A legacy disk is an IDE or SATA disk that was previously used on a standard parallel or SATA controller.
RAIDCore BC4000 Series RAID controllers can read from and can boot from legacy disks, but many of the
advanced RAID functions are not available for legacy disks. If additional disks are available, a legacy disk can
be transformed into a RAID array.
If you want to boot from a legacy disk attached to a BC4000 Series RAID controller, you must first install the
controller driver.
To boot from a legacy disk attached to a BC4000 Series RAID controller:
1.
Shut down the system.
2.
Insert the controller into the system without any disks attached and boot the system.
3.
Install the controller drivers for your particular operating system. (See
“Windows: Installing Drivers and
Applications” on page 22
or
“Linux: Installing Drivers and Applications” on page 28
.)
4.
Shut down the system and connect the legacy disk to the BC4000 Series RAID controller. If you are using an
IDE drive, you must have a parallel-to-serial converter.
5.
Boot the system.
You should now be booting from the legacy disk. If additional disks are available, you can transform the legacy
disk into any larger size and type of RAIDCore array. See
“Using Legacy Disks” on page 43
for more information.
Note:
For this procedure, you do not need to initialize disks or create arrays when installing the
controller drivers.
Caution!
For parallel ATA legacy disks, Broadcom does not support the extended use of parallel-to-
serial converters. Data loss may occur. Broadcom suggests that if you use a converter, use it only
temporarily to include a parallel drive in a RAIDCore array and to transfer the data to a serial drive.
Note:
You should be able to see that a legacy array exists in the RAIDCore BIOS.
