Installation Issues
(Capacity, Booting)
Q: Why are some drives recognized by the FastTrak S150 TX2plus Array
Setup utilities with only partial capacity?
A: Some hard drives ship with a jumper that reduces the addressable capacity
of the drive to prevent problems with older systems that don’t support larger
drives. Consult your hard drive documentation to set the jumper so that you can
use the full capacity of the drive.
Q: How can I change the system boot sequence in order to boot from the
FastTrak S150 TX2plus array?
A: The boot sequence is controlled by the system BIOS. As far as the system
BIOS is concerned, the FastTrak S150 TX2plus controller and defined arrays
are categorized as a SCSI device. This allows you to set the boot sequence in
your BIOS setup utility to boot from SCSI first, rather than IDE.
If there are multiple SCSI add-in controllers in the system, then the boot
sequence among them will be determined exclusively by their PCI slot priority.
PCI slot #1 will be first, slot #2 second, etc. Put the FastTrak S150 TX2plus
controller in the PCI slot where it will be accessed ahead of other SCSI
controllers if you want to boot from the array.
Q: How can I change the boot sequence between a PCI SCSI card and the
FastTrak S150 TX2plus RAID array?
A: Since all PCI devices are PnP, it is difficult to determine which device is
addressed first. Some newer motherboard BIOSes have advanced options that
identify devices and allow you to select which device will be assigned resources
first. Otherwise you may have to physically switch the device cards on the PCI
slots so that the boot device is in the highest priority slot number (see previous
question).
Post-Installation
Q: Why can’t I see the drives on the FastTrak S150 TX2plus under FDISK?
A: You have not created an array yet. If no array has been created, the system
will not recognize drive(s) attached to the FastTrak S150 TX2plus.
