The
Identify Disk
option can be used within RAIDConsole to physically identify a disk. By selecting a disk
within RAIDConsole and using this feature, you can cause the LED on the controller or a disk enclosure to blink
for that disk. If you have a failed disk, this feature can be used to physically identify which disk in the enclosure
has failed.
To use LEDs to identify a disk:
1.
In the
Disk List
area, right-click the disk that you want to identify.
2.
When the
Options
window is displayed, click
Identify Disk using LEDs
, and then click
OK
.
When the
Identify
window is displayed, the LED for that disk begins to blink.
3.
To stop the LEDs from blinking, click
Stop Identify
.

Unlike many RAID controllers, the RAIDCore BC4000 Series RAID controllers allow the partitioning and
creation of as many as eight arrays across all disks. Portions of disks can be used to create arrays while other
arrays are using different portions of the same disks, but a maximum of eight arrays can be created.
Note:
If the LED cables between a disk enclosure and the controller are not properly connected, the
wrong disks may be identified.
Notes:
•
Creation of arrays, even redundant arrays, allows users immediate access to the arrays, unless
the zero option is used during the create.
•
If the system reboots, the creation process continues where it left off.
•
Array numbers are valid only for a given boot, and may be different in the BIOS and drivers. If a
permanent label is required, use the labeling feature described in
“Naming Arrays” on page 83
.
•
In some circumstances, having more than eight arrays is possible and may appear to function
properly, but is not supported by Broadcom.
•
The array size of the new array is limited to 2.199 TB on some versions of Windows and Linux.
Please refer to your OS documentation for details on maximum array sizes.
