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.
