In one of my last articles I described the example of installing HP System Management Tools to the physical server HP ProLiant DL360 G5 with CentOS Linux 7.2. After a while, the same exact server was used as a virtualization host and the oVirt Hosted Engine components were deployed on it. The host was put into maintenance mode recently, all packages were upgraded from the online repository, including the HP tool pack installed on it.
After the installation, I decided to check the workability of the upgraded tools. I also tried to open the web page of HP System Management homepage, but I didn’t succeed, because the host was simply blocking TCP port 2381.
