Troubleshooting
Problem: The controller does not respond and various LEDs in the 14 range flash
once per second.
Solution: This pattern indicates an internal microprocessor trap occurred in the
controller. Remove all attached devices, cables and option modules and
retry. If the trap error disappears, reconnect the cables and devices, one
device at a time, until the faulty device, cable or module is isolated. If the
error persists, contact DPT Technical Support.
Problem: Pressing Ctrl+D to access SMOR does not work or the information
displayed is garbled.
Solution: If this happens, use the following procedure to restore the parameters in
the NVRAM to their default settings:
1. Turn off power to the system.
2. Place a shorting jumper across pins 1 and 2 of P4 on the controller.
3. Power on the system and wait until the LEDs 3, 5, 7 and 8 on the
controller begin flashing.
4. Turn off power to the system and remove the jumper.
The controller can now be reconfigured using SMOR or Storage Manager.
Problem: During the installation of SCO UNIX with a DPT PCI controller the
following message appears:
Warning: SCSI controller cannot install interrupts
vecno=xx, type = 2, IPL=5
Vector xx is private.
Solution: SCO UNIX reserves certain interrupts for its internal use. This error
indicates that the DPT controller has been assigned one of these reserved
interrupts. Assign a different interrupt to the controller and start the
installation again.
Problem: You want the system to boot from a drive that is not attached to a DPT
controller. However, during boot, the DPT I
2
O BIOS message appears first
which indicates that a drive attached to a DPT controller will be the boot
drive.
Solution: Use SMOR to modify the Bootable Devices parameter by selecting
Disabled. This will prevent the DPT controller from being used as the
booting controller for system.
