I am trying to disconnect a host from a cluster, remove it and add it back into another vcenter

[Craig_Baltzer]

Have a look at Destroy

https://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/vim.ManagedEntity.html#dest...

I can't test this right now but the privs required to run it on a HostSystem object make it look like its what you're looking for...

[Grzesiekk]

Like Craig said  use the destroy or destroy_task,

if you want to disconnect it before , use DisconnectHost_Task or DisconnectHost .

This will work, already done it few times.

[tdubb123]

I cannot get this to work

get-vmhost vmhost | % {

    $view = get-view $_.id

    $arg = new-object VMware.Vim.HostConnectSpec

    $arg.userName = "root"

    $arg.password = $password

    $arg.force = $true

    $view.DisconnectHost()

    $view.Destroy_task()

}

But in vcenter I got

The operation is not supported on the object. any idea? I put a start-sleep 10 before the Destroy_task() but it would not let me disconnect and remove host

any idea?

[Grzesiekk]

Can you check with 1 host only ?

$vmhost = get-view -viewtype hostsystem -filter @{'name'='YourEsxiName'}

$vmhost.DisconnectHost_Task()

$vmhost.Destroy_Task()

You connect to Virtual center first.

Connect-viserver [name_of_vc] -credential (get-credential)

[tdubb123]

no same error in vcenter. host got disconnected but the remove host task is not working

I was seeing the same issues, although I was using the vSphere Perl SDK instead of the PowerCLI one.  I found this in the Perl API doco for vSphere 6, and I assume PowerCLI mentions the same thing somewhere in its doco for HostSystem.

Invoking destroy on a HostSystem of standalone type throws a NotSupported fault. A standalone HostSystem can be destroyed only by invoking destroy on its parent ComputeResource.

I retrieve the ComputeResource by getting the parent of the HostSystem managed object.  It also is named the same as the host (in the case of a standalone host).  I can't give you the exact PowerCLI code, but I hope this helps!

[LucD]

That is correct, I use the following code to remove a HostSystem

$hostName = 'MyEsx'

$esx = Get-View -ViewType HostSystem -Filter @{'Name'=$hostName}

$parent = Get-View -Id $esx.Parent

$esx.DisconnectHost()

if($parent -is [VMware.Vim.ClusterComputeResource])

{

    $esx.Destroy()

}

elseif($parent -is [VMware.Vim.ComputeResource])

{

    $parent.Destroy()

}
