Question Solaris Problem

I have a SUnfire V120 solaris 10 machine I have recently added memory to. After installation of the RAM, powering back on, the machine did not come back on the network. Consoled into the machine, the routing table has been wiped out completely and I had to reconfigure the IP address. I got the IP address reconfigured, but I cannot add a default gateway. I keep getting network unreachable. I am unable to add routes back into the routing table.

I have changed the network cable. I have even tried on the eri1 interface (it's main configuration was on the eri0). I still got the same result.

So, I am thinking perhaps the hardware for the ethernet ports have failed on the shutdown/reboot. Is there something else I can try to get my server back online? or should I find a new server or a Solaris specific tech that can possibly troubleshoot and replace the parts that are broken?

The memory is reading find. I don't think the RAM has affected it. I just think the server is old and hardware failure. I would like to exhaust all my options before officially declaring it "dead". Smilie

Can you post output of ifconfig -aafter you have configured the IP addresses for interfaces?

# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet netmask ff000000
eri0: flags=1000851<UP,POINTOPOINT,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet --> netmask ffffff00
        ether 0:3:ba:2d:54:6a

This is what happens when i restart the network interface

# init.d/network restart
configuring IPv4 interfaces: eri0.
Hostname: unknown

hostname file is valid and working
# more hostname.eri0  lvccirt03

So i'm not sure why it's saying hostname unknown either. Definitely a strange new problem for me. Typcially resetting the network has fixed in the past. But nothing seems to be working.

After you assign as IP address, can you ping gateway?

From the out's it is showing as POINTOPOINT, so you can't expect it to be broadcasting on the network. I was in similar situation(where network was not detected, after I added additional eth's interface on a VM image)

So first check through /var/log/messages about any info on this scenario

Or simply go for reconfiguring the eri0 mate.

check through dladm show-dev for available interface..

This is b/c you are configuring the eri0 as pointopoint, check the flags:


Take a look at the configuration files,

If you want to do the configuration manually you can still do:

ifconfig eri0 unplumb
ifconfig eri0 plumb
ifconfig er0 <IP> netmask <MASK>
route add default <GW>

and it should work.

I cannot ping the gateway. if I try to add the gateway:
# route add default
add net default: gateway Network is unreachable
# ping
ICMP Host Unreachable from gateway lvccirt03 (
for icmp from lvccirt03 ( to
ICMP Host Unreachable from gateway lvccirt03 (
for icmp from lvccirt03 ( to
ICMP Host Unreachable from gateway lvccirt03 (

and for some screwed up reason, dladm is not installed on this system. I cannot use that. AND there is no /var/log/messages which i find very unusual. i'm fairly certain that pathway was there previously and on the servers it is identical to. There is definitely something unusual going on with this machine.
