Dell VMWare ESXi 5.5

Download the “Dell OpenManage Offline Bundle and VIB for ESXi” from Dell. It’s a ZIP file. Don’t extract it.
Using FileZilla or an SCP client, upload it to /tmp on the ESXi server.

Using VMware vSphere Client, put the server in Maintenance mode.
Log in to SSH (using PuTTY) and run the following commands.

One installs the VIB, and the other enables SNMP (obviously change ‘public’ which is the community name):

# esxcli software vib install -d /tmp/
# esxcli system snmp set --communities=public --enable=yes

Now reboot the server. Exit maintenance mode.
Create and install a Windows Virtual Machine (2003, 2008, 2012, whatever, as long as it’s 64-bit). It could also be a real physical server, maybe running Linux. For the Windows VM case, download and install DELL OpenManage Server Administrator Managed Node. It will complain about not having real Dell hardware and that it will only install the webserver. That is exactly what we want. Hit on the machine you installed the managed node, accept the certificate warning, then input the ESXi server’s IP address and username/password, and check ‘ignore certificate’.

Enjoy full OMSA management.
