Dell OpenManage Server Administrator (OMSA) is a systems management tool you would typically install on any of your Dell servers. You can use the same functionality on your Dell servers acting as VMware hypervisors.

First we’ll need to obtain the Dell OMSA vSphere installation bundle for ESXi 5.5. Depending on the version (build) of ESXi you are using you’ll need to get either version 7.3.0.2 or 7.4. If you are running ESXi 5.5 Update 1 or newer you want to go with the 7.4 installation bundle, otherwise use version 7.3.0.2.

You can find out what is the build number you are running, by clicking on your hypervisor in vSphere client.

You can consult the list of ESXi builds below to determine your patch level.

In order to proceed, the host (hypervisor) will need to be placed in Maintenance Mode. If this is your production host, you are probably going to want to vMotion virtual machines away from this host or turn them off prior to putting the host in maintenance mode.

In VMware vSphere client, select the appropriate host, then right click on it and select the Enter Maintenance Mode menu option.

Next, we’ll need to make sure that SSH is enabled on the host so that we can access it from our workstation. More information on how to enable SSH on an ESXi host can be found here.

Connect to the host via SSH. You can use a tool like Putty to do so. When prompted enter in credentials with sufficient privileges to access the host via secure shell.

If you have an older version of OpenManage already installed you may want to uninstall it prior to installing the newest version. You can verify what is installed using the following command:

esxcli software vib list

image

To remove the older version of software run the following command:

esxcli software vib remove –vibname=OpenManage

In our case example, we’re installing OMSA for the first time, so when we run the command show above we receive an error.

Next step in the process is to upload the (installation bundle) file you have previously downloaded to a datastore that is accessible by your host. In the vSphere client, select the host, then click on the Configuration tab and select Storage in the Hardware section on the left. Select the datastore (on the right) with sufficient free space available. Right click on it and click on Browse Datastore.

image

In the Datastore Browser window that comes up, click on the Upload files to this datastore button, then select Upload File and browse to where you have downloaded the OM-SrvAdmin-Dell-Web-7.4.0-876.VIB-ESX55i_A00.zip file. Click Open.

image

Once completed successfully you’ll see the .zip file listed in the datastore.

image

Alternatively you can use a tool such as WinSCP to upload the .zip archive to the VMware host.

Now that the file has been uploaded to the datastore, we need to move it (or copy if you want to reuse it for installation on multiple hosts) to the /tmp/ directory on the local file system of the host. We can do so by issuing the command displayed below.

mv /vmfs/volumes/Datastore/OM-SrvAdmin-Dell-Web-7.4.0-876.VIB-ESX55i_A00.zip /tmp/

image

You can confirm that the file has been successfully moved to the /tmp directory by typing:

ls /tmp

image

Now we’ll install the vSpere Installation Bundle (VIB). Type the following:

esxcli software vib install –d /tmp/OM-SrvAdmin-Dell-Web-7.4.0-876.VIB-ESX55i_A00.zip

image

Please note the message stating that the update has been completed successfully and that a host reboot is required in order for the changes to take effect.

In the vSphere client, right click on the host and select Reboot. Once the host comes back up, and reconnects to the client, right click on it and select Exit Maintenance Mode.

The VMware host should now be accessible from the Dell OpenManage Server Administrator web console. If you don’t have it installed on a (management) machine already, you can get the installation packages (x86) here and (x64) here.

Use your web browser to navigate to port 1311 on the machine you have OMSA installed on (I.e. https://server:1311).

This will log you into OMSA concole for that particular server. Click on Log Out in the upper right. Click on Manage Remote Node link in the bottom of the page.

Specify the hostname/IP address of your VMware host and the appropriate credentials then press the Submit button to access Dell OpenManage Server Administrator for the ESXi host.
