OpenManage Essentials - iDRAC or CMC displays an “unknown” status after upgrading to 2.40.40.40 or later
概要: Solution for the OME - iDRAC or CMC displays an “unknown” status issue after upgrading to 2.40.40.40 or later
文書の内容
現象
It has been observed that after upgrading to the latest firmware version (iDRAC >= 2.40.40.40, M1000e CMC >= 5.2, FX2 CMC >= 1.4, VRTX CMC >= 2.2), the iDRAC, or CMC displays an "unknown" status.
The latest firmware version supports TLS 1.1 as the default communication protocol. If the browser or operating system where OpenManage Essentials is installed, does not support TLS 1.1 protocol, then the device displays an "unknown" status.
Solution
To resolve this issue, please check that your navigator has TLS 1.1 & 1.2 enabled. Details on how to enable TSL 1.1 and 1.2 is explained in "Step 2: Preparation for Enabling TLS 1.1/1.2" in the following KB article Disabling TLS 1.0Alternatively, if the navigator is updated to a recent version. For example IE11, TLS 1.1 and TLS 1.2 will natively be activated and the issue will disappear.
Note: Ensure that the required registry updates are done either manually or using the "Easy Fix." Described in the Microsoft support article - "Update to enable TLS 1.1 and TLS 1.2 as a default secure protocols in WinHTTP in Windows"
