Topic: Server config bios ILO

[smnirosh]

We have hp pro liant server. We we boot the server the ILOv 4 unknown. We had set ILO to dhcp enebled. It won't get the dhcp ip from router. We can go internet from mobiles connected to router.
But with server it connects to the internet 2or3 mins. How to isolate this problem.

I have reset router but no good results

[Stefano]

please, give us as much details as you can, since we need to understand exactly what's going on  to help you

[smnirosh]

We use HP proliant server. When i come to office today morning the users of our network have no internet. Then i checked that server cannot ping to google.com. I resterted the server. In booting process it shows me iLO 4 IP unknown. Previously this is set to 192.168.1.6.
I reset router. Ok the server got  the address again.
But after 5 minuts again no internet. ILO 4 IP  unlnown.
Every time i restart the server it is ok. But few munites later it is going wild

[Stefano]

well, you'd read the manual of your server.. IMO, if you don't need ILO (AFAIK you need to buy a license to use it) you can safely disable it from bios

[smnirosh]

What?????  Do i need licence. Until today it worked well. Why today licence matter?

[Stefano]

AFAIK, ILO works in a "basic" mode without license.. to enable/use some features you need an additional license..

BTW, it seems to me an HW issue, not a SME one.. you'd better call your hw supplier or ask directly to HP

[smnirosh]

Ok. Lets say we have no internet. But why cannot access server shared folders also?

[Stefano]

Smnirosh, I don't know anything about your lan setup, I know you're running a SME server, a NS server, virtual machines.. but, again, I (we) don't know anything..

I'd suggest you to enter the bios, configure ILO to use a fixed ip, decide WHO is the dhcp server in your lan (SME server, router, whatever) and configure all accordingly..

IMO, this is no a linux/SME issue and (as you've been already told) you'd hire a consultant to setup your infrastructure
don't get me wrong but  it seems to me you're lacking some required knowledge

[DanB35]

I'm not understanding the issue.  It appears that ILO is some sort of out-of-band system management interface, somewhat like IPMI on my SuperMicro server.  But it sounds like you're saying your internet connection isn't working.  How are those two things related?

[smnirosh]

Yes this thing is very strange. I disabled the iLO. But the problem remains unchanged.
I am currently not running any other server on office network except smb dc, dhcp , openvpn bridge and gatewayin the server. Other nethserver is not mixed with office lan. That one is our of LAN. And virtual server is running on the vmware 10 by NAT mode making sure not mixing up with office LAN.
 I don't know what to refer and what to do to this issue. But as stefano said to me, i disabled iLO. OK. but i feel something strange.

[Stefano]

We had set ILO to dhcp enebled. It won't get the dhcp ip from router. We can go internet from mobiles connected to router.

so it seems you have dhcp enabled on your router.. is it so? is dhcp enabled on SME too?

[smnirosh]

Yes to both questions

[smnirosh]

Enabled only for clients to get ip

[Stefano]

that's bad and wrong.. having 2 dhcp server on the same lan will likely cause misconfiguration and strange behaviour..

choose one of them and shut down the other.. you have no reason to have 2 dhcp servers

[smnirosh]

The server has two network cards. Then the router is enabled dhcp, but to wan ip of server is static. 192.168.1.2. Then the lan ip of server is 192.168.100.100. Also static. Directly connected this ip for switch. Thus sme server is dhcp server for pcs connected to switch. No problem. Until yesterday it works fine.

[Stefano]

smnirosh: if your server is in server and gateway mode and you have 2 dhcp servers (SME itself and router) but in different subnets, there's no problem.. BTW, you MUST be clearer wher you answer to questions..

we don't know anything about your setup, so BEFORE asking, you'd tell us how thigs are configured..

that said, I don't know why you're having this kind of issue, but in any case ILO should have a fixed IP, and you should configure it via bios.
I guess your server has only 2 nics, so one of them is working/can work in "shared" mode, i.e. as ILO interface and like a norlam nic.. is it so? did you read the user manual?
did you search in HP's support site for info? and with google?

[smnirosh]

Little bit hp usermanual. But not any sources.  Contribs is the first source. Ok i will go to hp support because in this case is more strange also to me not only you. All the thing i hears is not good. Let's check tomorrow.  TC

Let's at least clarify what's going on.  Here's what it sounds like to me (though we shouldn't need to be guessing):

Your problem is that clients to your SME server can't connect to the Internet.

Your Internet connection comes into a router (a wireless router, perhaps?), which serves DHCP to its clients.  The WAN port of your SME server (in server/gateway mode) is connected to the/a LAN port on the router.  Your ILO service either shares the WAN port, or has a separate port which is also connected to the router.  The LAN port of your SME server is connected to one or more client machines through one or more switches, and provides DHCP service to those clients.

Is this correct so far?  If so, I'm pretty confident that the ILO issue is a red herring (i.e., it is not causing the lack of Internet access), though it may have the same cause.

Here are some troubleshooting questions:

• What are the IP address and subnet mask for the LAN side of your router?
• From the SME server, can you ping the router?
• From one of the SME server's clients, can you ping the router?

[smnirosh]

Your problem is that clients to your SME server can't connect to the Internet. yes also shared folders of eachothers'

Your Internet connection comes into a router (a wireless router), which serves DHCP to its clients.  The WAN port of your SME server (in server/gateway mode) is connected to the/a LAN port on the router.  Your ILO service either shares the WAN port, or has a separate port which is also connected to the router.  The LAN port of your SME server is connected to one or more client machines through one or more switches, and provides DHCP service to those clients. - Correct, but there are two ports eth1 and eth2 plus iLO port. But that iLO port is covered by hp and we cannot plug any jacks in it.

Here are some troubleshooting questions:

- 192.168.1.0/24

• From the SME server, can you ping the router?

- yes

• From one of the SME server's clients, can you ping the router?

- no. (host cannot reachable) .

ILO and SME Server? Two different worlds to me (and I do host on a HP server). Simply put, do not use ILO.
