Working onsite today with one of my clients, they have a large number of servers across multiple sites. One of the clients IT team asked me why two of their servers were displaying a very strange and empty page for the HP Power Manager console. The HP Power Manager console is a web based interface that runs on the server and displays all the relevant information and normally has a login before you get to it. On the affected servers however it goes straight to the page below.
Some investigation into this showed me that it was a devmanbe.exe process that was the actual web server. Not knowing anything about that webserver meant we had to figure it out on the fly. I noticed that in the folder where devmanbe.exe was, there was a devmanbe.ini file as well. I opened up the devmanbe.ini file on the affected system and found it’s contents as below. When I compared it to the working system, I realised that the working systems file was 2k in size but the problem system was only 1K. I copied portions of the broken file into the good file, restarted the HP Power Manager service.
Once the service was restarted, I connected to the website, got the proper login prompt and was then able to see everything as planned. I’m still not clear why it truncated the file in the way it did, or if it will happen again.
