Check components
Use this procedure to check system components.
For more information on the commands used in
this procedure, refer to
CLI provides an ASCII-
based interface on page i of the Appendix.
Check Fibre Channel devices
1 Check Fibre Channel device power. Make sure
the devices are powering up.
2 Watch the drive lights before, during, and after
startup.
3 Check cable integrity. Check the cables for
solid connections.
4 If the problem persists, try drives one at a time
with different cables, adding drives and cables
until the problem occurs. This helps pinpoint the
drive or cable causing the problem.
5 Check with the manufacturer of the device(s)
for further troubleshooting methods.
If Fibre Channel devices appear to be working
order, move on to the iPBridge Fibre Channel port
section.
Check the iPBridge FC ports
1 Either through the ATTO ExpressNAV or CLI,
check the devices on each port.
If no devices appear, re-check cables. If
garbage information appears, the problem is
most likely a bad cable.
2 Check the internal cabling of the device.
3 If all devices appear, invoke the FCTargets
command several times on each port to verify
that the devices can be seen. If devices appear
and disappear, then appear again, the problem
is most likely a cable. For information on the
FCTargets command, refer to
FCPortList on
page viii of the Appendix.
If all devices appear and remain, move to the
iPBridge internal configuration section.
When changing any setting on the iPBridge, the
configuration must be saved by clicking on the
Save button on the ATTO ExpressNAV interface
screen
or using the saveConfiguration CLI command.
Check the serial port
1 Verify you have the correct settings and that
your terminal is configured to:
• Baud rate: 115200
• Data bits: 8
• Stop bits: 1
• Parity: off
• Flow control: None
• Echo: off
2 Verify that your serial cable is less then two
meters in length.
Check iPBridge internal configuration
Verify that the Fibre Channel devices are mapped
properly using the ATTO ExpressNAV interface.
If devices do not appear, power down the
iPBridge and power back on. Refer to
Using
ExpressNAV on page 27 and Target
management on page 11.
When changing any setting on the iPBridge, the
configuration must be saved by clicking on the
Save button on the ATTO ExpressNAV interface
screen or using the saveConfiguration CLI
command.
Check iPBridge Ethernet ports
1 Check Ethernet cable integrity. Check the
cables for solid connections. Cat5 cable can
cause connection issues with Gigabit Ethernet.
Cat5E and Cat6 cable are the best cabling for
the iPBridge.
2 Verify the IP address, subnet mask, and
gateway are properly set on each data port on
the iPBridge for your network environment.
Refer to
Using ExpressNAV on page 27.
3 Verify that the Ethernet speed is set to auto:
check the Ethernet page of the ATTO
ExpressNAV interface, or check the LED link
lights to determine if the Ethernet speed is
correct. Refer to
Visually inspect LEDs on page
20.
4 Determine if the iPBridge is set to get its IP
information from a DHCP server. If so, verify
that the DHCP server has available IP
addresses.
