add more updated info in this thread discuss: We compared local harddisk booted system with network booted system such as NFS booting or iscsi booting. When two NIC interface exists on the test host, and both use DHCP dynamic IP configure within different subnet, unplug one interface's network cable then compare result: local harddisk booted system can dynamic route the IP traffic to the remain alive NIC interface. we can check it use 'netstat -nr' and see that alive NIC interface's route gatway is refreshed to first level route priority. while the unpluged NIC interface's all route information disappear on route table.
while on iSCSi booting scenario, when NIC is unpluged, we do not see anything changed in route table using 'netstat -nr'. Here I am suspect that route table is stored in local file system, and when route table changes, in.routed need refresh those content in persistent store. and this lead dynamic route fail when network booting. because unplug network cable would lead root file system unreachable. while network booting need solaris' dynamic route to failover to the health NIC card to get root file system. that lead a deadlock of routing and root file system. Here could you expert guys give us some clue to find the real problem?
