How-To Dell Server : Manage Multiple Servers with OMSA and OME






This article explains the different options to manage Dell PowerEdge servers. Installation guides and advanced configuration are provided in the interactive users guides. The basic level of management is provided by the iDRAC, a controller card embedded in the motherboard. Advanced mangement options are provided at an operating system level with the OpenManage suite and SupportAssist.

Firstly, all management tools rely on the integrated Dell Remote Access Card (iDRAC). This is a management card that will simplifies server management task like provisioning, deployment, servicing, user customization, updating. The iDRAC offers a web interface to manage remotely the server. Management tools use the SNMP prootocol to communicate with the iDRAC and obtain hardware status. There are different versions of iDRAC, iDRAC 7 runs on 12G server, iDRAC 8 on 13G and iDRAC 9 on 14G.

Dell Remote Access Controller (iDRAC)

The iDRAC is a piece of hardware that sits on the server motherboard that allows Systems Administrators to update and manage Dell systems, even when the server is turned off. The iDRAC also provides both a web interface and command line interface that allows administrators to perform remote management tasks. Almost all current Dell servers have the option for an iDRAC.

Note: IDRAC functionalities are depending of the license level. More information about licensing are available in this article.

Note: An advantage of the iDRAC include being able to launch a remote console session (similar to Remote Desktop but works even when the OS is not booted up), remote reboot or power on/off your system, and map a virtual disk drive to a remote file share or OS deployment.

The Virtual Console is a very powerfull to all support maintenance operation. How to use the Virtual Media is explained in this article.

The Dell Lifecycle Controller, which is a component of the iDRAC, is another useful tool that allows for advanced functionality around updating, backing up and restoring firmware updates on your Dell Server either through a GUI or command-line interface.
Lifecycle Controller is the tool to use to deploy operating system, more information about OS Deployment in this article.

How to setup and configure the iDRAC is available on this article.
iDRAC Manuals are available on the eSupport site.

Note: For the iDRAC 8 and previous versions, the default login is user: root password: calvin . For more recent iDRAC please read this article.



OpenManage Server Administrator (OMSA)

OpenManage Server Administrator (OMSA) provides a comprehensive, one-to-one system management solution in two ways:
  • from an integrated, web browser-based graphical user interface (GUI)
  • from a command line interface (CLI) through the operating system.
Download link: Latest version is available on the OpenManage Server Administrator Download Page

Server Administrator is designed for system administrators to manage systems locally and remotely on a network.
  • Managed node: Agents and web components are installed. (Windows, Linux)
  • VIB: Agents of OMSA without web components (VMware).

When OMSA is installed without web components, you have to access this OMSA from another device where web components are installed.
User Guides are available online for more information about installation process.

Once OMSA is installed, to access the interface please enter the following URL in a navigator.

https://ServerIP:1311/

The local address is https://localhost:1311/ . It will remove most of firewall issues.
A login page will appear asking to fill the username and the password. To login use the operating system administrator credentials.

OpenManage Server Administrator is now installed and ready to be used. User Guides are available online.
