This is a part which the Unix guys don’t like. Therefore we’ve deployed the agent without the root password.

Willemjan van Laarhoven wrote a great post on how to install SCOM Unix Agent without having the root password.

When you try to deploy a SCOM agent on a Linux Operating System (most of the time a Virtual Machine) is possible that you get Failed to get random data – not enough entropy error message.

The message in details :

Now, fixing the issue:

  • clean off the partially installed agent using the commands

  1. rpm -e scx
  2. rm -rf /etc/opt/microsoft/scx
  • Regenerate the random element
  1. rm /dev/random
  2. mknod -m 644 /dev/random c 1 9
  3. chown root:root /dev/random
  • Rediscover the server from the SCOM Console and install the Agent
  • After fixing the install issue, switch the /dev/random file back to a signed random file using the commands:

  1. rm /dev/random
  2. mknod -m 644 /dev/random c 1 8
  3. chown root:root /dev/random
