Data Domain Web GUI (Interface ) Not working Post upgrade to 5.7
Hello ,
We recently upgraded the DD OS from 5.5 to 5.7 and it normally has 12 phase and the reboot is the last phase of the upgrade and the system reboot completed and SSH was accessible but the upgrade screen that is still showing as reboot phase in progress was accidentally closed and as a result WebGUI is not working while all other things work normally . We did 2 upgrades simultaneously out of which the other system where the screen was not closed completed the reboot phase in the web screen automatically and prompted the login screen whereas for the problematic one whose upgrade screen accidentally closed has issues and it did not work even after the second clean reboot and below is the error ,
HTTP Status 404 - /ddem
type Status report
message/ddem
descriptionThe requested resource is not available.
Apache Tomcat/7.0.53
I am planning to perform a shutdown and then power on the DD manually to see if this gets sorted out but before that i would also like to check if anyone had similar experiences and a way how that was sorted out ?
Thank you and it looks like the issue is exactly the one you highlighted, unfortunately the version is 5.7.3.0 so the workaround cannot be applied as it is applicable only for DD OS 6.X . I will raise a case with DellEMC and let you know what is done in order to sort this out .
EMC has confirmed that the same steps can be executed in DD OS 5.7 also and when i did that all went fine and issues solved . thank you for the article .
We had this same problem after upgrading to DDOS 5.7.3.0. Problem lies in self-signed cert. It no longer worked on 2 of our 4 systems. Regenerating the cert as described in the technote resolved the problem.
