Troubleshooting Guide

Problem The DPT SCSI BIOS copyright message appears twice at power-up.
Solution Several things could be causing this problem:
1. The system BIOS may be incorrectly shadowing the DPT SCSI BIOS as a
video BIOS. Disable all shadowing through the computer's system setup. If
the problem is still present then re-enable shadowing.

2. If there are multiple DPT adapters, more than one adapter may have its
SCSI BIOS enabled. Assure that only one adapter has its SCSI BIOS
enabled.

Problem When the DPT SCSI BIOS displays the SCSI devices at system boot-up, one
device appears at all seven SCSI IDs.
Solution One of the SCSI devices has been set to the same ID as the DPT adapter.
The SmartRAID adapter is set by default to SCSI ID 7. Assure that all SCSI
devices have a unique ID

Problem The message "Warning: SCSI BIOS ROM version is later than this driver
version." is displayed during DOS boot-up.
Solution This message will occur when the revision of the ROM-based SCSI BIOS is
newer than the revision of DPTDDL.SYS. The revision level of DPTDDL.SYS
must be equal to or newer than the ROM-based SCSI BIOS revision.

Problem During normal system operation under Novell Netware, the message "DPT
CTRL h DISK d resetting controller." where h = host adapter number and d =
SCSI device ID, is displayed.
Solution Any time that a SCSI device does not respond to a request from the
SmartRAID adapter, the adapter will reset the device and retry the request
and this message will be displayed. Verify proper SCSI bus termination and
cable installation. Otherwise a faulty SCSI device or cable is probably the
problem.

Problem The adapter does not respond during boot-up after the DPT SCSI BIOS
copyright message is displayed, and LEDs 1 and 2 or 1, 2 and 10 remain lit.
Solution Either the SCSI bus is improperly terminated or the SCSI cable is on
backwards.

Problem When attempting to run Storage Manager under DOS, the message "Cannot
Enable A20" is displayed.
Solution Load HIMEM.SYS by adding the following statement to your CONFIG.SYS file:
DEVICE = HIMEM.SYS

Problem LEDs 1 - 8 rotate back and forth in super-fast rotating pattern and an EISA
Configuration Error is displayed at power-up.
Solution This pattern indicates that the EISA SCSI adapter has not been configured by
the motherboard or ECU. Ensure the adapter is in a Bus Master slot and run
the ECU provided with the motherboard. This pattern can also occur when the
adapter is properly configured but a SCSI cable has been attached backwards
or the SCSI bus has been improperly terminated.

Problem LED 9 (and any other LEDs) remain lit and the adapter does not respond.
This may occur during the loading of Microsoft Windows 3.1.
Solution LED 9 indicates that the adapter's IRQ is pending. This usually indicates an
IRQ conflict with another card. Assure that each card is set to a unique IRQ. If
you are running Microsoft Windows 3.1 then add the following line to the
SYSTEM.INI file under 386ENH section:

VirtualHDIrq=OFF
Alternatively, Windows can be started with a WIN /D:V if you do not want to
modify the SYSTEM.INI file.

Problem Various LEDs in the 1 - 4 range flash once per second and the adapter does
not respond.
Solution This pattern indicates an internal Microprocessor Trap in the adapter. Remove
all SCSI devices, cables and option modules and retry. If the Trap Error
disappears, reconnect everything, one device at a time, until the faulty device,
cable or module is isolated. Microprocessor Trap can also occur because of a
firmware EPROM error during normal operation. Try reseating the EPROMs
in their sockets to assure good contact.

Problem LEDs 1, 2 and 8 flash once per second at power-up and the adapter does not
respond.
Solution This pattern indicates that there is no SIMM in socket #1 of the SmartRAID
adapter. Socket #1 must always contain the largest capacity SIMM.

Problem LEDs 2 and 8 flash once per second at power-up and the adapter does not
respond.
Solution This pattern indicates that there is no SIMM in socket #1 of the SmartRAID
adapter does not contain the largest SIMM. Rearrange the SIMMs so that the
largest capacity SIMM is in Socket #1.

Problem LEDs 3 and 8 flash once per second at power-up and the adapter does not
respond.
Solution This pattern indicates that a combination of parity and ECC SIMMs have been
installed on the SmartRAID adapter and SIMM Socket #1 does not contain a
parity SIMM. Rearrange the SIMMs so that a parity SIMM is in Socket #1, or
do not mix parity and ECC SIMMs.

Problem LEDs 3 and 8 flash once per second at power-up and the adapter does not
respond
Solution This pattern indicates that the adapter has detected a problem with the SCSI
cable termination.

Problem Some other combination of LEDs not listed above flash once per second at
power-up and the adapter does not respond.
Solution This indicates a firmware trap has occurred. To determine the cause of the
trap, run Storage Manager (from floppy if necessary) while the LEDs are still
flashing. A description of the problem and possible solutions will be displayed
upon entering the program.

Problem Although the SCSI devices can be accessed by the SmartRAID adapter, the
amber fault LEDs on the devices in the SmartRAID Storage Cabinet do not
flash during boot-up and the SmartRAID adapter does not detect drive swaps
or cabinet failures.
Solution These symptoms indicate that the SmartRAID Storage Cabinet status signals
are not being properly received by the SmartRAID adapter. One cause can be
another SCSI device or non-DPT cabinet connected to the external SCSI
cable along with the SmartRAID cabinet. Other devices will typically ground
these signals.
