second ethernet card hangs up

[admin@beatson.gla.ac.uk]

I have an open-e nas xsr enterprise

Model: Open-E NAS-XSR ENTERPRISE
Version:3.10.XE00000000.2364
Release date:2006-11-14


this has two onboard ethernet cards. I have segmented my lan so that my clients connect over 1 ip range and my backup server and application servers over a second private address space. This means that most of my backup and work traffic never routes outside the switch the open-e nas is attached to.

The open-e unit is about 1 week old. When I configure the two ethernet cards they both work perfectly, I can map drive to the addresses on both the first and second ethernet cards. However after about 15/20 minutes the second ethernet card stops responding. I can reproduce this using ping. Both cards respond then eth1 stops responding after 15 minutes. The only way to bring eth1 back to life is to reboot (power cycle) the nas. The supplier has replaced the motherboard in the unit.


I have a fealing that this is not faulty hard ware but may be a problem with the kernel, but I could be wrong.


Is anyone else experiencing this problem or has a soloution for it?

Can you try with using a crossover cable. Also see if you can try using another approved NIC from our web site compatibility listings. If this does not help please send logs to support@open-e.com

OK this morning I added a 3com card. It is seen by the nas and works fine as long as the ip address is in the 130.xxx.xxx.xxx range as soon as I set it to 172.xx.xxx.x range then the card responds for about 15 minutes then hangs up.

The critical_error.log file shows the following:

Dec 15 18:32:42 nas ip_test_log: WARNING: Two or more network adapters are in the same subnetwork.

Please check to see if there is another duplicated IP Address on the network.

I have checked and no duplicate ip address in the network.

I run ping 172.xxx.xxx.xxx -n 1000. There is no reply until the nas is power cycled. The I get a response for about 15 minutes then no more response.

Can you test this using a 10.x.x.x network (using a crossover) and a 192.168.x.x. Then test with crossover to the 172.x.x.x.

Are you using any Jumbo frames?
