After Charles help getting Dell support to assist on this they pointed out a problem with the VMware update service trying to use a proxy for reaching the Open Manage appliance.  It was only calling this service when trying to convert the cluster to image based updates, so the plugin itself was generally all functioning properly until trying to use it in this manner. To check for this problem view the log file, /var/log/vmware/vmware-updatemgr/vum-server/  “hsm-service.log” For type type of error, [ERROR] Failed to establish connection: HTTPSConnectionPool(host='IP Address of dell open manage here', port=443): Max retries exceeded with url: /omevv/GatewayService/v1/vsphere-lcm/hw-support/v1/packages (Caused by ProxyError('Cannot connect to proxy.', ConnectionResetError(104, 'Connection reset by peer'))).   If you are using a proxy with vCenter the config file is located at: /etc/sysconfig/proxy  There is a section labeled NO_PROXY you can add the ip/hostname of the Dell Open Manage appliance to.  After making this change, rebooting vCenter, I am now able to see the baseline I created when trying to convert the cluster to using image based updates.   Dell support was extremely helpful in diagnosing this issue, and I was at a complete dead end without their assistance.
It seems to be basically this issue,[URL]   I'm using the 1.01 OMEVV solution, my host all have the advanced+ license installed on them and show as healthy etc directly in the plugin.  I have created a baseline profile from the Dell Default Catalog and have applied it to a test cluster with just two host in it.  I applied the OS Driver pack to the cluster directly via the plugin and it worked as expected.   I would like to switch the cluster I am working with over to the image based patching and included the Dell Firmware option which was my primary reason for purchasing the Advanced+ licenses.  When I go to add the Firmware options it shows OMEVV in the dropdown which I can select, it then spins for a bit and shows no options in the "Select Firmware and Driver addon" section.  I've deleted and recreated the baseline profile a few times and have never been able to get any options to show up here.  I have called support and was told I did not have software support on my systems, although I do have the proper licenses to use the software. Researching online I can't find much on the specific steps to take to get this working, it all seems to point to documents and videos on the older version of the tool, but as far as I can tell I am doing everything correctly and it should be showing me the baseline I created for the cluster I am trying to switch to image based patching.   When managing systems via OpenManage directly I had to put in the idrac l/p for each system which made sense for it to work with the systems, but in the vCenter plugin I never had to enter any of that information in.  I assume it is somehow able to update things without needing that information from the plugin?   Any help or direction is appreciated as I can't really go back and ask for more money on something that I haven't been able to get to work.
