not showing up, contact your service 
representative.

If all devices appear, invoke the ScsiTargets 
command several times on each SCSI port to 
verify that the devices can be seen. If devices 
disappear then appear again, the problem is 
most likely a SCSI cable. For information on the 
ScsiTargets command, refer to 

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 using either the 
saveConfiguration CLI command or through the 
ATTO ExpressNAV interface.

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

2

Verify that your serial cable is less then two 
meters in length.

Verify that the SCSI devices are mapped properly. 
Check in the ATTO ExpressNAV interface or use the 
routedisplay iSCSI

 

command to show mappings. If 

devices do not appear, power down the iPBridge and 
power back on. Refer to 

 on page 15 and 

Mapping commands

 on page 57.

When changing any setting on the iPBridge, the 
configuration must be saved by using either the 
saveConfiguration CLI command or through the 
ATTO ExpressNAV interface.

1

Check Ethernet cable integrity. Check the 
cables for solid connections. Cat5 cable can 
cause connection issues with Gigabit Ethernet. 
Cat6 cable is 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 

3

Verify that the Ethernet speed is set to auto: 
invoke the get EthernetSpeed all command, 
check the Ethernet page of the ATTO 
ExpressNAV interface, or check the LED link 
lights to determine if the Ethernet speed is 
correct.

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. Refer to 

page 10.

5

Verify that each used Ethernet port on the 
iPBridge can be pinged from the desired host. 
Refer to 

If the host cannot ping the iPBridge ports and 
the iPBridge ports are properly configured, 
continue to the Local Area Network/Wide Area 
Network section, 

page 29.
Verify that each port on the iPBridge can ping 
each desired host. Refer to 

the iPBridge cannot ping the host, continue to 

6

If using DHCP, verify that the DHCP server is 
assigning the correct IP information to the host.

7

Some older switches/hosts cannot auto 
negotiate between the iPBridge and the 
switch/host at the desired speed. You may 
have to force the host/switch or the iPBridge to 
the desired speed.

8

Verify that the host is logging into the iPBridge 
correctly by viewing the Connections page 
and determining if there a “session open” 
status.

9

Verify that you are using the correct log in 
procedure for your initiator. For example: When 
connecting using the Adaptec initiator, the log 
on screen requests the iPBridge iqn (iSCSI 
qualified name). If left blank, Adaptec cannot 
log in. Enter “iSCSI” into this field for auto iqn 
discovery.

When changing any setting on the iPBridge the 
configuration must be saved by using either the 
saveConfiguration CLI command or through the 
ATTO ExpressNAV interface.

1

Verify that the switch/switches are segmented 
properly so that hosts and the iPBridge have 
access to each other.
