5 Troubleshooting
If it is clear that a particular component system is at fault in a problem situation, go directly to that component. If
it is not clear, the best approach is to troubleshoot using the inside-out method.
You may check on the status of your iPBridge using
the ExpressNAV interface. You may also look for
information by using the diagnostic CLI commands,
enumerated in
on page iii, in the Advanced page of the
ExpressNAV interface or by using the CLI directly.
To start and use the ExpressNAV interface, including
how to access the version information, refer to
Inside out method
To troubleshoot using the inside out method, begin with the device(s) connected to the iPBridge first, then work
your way out.
• SCSI
devices
• iPBridge SCSI port
• iPBridge internal configuration
• iPBridge Ethernet/iSCSI port
• LAN/WAN
• Ethernet host adapter or NIC in host
• Initiator
• OS
• Application
Check basic diagnostic tools
Check the host event log
Check the event log on the host. Look for the most
recent entries and determine what could be causing a
problem, then go to that event and continue
troubleshooting.
Check the iPBridge event and trace logs
Check the iPBridge event log through the CLI. Look for
the most recent entries and determine what could be
causing a problem. Then go to that event and continue
troubleshooting.
Visually inspect LEDs
Light Emitting Diodes (LEDs) are located the back of
the iPBridge.
Each SCSI bus has its own LED which lights when the
iPBridge is ready and blinks steadily when there is
SCSI activity.
Check for problems on attached devices
Check the following in order to find problems on
attached devices:
• LEDs
• Display
panels
• Firmware
levels
• Operability
Check host versions
Check the following to find problems on attached
hosts:
• Operating
system
version
• Service pack version
• Host
adapter
version
• Host adapter firmware version
• Host adapter device driver version
• iSCSI
driver
version
