Hi All,

In one HP server the primary network ip was not reachable. After reset the lan Interface through lanadmin command it working properly.
But this issue is occurring frequently.

Can any one help me to fix this issue permanently?

Thanks
Sujith

sujith,

Also check network cable and switch ports where cable is connected.

Take help from network admin guy.

Have you recently applied any patch or bundle to this box?

provide:

lsdev -C lan
netstat -in
lanscan

output

Shalom,

Check your /dev/ip/ ip_ire_status. If it's set to 1 your host is probing your gateway usin ICMP protocol. If the gateway block ICMP traffic, after some probes the route is marked as dead and so out-of-use. You can set ip_ire_gw_probe parameter to 0

# ndd -set /dev/ip ip_ire_gw_probe 0

to override this.
