Access to ODA ILOM is challenging ?

TIP 117#: Access to ODA ILOM is challenging ?

New ODA is configured with ILOM IPs and network cable is plugged to Netmgt port. Everything is ready for connecting to the server via ILOM and bummer!, you may see the whole connection or at least the connection to remote console does not work as it is expected.

The following item could come handy to troubleshoot and fix the issue:

ILOM client requirements:

Per the following link, the client access should meet certain requirement.

I found that having right Java and registering it in browser are the key.
For new ODA (X5-2), per 888888.1, consider upgrading Java to 7 to avoid bug 20420055

After you make all necessary changes per above requirement, you may still have some problem connecting to remote console.
The following two issues are reported on several customers which we have :

Issue : ILOM remote console is blocked by rule set 

Solution : The simplest solution is to remove rule set file - The file is C:\Windows\Sun\Java\Deployment\DeploymentRuleSet.jar and it is not dependent on where Java is installed.
If the issue still stays, consider setting Java security level to medium in Java control panel (in windows in Windows control panel)

Issue : ILOM remote console errors out with "Video redirection error - no appropriate protocol found"

Solution: Comment out jdk.tls.disabledAlgorithms=SSLv3 in JAVA_folder/lib/security/java.security and restart the browser
