o From the BIOS Main Menu select Embedded LAN and SCSI settings.
Disable “Embedded SE SCSI.”
2. Disable the embedded Symbios SCSI controller by pressing Ctrl + C during
boot up:
o Select “Change Adapter Status” and press Enter. Change both of the “Next-
Boot” settings for the SYM53C806's from ON to OFF.
3. Exit the utility and restart.
70 OpenServer 5.0.x reports “Spurious Interrupt”
Problem: OpenServer 5.0.x sometimes reports “spurious interrupt” messages
during start-up. This can occur when the NetRAID-4M is using the same interrupt
as the embedded SCSI controller.
Example: The LPr slot 3 shares its interrupt with the embedded SCSI and will
provoke the spurious interrupt message.
Resolution: To eliminate these messages, make sure the NetRAID-4M is assigned
a different interrupt, either manually or by moving the card to another slot.
71 Adding disks under SCO OpenServer 5.0.X
Problem: Owing to a software limitation, OpenServer’s method of statically
configuring each disk into the kernel can cause user confusion. The difficulty arises
from OpenServer’s convention for naming drives. The drive_config utility
overcomes this limitation by automatically creating the appropriate kernel entries
and then rebuilding/relinking the kernel.
Background: The drive_config utility automatically creates device special files in
the /dev/rdsk and /dev/dsk directories. These files are named in the c#t#d#s#
(controller number, target number, disk number, fdisk partition number) format. On
a data container, the files c0t0d0 and c0t0d0s0 point to the first container that was
created.
Resolution: The driver configuration script called drive_config must be run
manually at the end of the NetRAID-4M OpenServer driver installation or it will be
impossible to configure and access drives.
Run the drive_config program by entering the following commands:
cd /pkg/hpnraid/scripts
./drive_config
