    Your session, logged on as user bmoll, was forcibly disconnected on Jun 6, 2008 at 3:28:51 PM for the reason shown below:

    Connectivity to the console failed.
    Contact your support personnel to determine if your browser is configured properly to connect to the console.

    Close this window by clicking "Close".
    Any ideas why?

    Is there a certain amount of time before the disconnect or does the disconnect happen immediately after connecting?

    The disconnection happens usually after I select a server screen to view the lpars.

    Then once I reconnect I'll see the lpar screen. Then it will disconnect if I attempt to open a console window on an lpar.

    At this point I've just had to go to the physical HMC instead of remote connecting

    What URL / Port are you trying to connect to.
    Does it work from other browsers.
    Are you on the same network, are there firewalls in the way, does it work for other people.
    What version of the HMC code is this?
    Does the Java WSM app work?

    I am seeing the exact same error since our recent firewall lockdown, although
    our firewall support insists it is not related (!). He has agreed to
    troubleshoot with me, and I will share our findings. If you find an
    alternate culprit, please let me know.
    We made the following changes to the HMC network setup:
    Added a DNS domain name under the "Identification" tab
    Changed the active ethernet "destination" field to 0.0.0.0 and enabled
    routed under the "routing" tab.
    Unfortunately, these changes were not made/tested individually, so not
    sure which or even if they directly addressed the problem, as a couple
    subtle firewall changes were also made. In any case, we are once again able
    to remotely access this HMC.

    I had about the same effect, after upgrading from Version 6 to Version 7.
    The session would disconnect after some time (perhaps 10-20sec) and the
    mentioned Error Message displayed.

    In my case it was TCP Port 9960, which was not open on our Firewall. After
    opening that port things worked as they should.
    Hope this help
    Cheers Mike

    There are some recommended browser settings, have you looked at those? Here's a previous post on this topic in general:

    The documentation for HMC Version 7 says that the web browsers supported are Microsoft Internet Explorer 6.0 and later, as well as Firefox 1.5.0.6 and later. While many users have no trouble with Internet Explorer 7.0, others have reported problems. What makes the difference? Sometimes its Java code, and sometimes its the browser settings.

    For example, a customer recently reported trouble with IE 7 after he updated Java to jre 1.6.0_05 from jre 1.6.0_03. Previously, IE 7 had worked fine.

    IBM support usually will make a best-effort attempt to resolve your browser compatibility problems. But in the case above, the problem wasn't the HMC code or even IE 7 itself, since it had worked with an earlier level of Java. By being conservative in upgrading browser and Java code, you may avoid slipping into an unsupported condition.

    What are the requirements for browser support?

    1. HTML 2.0, JavaScript 1.0, Java Virtual Machine (JVM), and support for cookies. (If necessary, contact support personnel to see if your browser is configured for a Java Virtual Machine.)

    2. The browser must use HTTP 1.1 protocol; if a proxy server is used, HTTP 1.1 must be enabled for the proxy server. (In Internet Explorer, see the Advanced tab under Internet Options)

    3. For Firefox 2.0, make sure the JavaScript option to raise or lower windows and move or resize existing windows is enabled. To enable this option, go to the Content tab in the browser’s Options dialog, click Advanced... next to the Enable JavaScript option, then select Raise or lower windows and Move or resize existing windows options, then click OK to enable. These features allow you to switch easily between HMC tasks and to resize the task window.
