Frequently Asked Questions

Q: Can I boot from an array?
A: Yes, you can boot without any problem from an array.
Q: If you have two UltraWide SCSI drives connected to the RAID
controller, does one of them have to be the bootable drive?
A: No, the entire RAID array is bootable rather than the individual
drives that make up the array. If there are two drives configured in a
RAID 0 array, the array will automatically be bootable.
Q: Can a third UltraWide SCSI hard drive be added to be used as
the boot device, as defined in the support boundaries?
A: Yes, you can add a third drive, but the third drive cannot be included
in the same RAID array. For example, you could create a RAID 1 array
with two drives plus a third drive configured as a spare. Or, you could
configure two arrays: one with two drives and one with one drive.

Q: Can I connect a third SCSI drive to the Narrow SCSI controller
A: You can connect a third drive to the Symbios controller, but both the
Symbios BIOS and FastRAID BIOS cannot be loaded at the same time.
That means that you cannot boot from both SCSI devices at the same
time. If you only need to boot from the Symbios SCSI occasionally, then
you can disable (from BIOS setup) the Internal Wide 16-bit SCSI
and enable the Symbios SCSI to
Option ROM Scan Option ROM Scan
boot on the Symbios SCSI. When you're finished, disable the Symbios
SCSI and enable the Internal Wide 16-bit SCSI
Option ROM Scan
.
Option ROM Scan
NOTE
You cannot change the priority of RAID and non-RAID devices through
the ArrayConfig utility's Custom Setup routine. RAID devices will
always have the highest priority even if the SCSI address of the
non-RAID device is set to 0.
