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.

25

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.
