• A common mistake is when enabling CHAP only for a device after the initial discovery by the
initiator. It will be necessary to remove the address from the discoveries tab and recreate it
with the appropriate CHAP settings, otherwise any rediscoveries will be attempted without
CHAP and no devices will be returned.
• Reboot the devices and the Gateway.

Poor Performance
Poor performance can be caused by many differing reasons. The following checklist is provided as
a guide to where you may find ways to improve performance.
• Packet loss can be a cause of poor performance. Within the
Link Status Box
check the
number of
TX
and
RX
errors for both network interfaces that are displayed on each
Network
Port
page. This should be zero or a very small number. If these are showing large numbers
of errors, check the connections between the Gateway and the target. See Section 4.1.2:
for more information.
• Check that the entire network cabling between the target and the Gateway is of the correct
standard. See Section 2.1:
Connecting the Ethernet Interface
and Section 2.2:
•
Data Digests
are an extra level of error checking on top of the standard TCP/IP checksum
error checking (configured on the initiator). However, the calculation of these extra checksums
can greatly affect overall performance. Therefore,
Header and Data Digests
should only be
enabled where the integrity of the network connection is in doubt.
• By enabling
Jumbo Frames
as explained in Section 4.1.2.1:
you can improve
the throughput performance of the Gateway. This will only work if
all
of the components in
the infrastructure between the target and the Gateway are enabled for jumbo frames. That
includes the Host Bus Adapter (HBA), all switches and routers, and the Gateway itself. If any
of the components are not enabled or not capable of handling jumbo frames, then unexplained
packet loss or corruption may occur.
If none of the above resolves your problem, please contact support. See Appendix B:
for information on how to contact Bridgeworks Support.
Lost IP Address
The utility “LAN Scan” can be used to find any device irrespective of its IP address. This can be
helpful in determining the IP address of a Bridgeworks device with an unknown IP address and for
