iLO 3 and hung Active Sessions

Hello All,

 

I am having problems with several of my servers holding on to iLO sessions.  I am running iLO 3 with firmware 1.28 (which is current on the HP iLO site).

 

What is happening is if there is a communication issue and the session drops, the next time the user goes in, it may not connect to their previous session.  I currently have one server with 2 hung sessions and one server where the iLO has stopped responding to browser requests. (Had shown 4 hung sessions last week.)

 

Besides pulling all power on the servers (as these are several continents away), how else can the session s be cleared?


Thank you in advance for your help.

Re: iLO 3 and hung Active Sessions

There are a couple of ways to reset iLO without pulling server power (as long as you can still access the iLO)

 

if you can still access the browser interface, under the diagnostics tab there is a button to reset iLO.

 

You can also SSH to iLO and run the follwoing command at the iLO prompt

 

reset /map1

Re: iLO 3 and hung Active Sessions

Jimmy,

 

Thank you for the information.  It did work for the servers that I could still browse to.  I still have one that is not responding to port 80 or 22, but I can ping the IP.  (I do know this is an iLO because only iLOs connected to VLAN.)

 

Is there any option through Redhat Linux (5.8) to perform the same item?

 

Thank you for the follow up.

Also,

 

Using VLAN means that you are using iLO shared network port. Can you please tell us what server model is this?

Re: iLO 3 and hung Active Sessions

Hi,

 

Another way to reset the iLO 3 within Linux is using HPONCFG utility.

 

hope this helps,

Re: iLO 3 and hung Active Sessions

Hi Aftab,

 

I have been trying that.  This is 64-bit Linux, the HPONCFG utility is 32-bit.  I have been unable to find the libcpq.so.2 library file for HPONCFG.  The HP insight driver is 64-bit and has the libcpq64.so.3 library. (Doing this from memory as I am not in the office right now.)

 

Thanks for the help.

Re: iLO 3 and hung Active Sessions

Hi Oscar,

 

This is a DL580.  To update everyone, we were able to shut down the server and pull the power for 5 minutes.  When we replaced the power cords, we still had the same problem.  The iLO3 is still not responding to port 80.  I can ping the IP address.

 

The server was restarted (manual power button) and is running again.

 

I am a little lost as to why this did not clear the sessions.  I am running under the assumption I am not a victim of an iLO going bad while I was traveling back from doing the installation.

 

Thank you for all the suggestions.

Re: iLO 3 and hung Active Sessions

Hi,

 

You may login to www.hp.com/support/ilo3

 

Select the Operating System as Linux 64 bit and download the utility. Select HP Lights-Out Online Configuration Utility for Linux and download

 

Please check the installation instruction

Prerequisites:
This utility requires the following minimum firmware revisions: 

  • Integrated Lights-Out 2 firmware v1.00 or later
  • Integrated Lights-Out 3 firmware v1.00 or later
  • Integrated Lights-Out 4 firmware v1.00 or later

The management interface driver and management agents must be installed on the server.

 

Hope this helps,

Re: iLO 3 and hung Active Sessions

Hi Oscar,

 

Tried ipmitool.  Did not work.  Can ping but not open it through the browser.

 

I am trying to fix my hponcfg issue and will try reseting it that way.

 

Thanks for the help.

Re: iLO 3 and hung Active Sessions

If you pulled power to reset and the iLO is still unresponsive I'd think it is one of 2 things. Either the iLO itself is bad, or maybe something else on the network is set to the same IP address. Pull the network cable from iLO and see if you can still ping the IP.

Re: iLO 3 and hung Active Sessions

Are you trying to connect to iLO webGUI from a remote PC or from the same server?
if you are using iLO Shared Network Port, there is a known limitation where you cannot access iLO from the same server's shared NIC.

Re: iLO 3 and hung Active Sessions

Jimmy,

 

I think you are on the same path I am now.

 

I can ping the IP.  I can also see the iLO configuration using the HPONCFG (finally got that working).

 

As the servers are remote to me (several K miles) I am trying to get resources available locally to perform these additional tests.  Plug into the iLO port with a laptop and open the port through IE.  If it does not work, then something went wrong in the controller.

 

There sould not be another host with the same IP as this VLAN was implemented specifically for these servers.  I can see all the other iLOs assigned to this subnet.

 

I do have staff looking at if there was any "fat fingering" with the implementation of the ACL for the subnet.

 

I will let everyone know what I find.  May be another week. (Please nothing go wrong.  Please nothing go wrong.)

Re: iLO 3 and hung Active Sessions

Hi Oscar,

It is from a remote server. I am a few (K) miles away from it. I am down to one of 3 options: Duplicate IP (Jimmy's suggestion, but it should not be), network/acl mis-configuration, port controller went bad.

Thank you for continuing to provide suggestions.

Re: iLO 3 and hung Active Sessions

If you can use hponcfg to talk to the iLO, then send it some XML to set the IP to something else temporarily to get the dup IP thought out of the equation.

Re: iLO 3 and hung Active Sessions

Hi Jimmy,

 

Thank you for the script.  We were finally able to determine the issue.

 

We did send a tech to the remote location who confirmed the iLO was working fine because they were able to plug directly in to the port and get the welcome screen.

 

There was a firewall rule that was put in wrong.  The subnet was one digit too high.  We had ruled this out because we could get to the iLO which was on the broadcast address.  We were expecting both the broadcast IP and next network IP to fail.  Chalk it up to experience.

 

Lesson learned... You can put a host on a broadcast address and have it work.

 

Thank you all for your help.
