Oracle recently released an update to Java7 that may impact any DRAC5, iDRAC6 or iDRAC7 Enterprise features that use Java, such as Virtual Console and Virtual Media. Users who have upgraded their Oracle Java installation to 7u45 or higher (possibly by allowing auto-updates to occur) may receive an additional warning message when launching these features.
This message is a notification only. If this message is received, click "Run" to continue to launch the Virtual Console or Virtual Media viewer (optionally, with the “Do not show this again…” box checked).
Alternately, restoring the previous Java version would also prevent the display of the message. Please refer to the Oracle Java documentation on how to uninstall Java. After uninstalling, re-install Java 7 update 21 (or your preferred version).
Dell is working to provide a release of iDRAC firmware to resolve this issue and make it compatible with this and other upcoming Java7 upgrades.
