Appendix B
Troubleshooting
64
Start unit request failed
The BIOS was unable to send a Start Unit Command to the device. Run the
SCSISelect utility and disable Send Start Unit Command for the device.
Time-out failure during …
An unexpected time-out occurred. Check SCSI bus termination. Try disconnecting
the SCSI peripheral cables from the host adapter and then starting the HP Server. If
the HP Server successfully restarts, check SCSI bus termination and cable
connections. One of the devices on the SCSI bus may be defective.
Attention! Too many devices are terminated on the SE
connectors
The SCSI host bus adapter BIOS has detected that more than two devices have been
terminated on the narrow SE SCSI segment. Verify the termination on the devices
connected to the internal and external connectors. Terminate only the SCSI device
at the ends of the cable. Remove or disable the terminators on the SCSI devices
between the ends of the cable.
Attention! Insufficient termination detected on the SE
connectors
The SCSI host bus adapter BIOS has detected that either only one or no devices have
been terminated on the narrow SE SCSI segment. Verify the termination on the
devices connected to the internal and external connectors. Terminate only the SCSI
device at the ends of the cable. Remove or disable any terminators on the SCSI
devices between the ends of the cable.
NOTE
The termination detection feature is only implemented on the
internal narrow SE connectors. The 68-pin LVD/SE connector
does not support this feature.
