3ware Serial ATA RAID Controller User Guide
Software Installation Problems
The 3ware RAID controller was configured without problems, but
the system does not boot
The problem could be one or more of the following:
•
The BIOS may have changed the order of the boot devices. Check your
system BIOS boot sequence.
•
The 3ware BIOS will only boot from the first unit listed in 3BM. You can
change the unit from which the 3ware controller boots by moving it to the
top of the list of units by highlighting the unit and pressing the 'Page Up'/
'Page Down' keys.
•
The operating system is installed on a device that is not in your system’s
boot order. Use your system’s Setup utility to include the StorSwitch
controller in the boot order.
•
If your operating system was installed before you configured your RAID
units, you may have overwritten your operating system. Remember that
creating or deleting a RAID unit overwrites any existing data on the
member drives. Reinstall your operating system.
•
There may be a compatibility problem between the motherboard system
BIOS and the 3ware BIOS. Check the 3ware website (www.3ware.com)
to see if your motherboard is compatible with the 3ware BIOS, and check
with your motherboard manufacturer for potential BIOS updates.
A unit shows up as unusable, because of missing drives:
Unusable Arrays:
3 drive 64K RAID 5 558.77 GB (Unit 1)
SATA - Maxtor 6B300S0 279.86 GB (Port 6)
The unit has some but not all of its members available. The
unit will be unusable. If this unit is your boot device, your
system will not boot. You must either return the missing
disks to complete the unit, or release the member disks by
deleting the incomplete unit(s) listed in the display.
Remember that deleting a RAID unit overwrites any existing
data on the member drives.
CAUTION:
Do not delete the inoperable unit and recreate it, as this will
overwrite the data and make data recovery very difficult.
