I recently posted an article describing how to install Dell OpenManage on your ESXi host using the CLI command.  I have since found an update that works using an SSH connection to the server without making changes to the file.  Here are the steps I took, hope this helps.

Download the latest release of Open Manage for ESXi from http://support.dell.com

Enable remote support on the host.

1. Hit F2 and login to the host
2. Arrow down to the troubleshooting optioins
3. Make sure the Remote Tech Support (SSH) is enable
4. Make sure all of the virtual machines are shut down and put the host into maintenance mode
5. Copy the downloaded version of Dell’s open manage to a location on the datastore
   I used the vSphere client just because it was the easiest way I knew
6. Click Summary on the Host and right click on the datastore
7. Click browse datastore – you will get a new window and there you can choose to upload a file
8. Simply pick the file you want to upload and  click open
9. Open the application you will use for the SSH connection – I used Putty
10. Connect to the host using its Management IP
11. Login as root
12. type ls -a
13. cd vmfs/volumes -this will take you to the your working directory
14. ls -a This should display your datastore 
15. cd “the name of your datastore”  ex: cd datastore1
16. ls -a This should display all the files you have located on the data store
17. esxupdate –bundle “the name of the file you uploaded” update – This will start the process
    ex:  esxupdate –bundle OM-SrvAdmin-Dell-Web-6.3.0-2075.VIB-ESX41i_A00.8.zip update  
18. You should see the following occur:
    Unpacking cross_oem-dell-open.. ######################################## [100%]
    Removing packages :oem-dell-o.. ######################################## [100%]
    Installing packages :cross_oe.. ######################################## [100%]
    Running [cim-install.sh]…ok.Running [vmkmod-install.sh]…ok.Running [/sbin/esxcfg-secpolicy -p /etc/vmware/secpolicy]…ok.The update completed successfully, but the system needs to be rebooted for the changes to be effective. 
19. Reboot the host and you are done
