New install with network issues

[Stephanie L Davenport]

I have a newly installed server that won't connect to the network.

I have checked all my settings and everything looks correct.

Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/0/0/0 0x00306E485512 0 UP lan0 snap0 1 ETHER Yes 119

# ifconfig lan0
lan0: flags=843
inet 40.2.217.17 netmask ffffff00 broadcast 40.2.217.255

# lanadmin -x 0
Current Config = NO LINK AUTONEG


But, every time I go into SAM to look at the configs... I get an error about the nic card not being installed and then it basically locks up.

lanadmin shows a no link.So check the cable first.
Also check whether MAC level communication using 'linkloop' is happening with the other network cards in the same subnet/vlan.

Shalom,

I suspect hardware failure in this case.

Use cstm,mstm, or xstm to test the NIC.

Also try a different cat 5 cable and check the network switch and lights on the NIC card itself.

I just found out that they want to set this to 1000FD instead of 100FD. As far as I can tell, it is not supported with this hardware.

Also, I am not getting a link light. So, I have a feeling that this is a combination of an unsupported "speed" and a connection that has been dropped from inactivity.

Stephanie,

What model server and what sort of network card? If this is really a "new install" it should be capable of 1000BaseT - all the systems we currently sell come with 1000BaseT LAN connections.

Post output of:

ioscan -funC lan

It is impossible to set a NIC to a speed that it is incapable of running. You need to look at the card or the card's model number to see what speed it supports. Hint: ioscan -knfC lan

Autonegotiation is the preferred method for all NICs, but required for 1000Mbit cards. However, it will never negotiate anything if the link is down. If there is no light next to the LAN cable, then the link is dead. This could easily be due to a disabled switch port. Move a working cable to the questionable port -- no light = dead port.

> just found out that they want to set this to 1000FD instead of 100FD. As far as I can tell, it is not supported with this hardware.

"THEY" can buy you a card that supports 1000Mbit. Don't force a card's speed unless autonegotiation fails (occasionally happens with 100Mbit, never with 1000Mbit or 10Mbit unless the cable is far too long). Post the output of ioscan so we can see the hardware model:

ioscan -knfC lan

No light = not connected. Not much to figure out here.

This is already at "autoneg", you will have to configure your link partner(link at the other side) to autoneg. This could solve your problem.

Hi,

Did you find any error message in /var/adm/syslog/syslog.log file.

If your NIC card goes bad then you will get some error message in your syslog.log file.

GbE should "ALWAYS" be left on autoneg. It is a required part of the IEEE standards. Sorrow and woe will be the result when you start trying to hardcode GbE NICs...
