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. Refer to
ATTO
ExpressNAV pages
on page 21 to see which pages
may contain the information you need. You may also
look for information by using the diagnostic CLI
commands, enumerated in
Diagnostic commands
on
page 43, in the Advanced page of the ExpressNAV
interface, or by using the CLI directly (refer to
CLI
provides ASCII-based interface
on page 33.
To start and use the ExpressNAV interface, including
how to access the version information, refer to
ATTO
ExpressNAV interface
on page 19.

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:
• Fibre devices
• iPBridge Fibre ports
• iPBridge internal configuration
• iPBridge Ethernet/IP ports
• LAN/WAN
• Ethernet host adapter or NIC in host
• iSCSI OS driver
• OS
• Application

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 event and trace logs

Check the iPBridge event log through the Advanced
page of the ExpressNAV interface or through CLI.
Refer to
Diagnostic commands
on page 43. 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

If a non-fatal power supply problem occurs, or if a
problem is detected before shut down occurs, the
bicolor
Ready/Fault
LED flashes on the front and
back (connector) sides of the iPBridge 2700R/D and
on the front faceplate of the iPBridge 2700C. The
Fault
LED also flashes briefly during start up.
Off
means not ready,
green on
means ready, and
yellow
on
means faulted.
Inspect the iPBridge 2700C faceplate and iPBridge
2700R/D back (connector side) LEDs (see
Exhibit 5.0-1):
• a lighted green LED, embedded in the connector
of the Ethernet management port, indicates a
valid link. Off shows that no link is present.
• a blinking yellow LED, embedded in the
connector of the Ethernet management port,
indicates activity.
