Troubleshooting; Inside Out Method; Check Basic Diagnostic Tools; Check The Host Event Log - ATTO Technology iPBridge 1550D Installation And Operation Manual

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
ASCII-based interface

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/IP port
• LAN/WAN
• Ethernet host adapter or NIC in host
• Initiator

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.
