DataDomain Enterprise Manager (DDEM) or System Manager graphical user interface (GUI) is not accessible after upgrading to DDOS 5.7.3.0 or DDOS 6.0.0.x

Environment:

Data Domain

Data Domain Management Center

DD OS 5.7

DD OS 6.0

Description:

Data Domain Restorers (DDRs) provide a web based graphical user interface (GUI) known as Enterprise Manager and/or System Manager which can be used to manage the system.Due to changes and updates in the Data Domain Operating System configuration and bundled software on DDOS 5.7.3.0 and DDOS 6.0.0.x the GUI can fail to function as expected following an upgrade to these releases. On affected systems, attempting to connect to the GUI will cause a 404 error to be displayed in the web browser.

Resolution:

This issue only exists on DDRs which were initially installed with DDOS 5.2.x (or earlier) and have subsequently been upgraded to DDOS 5.7.3.0 or DDOS 6.0.0.x. To determine the version of DDOS which was initially installed the 'system upgrade history' command should be used as shown below:

# system upgrade history

Version          Partition   State     Time
                 Number
--------------   ---------   -------   -----------------
5.1.0.1-246426   1           INSTALL   06/27/11 03:11:51 <=== NOTE
5.1.0.3-249977   2           UPGRADE   07/07/11 21:59:17
5.1.0.4-259167   1           UPGRADE   08/25/11 20:59:24

In the above example the DDR was initially installed with DDOS 5.1.0.1 so is vulnerable to this issue. The solution is to re-generate the certificates.
