Currently Being ModeratedApr 7, 2006 7:40 AM (in response to rcsjt)Is your metadata on a seperate LAN? If not, then it wasn't implemented correctly. Losing your Internet link -- or your main LAN (I'm assuming in this case) shouldn't affect Xsan one bit.
Currently Being ModeratedApr 7, 2006 9:32 AM (in response to sapridyne)Yes, every Xsan client and mdc has two active ethernet ports, one for metadata and one for the main lan, with separate subnets and everything.
Currently Being ModeratedApr 7, 2006 10:53 AM (in response to rcsjt)This may have nothing to do with your problem, but...
In System Preferences, under Network, when you click on Show: Network Port Configurations, the port you use for the internet connection should be listed above the port for your metadata. Just a suggestion, keep in mind that it may be something simpler than DNS. Or not. Who knows?

Currently Being ModeratedApr 10, 2006 6:55 AM (in response to rcsjt)Is it possible that on your metadata controllers and possibly even your servers and RAIDs that your gateway is set to your EXTERNAL gateway as opposed to your internal DHCP machine? That would cause this kind of issue if it cannot reach the internet. Even if it doesn't use it, it still checks it and gets a litty "moody" if it's not there.

Currently Being ModeratedApr 10, 2006 11:18 AM (in response to James Knotts)All of the machines have nothing set as the default gateway (on the metadata lan). Should there be something set?
Currently Being ModeratedApr 19, 2006 9:56 PM (in response to rcsjt)Does anyone have any advice. I have the exact same setup and the exact same problem.
My General Office LAN is 10.0.10.x with a Cisco PIX router at 10.0.1.1. Each machine has a fixed IP in the 10.0.10.xxx range. My XSAN metadata network does not have a router, and each machine has a fixed IP in the 10.0.50.xxx range. If I start up with the Cisco PIX router turned off, the nodes do not connect to the XSAN.G5, Mac OS X (10.4.6)
Currently Being ModeratedMay 15, 2006 1:26 PM (in response to rcsjt)Try this: In Server Admin, DNS Settings turn off both Zone Transfers and Recursion. This will keep the DNS service from going outside for requests or forwarding your DNS info to outside servers. This means that your client computers must also list an outside DNS (in addition to your internal one) in order to get on the internet.

Currently Being ModeratedMay 17, 2006 5:05 AM (in response to PaulRS)The lookup order for hostnames is default:
LookupOrder: Cache FF DNS NI DS
So by manualy editing the /etc/hosts file you do not depend 100% on your DNS which is good...
Your DNS should always reflect the right IP addresses for hostnames and vice versa... You should check this I think...
netstat -nr should provide you the default routing table...
MacOs X doesn't function correctly without a gateway for your NIC's...
