106 Troubleshooting Chapter 5
Verify Configuration
A number of configuration changes may result in an invalid configuration. If
you are in doubt about the configuration, restore the IM to the factory default
configuration, and configure the IM one step at a time to verify the
functionality of the configuration as changes are made.
Verify Devices
It may be useful to connect the SCSI target devices you are attempting to use to
the native SCSI interface to verify that the devices are functional. SCSI target
devices can be connected to a host SCSI bus to verify they are functional.
Verify Host Configuration
In some cases, it may be that the FC host bus adapter or host device driver
may not be working properly. Check the configuration of these elements. It
may be useful to check the release notes for the driver provided to see if there
are any specific issues or required configurations. It may also be useful to
ensure that you are using a current version of the HBA driver.
Check the Windows NT System Log using the Event Viewer to verify that the
HBA driver is functioning properly.
Verify HBA Device Driver Information
Check the HBA device driver Readme.txt file for configuration specifics. An
HBA may require a different configuration, depending on whether it is
connected to a loop or a switch. HBAs typically come with utility programs that
can be used to view or change their configuration.
Serial Port Problems
If you experience trouble communicating with the serial port, verify the
configuration of the host terminal or terminal emulation program. The IM
requires the baud rate set to 9600, 8 data bits, 1 stop bit, and no parity. Flow
control should be set to none or XON/XOFF, and may cause problems if set to
hardware. If problems persist, you may want to check the cabling or try a
different host.
