60 Chapter 5 BIOS Configuration Utility
View Array Details
This option allows the details of the array to be viewed. Nothing can be changed from this menu option; it is for
informational purposes only.
1.
From the Main Menu, select
View Disk Details
.
2.
Use the arrow keys to choose an array.
3.
The full details of the array are displayed in both the Information field across the top:
•
Array Number
• Type
• Size
• State
NOTE:
The disks list shows the disks in the array, as selected (green).
Rescan All Channels
This option allows the user to rescan all channels to detect new or removed disks and arrays.
• To perform a rescan, select
Rescan All Channels
from the Main Menu. (The activity indicator in the
Information field spins while the disks are being polled).
• The Rescan All Channels option rescans all the channels, searching for new or removed disks, and rereads
the configuration information from each disk.
NOTE:
Sometimes when a disk is offline, it can be brought online through a rescan. Rescan also stops, and
then automatically resumes, all tasks.
Change the Controller Options
Selecting
Controller Options
allows the user to configure whether RAIDCore arrays might be bootable, as
well as other aspects of the boot process.
The default is to configure an array. An operating system can boot from RAIDCore. If an error occurs, an error
message is displayed.
However, the user might be booting from the motherboard IDE or another SCSI device in the system. If this is
the case, do not enable INT13 (without INT13, DOS cannot see the array).
NOTE:
If Boot Mode is configured to enable INT13 and never display an error message, the user will not
know during the boot process if an array is degraded or if other problems have occurred.
One symptom of having too much memory used by the BIOS Configuration Utility is a blank window, with the
message “Couldn't initialize memory” appearing in the top left hand corner. No additional information is given.
This menu also sets whether the boot process will pause when an error occurs. When the Pause feature is
enabled and an array goes critical or offline, or there is a RAIDCore configuration error, the boot process stops.
Press
Enter
to continue booting.
View the error message on the window. If the Pause feature is disabled, the error message is displayed briefly,
but the system continues to boot.
