Option ROM Configuration for Arrays About ORCA ORCA is a ROM-resident array configuration utility that executes automatically during initialization of an HP Smart Array controller. This utility is designed to enable a logical drive to be configured on a new HP server before the operating system is installed: • If the boot drive has not been formatted and the boot controller is connected to six or fewer physical drives, ORCA runs as part of the auto-configuration process when the new server is first powered up. During this auto-configuration process, ORCA uses all of the physical drives on the controller to set up the first logical drive. The RAID level used for the logical drive depends on the number of physical drives (one drive = RAID 0; two drives = RAID 1+0; three to six drives = RAID 5). If the drives have different capacities, ORCA locates the smallest drive and uses the capacity of that drive to determine how much space to use on each of the other drives. • If the boot drive has been formatted or if there are more than six drives connected to the controller, you are prompted to run ORCA manually. For more information about the auto-configuration process, see the HP ROM-Based Setup Utility User Guide on the Documentation CD that is provided with the server. ORCA is available in two formats: • Using the ORCA menu-driven interface • Using the ORCA CLI HP ProLiant 100 Series servers do not support the CLI format. For these servers, use the menu-driven interface. Either format provides a quick and easy method for basic logical drive configuration. Both formats have limited support for standard configuration tasks (on page 6). However, these few tasks are adequate if your configuration needs are simple. For example, stripe size is predetermined by the RAID level that you choose, and the size of the logical drive is determined automatically by the size of the physical drives that you select.

Option ROM Configuration for Arrays
About ORCA
ORCA is a ROM-resident array configuration utility that executes automatically during initialization of an HP
Smart Array controller. This utility is designed to enable a logical drive to be configured on a new HP server
before the operating system is installed:
•
If the boot drive has not been formatted and the boot controller is connected to six or fewer physical
drives, ORCA runs as part of the auto-configuration process when the new server is first powered up.
During this auto-configuration process, ORCA uses all of the physical drives on the controller to set up
the first logical drive. The RAID level used for the logical drive depends on the number of physical drives
(one drive = RAID 0; two drives = RAID 1+0; three to six drives = RAID 5). If the drives have different
capacities, ORCA locates the smallest drive and uses the capacity of that drive to determine how much
space to use on each of the other drives.
•
If the boot drive has been formatted or if there are more than six drives connected to the controller, you
are prompted to run ORCA manually.
For more information about the auto-configuration process, see the
HP ROM-Based Setup Utility User Guide
on the Documentation CD that is provided with the server.
ORCA is available in two formats:
•
Using the ORCA menu-driven interface
•
Using the ORCA CLI
HP ProLiant 100 Series servers do not support the CLI format. For these servers, use the menu-driven
interface.
Either format provides a quick and easy method for basic logical drive configuration. Both formats have
limited support for standard configuration tasks (on page
6
). However, these few tasks are adequate if your
configuration needs are simple. For example, stripe size is predetermined by the RAID level that you choose,
and the size of the logical drive is determined automatically by the size of the physical drives that you select.
