a configuration utility to organize the
disks into virtual disks. If the operating system is not yet installed, use the
BIOS Configuration Utility to perform this procedure.
Use the configuration utilities to perform the following tasks:
• Access controllers, virtual disks, and physical disks individually
• Select a host controller to work on
• Create hot spare physical disks
• Configure virtual disks
• Initialize one or more virtual disks
• Perform consistency checks
• Rebuild failed physical disks
• Preserve the cache data, known as pinned cache, from a virtual disk that
goes offline or is deleted for any reason
The following sections describe the menu options and provide detailed
instructions to perform the configuration tasks. They apply to the BIOS
Configuration Utility. You can configure physical disks into virtual disks by
following the procedure below.
1
Define virtual disks using a group of physical disks.
NOTE: A disk group is deleted when the last virtual disk in the disk group
is deleted.
2
Designate hot spares (optional).
For more information, see "Managing Dedicated Hot Spares" on page 94.
3
Save the configuration information.
4
Initialize the virtual disks.
For the detailed configuration procedures, see "Physical Disk
Management" on page 105.
