Basic Verification

Troubleshooting

Verify Addressing

If working in FC-to-SCSI target mode and using Indexed or SCC Addressing, try
swapping to Auto Addressing to see if this solves the problem.

Verify Devices

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 host bus adapter or 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 configuration. It may also be useful to ensure that you are using a
current version of the host bus adapter driver.

Verify HBA Device Driver Information

Check the HBA device driver Readme file for configuration specifics. An HBA
may require a different configuration, depending on whether it is connected to a
loop or a switch.

RS-232 Port Problems

If you experience trouble communicating with the RS-232 port, verify the host
terminal emulation configuration. The PSFR-CP41 requires the baud rate to be
set correctly, 8 data bits, 1 stop bit, and no parity. Flow control should be
disabled, and may cause problems if set to ‘hardware’ or XON/XOFF. Some
hosts may not support baud rates higher than 19200, so a lower baud rate may
be required. If problems persist, you may want to check the cabling or try a
different host. If a valid Ethernet IP address is configured, RS-232 configuration
settings can also be set via SNMP and telnet.
