How are you patching the host(s)? From the command line using esxcli, or using VUM? In both cases you should be able to update the newer build with the Dell Offline Bundle.
From the command line run e.g.
esxcli software profile update -d /some-location/bundle.zip -p profilename --dry-run
(Note: --dry-run will shw you what's going to happen, without actually doing anything)
Using VUM, upload the offline bundle to VUM, and add its contents to your update baseline, which already includes the latest installed patches.
I typically just use ISO to install the Dell Image. In between, I use vCenter update manager.
I'm not sure about the interactive update, so I can't tell you what will happen. However, I assume it will just update - i.e. not downgrade - installed components.
Which Dell image did you use the last time? Was it already an Update 3 image?
What may be an option for now is to check what the update will do.
To do this (this can be done online with the VMs powered on):
- download the appropriate Dell Offline Bundle (.zip file)
- upload it to a folder on a datastore
- run the following commands from the ESXi host's command line
esxcli software sources profile list -d /vmfs/volumes/datastore/folder/offline-bundle.zip
esxcli software profile update -d /vmfs/volumes/datastore/folder/offline-bundle.zip -p <profilename> --dry-run
Based on the last command's output, you can then decide whether you want to command again without the "--dry-run" option, followed by the "reboot" command if the update succeeded.
Running the command without "--dry-run" will of course require that the VMs have been shut down.
Edited: Changed "install" to "update" for the esxcli command!
Hi yes, it was the previous released Dell Update 3 image from February. I will run those commands and see what happens.
I guess my bigger question here is what is the correct way to be doing this? Dell takes so long to upgrade and release images, and when critical updates come out, from a compliance perspective, we cannot just ignore them and wait 4 month for Dell. Is it wrong that we are patching in between Dell releasing their images? Thanks.
you're on 6.7.0 Update 3 (Build 16713306) and want do downgrade to 16075168 by using a Dell Custom ISO?
Is it wrong that we are patching in between Dell releasing their images?
Not at all. Vendors usually support VMware patches within the same "Update" version, which shouldn't cause any issues.
So with the commands I provided, the most that should show up as to be installed may be some vendor specific add-ons/drivers (if any at all).
Ah ha...so it should be "smart enough" to see that I have the more current versions in place and only update what is needed - the drivers.
Yes, that's how it works.
Important: Please note that I accidentally posted the wrong command line option in my previous reply ("install" instead of "update"). I just modified this!
It is not that I want to downgrade, but Dell is always behind when they release their images with updated drivers.
Thank you Andre. Much appreciated.
