LOM – Lights Out Management 10.5.3 – Network Status always “Down”

[samoir]

Hi there
Im running an Intel XServe 2008, 10.5.3, and have it setup utilising dual ethernet ports and LOM.
On my local Mac Pro im using Server Admin Tools (10.5.3) as the management interface, and also Terminal sometimes.

Everything works fine, with Server Monitor and Server Admin, EXCEPT FOR ONE THING : Under the Network tab of Server Monitor the “Link Status” is always stated as “Down”, even though the server is transmitting and receiving perfectly normally.

Eth0 is used for the primary machine IP, LOM is running on Port2 using a unique LOM IP for the machine.

Does anyone know why the link status shows down all the time??? It seems a minor but fairly annoying “glitch” given the machine is working normally, id rather this information is accurate. Id be greatful if anyone could help.

thanks in advance, samoir

Hi there,

I am having an identical issue with an Intel XServe 2008, now running 10.5.4.

Dual Ethernet – eth0 Primary | eth1 LOM

Machine appears to function perfectly, aside from the same glitch that samoir has mentioned.

Somoir – is this still an issue for you or did you find a resolution?

Cheers,

W

no relief yet, i still have the same issue, even after upgrading to 10.5.4 : Link Status: Down

Seems really weird as using Server Admin its polling the Network throughput, but Server Monitor seems like everything else is correct except for this on the Network Tab.

Frustrating.

I have two new Intel Xserve 2008 models. I do not have dual ethernet ports setup. I read here or on Apple Discussions that having two ethernet ports configured each with their own IP address in the same subnet would reduce performance? I was looking on Friday for this information to see if I read that right. Anyway, I’m interested in trying this out. I am a Cisco shop and found that Cisco’s LACP (link aggregation protocol) was a little different than I thought it work…are you running your Xserves on Cisco switches? Another annoying glitch — at least I think it’s a glitch — is that Server Monitor shows “Invalid user name or password” on the Xserve itself using localhost or 127.0.0.1. If I use Server Monitor on another server with the Xserve’s lights out IP address, it give me the status no problem. Strange!

hi
Our setup is not via a Cisco router.
However we are using dual ethernet ports, one for network connectivity (en0), one for LOM (en1)
The 1st IP, the actual IP of the machine (en0) is on 210.XXX.111.XXX, subnet 255.255.255.224, etc.
The 2nd IP, for LOM (en1), on a different subnet and IP range, as 192.168.XXX.XXX, under 255.255.255.0

You might find the above useful, i dont know.
this was what i understood to be the best configuration for LOM, as there would be conflicts if done any other way.

On different sources I’ve read that unplugging the power from the xserve for about 30 seconds will reset the LOM chip and solve any LOM related issues.
Please note that you will have to shutdown the server before unplugging the power leads and you will have to setup LOM under server monitor again.

😮

Has this been resolved? I am seeing this too. Does the unplug/reset work? and is it the only way?

Thanks.

LOM on the Xserves uses a specific port that needs to be open for it to work.

623 UDP Lights-Out-Monitoring – Used by Intel Xserves’ Lights-Out-Monitoring (LOM)

@tlarkin – LOM is working. THe post is about the Network Status being incorrect, (the error is being viewed by Server Admin Tools interfaces – and everything else is working as it should, apart form the network interfaces error.)

[samoir]

The network interfaces error has been fixed now. Both show as “UP”.

Well at least after applying the software update. My system is running the following at both ethernet interfaces show as up:
OS X Server 10.5.7, XServer LOM Firmware Update 1.2, and using Server Admins Tools 10.5.7
