PXE OSIM not works

  • 1.  PXE OSIM not works

    Posted 12-11-2017 10:35 AM

    Hello friends I'm going through a very interesting problem, though, it's ending my quiet nights sleep. In my CA Client Automation environment, I have multiple VLANs for Desktops and Notebooks (altogether more than 20 VLANs). However, I have only 4 scalabilities to fit the entire structure. When the OSIM process starts, the machines do not appear in the OS Installation option. I installed WireShark in one of my Scalabilities and set the bootserver option for this SS. In WireShark, I see the packets coming to the server, but I can not perform the installation. Nothing appears Has anyone ever been through it or seen anything like it? I already opened a ticket in support, but I could not move because of other problems and I asked to close

    You need to configure the iphelper on your router.  Here is an example from Cisco.

    Hello Richard, how are you? I already have an IP Helper configured. I have a doubt. In my development environment, I have no DHCP option informing the boot file. I have read in some articles that I need to declare within DHCP a boot file option. Where do I find this file? Which way?

    Please check the SS configuration policy and make sure that use ACL and Disable PXE are set correctly

    +1 Agree.

     

    I set a policy to my SS so

    /DSM/Scalability Server/OSIM/ManagedPC/Server/Use answer control list = 0

    /DSM/Scalability Server/OSIM/ManagedPC/Server/Disable PXE service at start = False

     

    The PXE server by default doesn't answer the 1st un-managed PXE boot requests the ACL to 0 setting ensures answers on 1st PXE boot.  Otherwise a few PXE boots to register the MACs.

     

    Also check status of your SS boot server under 

    /Control Panel/Scalability Servers/All Scalability Servers (properties) if your boot server state is not active or not answering PXE requests will show that status.

    Hi mtreichler. I checked my policies and they are all as you informed. My SS is responding normally, but I have no answer. The error you present at the client is: PXE-E55 ProxyDHCP Did Not Reply To Request On Port 4011

    I'd double check your IP Helper setup.  We typically have 2 helpers setup, 1st helper for DHCP, 2nd helper for PXE from DSM.  Screenshot of what PXE looks like when working.

     

    10.190.100.39 is PXE client

    10.190.100.1 is DHCP

    10.190.100.2 is DSM-SS

    Thanks for the tip, I'll ask for a screenshot of the IP Helper configuration for the Network / Security team.
