How to remove hosts from inventory

[chrischrischris]

Hi all,

I need to remove hosts from inventory and am unable to.   I'm stuck removing them from the vSwitch.

I generate an array of hosts like this:

$HOSTS = get-vmhost | Where-Object {($_.Name -like '*26*') -or ($_.Name -like '*27*') -or ($_.Name -like '*28*') -or ($_.Name -like '*29*') -or ($_.Name -like '*43*')}

But I'm unable to figure out how to remove them from the distributed switch and then from inventory.

Any help would be appreciated.

Did you try the Remove-VDSwitchVMHost cmdlet?

Hi Luc,

I'm not sure what the problem is, but that cmdlet does not exist for me:

Remove-VDSwitchHost Remove-VDSwitchHost: The term 'Remove-VDSwitchHost' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

That is Remove-VDSwitchVMHost

[chrischrischris]

Thanks for that (doh!).

The cmdlet ran but failed to remove the VMhost from the vSwitch (vCenter is version 6):

get-vdswitch -Name dvSwitch1 | Remove-VDSwitchVMHost -VMHost sfo-engesx26

Confirm
Are you sure you want to perform this action?
Performing the operation "Removing VMHost(s) 'sfo-engesx26'" on target "dvSwitch1".

[LucD · Accepted solution]

Is there a VMKernel or a Portgroup on that switch that is used by that ESXi node?
You will have to migrate those first.
