Troubleshooting
Manual No. 3000863 4-3
information is displayed without error, then the adapter is properly
communicating with the SCSI devices.
Figure 4-1. Device Scanning Dialog Box
If an attached SCSI device is not recognized, verify that each device
has a unique SCSI ID. The host adapter is set to SCSI ID 7 by default.
Disable Fast Transfer Rate. Some SCSI devices may not be capable of
negotiating a data transfer rate of 20/10 MBytes/sec. If a device cannot
support the higher rate, it is supposed to reject that value and propose a
lesser value it can support. Some older SCSI devices when requested to
negotiate at 20/10 MBytes/sec will halt operation. Try selecting a lower
negotiating data transfer rate or set the requested transfer rate to Async
in the View/Modify Device Configuration menu.
Motor Spin-Up. Some SCSI disk devices may not be configured to
spin-up on power-on or upon reset. This will cause an error if the
operating system attempts to access this device. When this occurs,
enable the Motor Spin-Up option in the AutoSCSI View/Modify
Device Configuration menu. If this option is enabled and the selected
device does not require this option to be enabled, the device will
probably ignore it.
Power. Be sure that all external SCSI devices are securely connected to
a power source.
Troubleshooting Startup
At system startup, the FlashPoint adapter performs a self-test, runs tests on
the SCSI bus, and performs SCAM on the SCSI bus devices. As these
operations are executing, screen messages appear briefly. When all the
operations are complete, a BIOS installation completion message is
displayed and your system should continue to boot. If the startup operations
do not complete successfully, an error message may be displayed. There are
also conditions under which an operation will not complete successfully and
the system will hang before an error message can be displayed. System hang
instances and error messages are shown below. Where possible, problem
resolution procedures are included.
