7.5 Troubleshooting
Some potential problems and their suggested solutions are:
You cannot access the SCSI device(s).
•
Make sure the SCSI device driver is installed properly.
•
Make sure each device has power.
•
Verify that the appropriate BASEDEV= line ( BASEDEV=SYM8XX.ADD /V
or BASEDEV=SYM_HI.ADD /V ) exists in the CONFIG.SYS file.
•
Check the ordering of BASEDEV= entries in the CONFIG.SYS file to be
sure that the boot device is loaded first.
•
Verify that the correct driver is in the appropriate directory
(
\OS2\BOOT ).
•
Check the cable connections and the host adapter installation.
•
Verify that the adapter is not turned off in the SCSI BIOS
Configuration Utility and that the adapter is not excluded using the
/EXCLUDE command line option.
The computer hangs or locks up when booting and the SCSI
devices attached are not seen by the computer system.
•
Make sure that all the SCSI devices are configured at different ID
numbers. If booting the system from a device on the SCSI bus, the
boot drive must have the lowest ID or the highest ID. This depends
on the scan order option selected in the SCSI BIOS Configuration
Utility.
•
Make sure both, but only, the ends of the SCSI bus are terminated.
•
Make sure the device driver is listed in the CONFIG.SYS file and loads
when the system boots.
