\"removingorphanedstalevdi01\"<\/p>\n

Horizon sometimes fails to\u00a0process\u00a0some VMs\u00a0leaving orphaned or stale virtual desktops in pools that cannot be removed from the GUI.<\/p>\n

Manually\u00a0removing orphaned or stale virtual desktops\u00a0from the vCenter<\/strong> is not enough to\u00a0clean the\u00a0VMware View Manager and its database.<\/p>\n

 <\/p>\n

Remove the VDI<\/h2>\n

From the Horizon View Administrator<\/strong>, right click the machine to delete\u00a0and click Remove<\/strong>.<\/p>\n

\"removingorphanedstalevdi02\"<\/p>\n

Click OK<\/strong> to proceed.<\/p>\n

\"removingorphanedstalevdi03\"<\/p>\n

This is one type of error you can experience. in the example the vCenter Server is corrupted<\/strong>\u00a0and the machine cannot be removed.<\/p>\n

\"removingorphanedstalevdi04\"<\/p>\n

 <\/p>\n

Clean ADAM database<\/h2>\n

To remove the orphaned VM, the View database must be cleaned in order to remove all the entries no longer needed. From the Horizon Connection Server<\/strong>, open the ADSI Edit<\/strong>.<\/p>\n

\"removingorphanedstalevdi05\"<\/p>\n

Right click the ADSI Edit<\/strong> item and select Connect to...<\/strong><\/p>\n

\"removingorphanedstalevdi06\"<\/p>\n

In the Connection Settings<\/strong> window, enter\u00a0the following parameters:<\/p>\n

Name<\/strong>: View ADAM Database
\nConnection Point<\/strong>: dc=vdi,dc=vmware,dc=int
\nComputer<\/strong>:\u00a0localhost:389<\/p><\/blockquote>\n

Click OK<\/strong> to confirm.<\/p>\n

\"removingorphanedstalevdi07\"<\/p>\n

If the connection to the ADAM database fails<\/strong>, one reason could be that the\u00a0user logged in the Connection Server doesn't have the correct permissions<\/strong> to administer VMware View.<\/p>\n

\"removingorphanedstalevdi08\"<\/p>\n

In the View Administrators group<\/strong> enter the account to entitle then\u00a0click OK<\/strong>.<\/p>\n

\"removingorphanedstalevdi09\"<\/p>\n

The connection to the ADAM database is now successful.<\/p>\n

\"removingorphanedstalevdi10\"<\/p>\n

Right click the View ADAM Database<\/strong> and select New > Query...<\/strong><\/p>\n

\"removingorphanedstalevdi11\"<\/p>\n

Give the\u00a0query a Name<\/strong>\u00a0(i.e. VDI) and click Browse<\/strong>. Select Servers<\/strong> and click OK<\/strong>.<\/p>\n

\"removingorphanedstalevdi12\"<\/p>\n

Enter the string below in the\u00a0Query String<\/strong>\u00a0field specifying the orphaned VM name.\u00a0Click OK<\/strong>\u00a0to execute the query.<\/p>\n

(&(objectClass=pae-VM)(pae-displayname=VM_to_remove<\/em>))
\ni.e. (&(objectClass=pae-VM)(pae-displayname=view-lab-1<\/em><\/span>))<\/p><\/blockquote>\n

\"removingorphanedstalevdi13\"<\/p>\n

As result, a new ADSI Edit\u00a0item<\/strong> appears at the bottom of the window (VDI<\/strong>). Take note of the CN string<\/strong> in the right pane.<\/p>\n

i.e.\u00a0CN=ccbace2f-e506-48c4-8248-d92d5821876a<\/p><\/blockquote>\n

\"removingorphanedstalevdi14\"<\/p>\n

Double click the CN object<\/strong> and check if the\u00a0pae-DisplayName<\/strong>\u00a0reflects the name assigned to the VDI. Click OK<\/strong>.<\/p>\n

\"removingorphanedstalevdi15\"<\/p>\n

In the Servers OU<\/strong>,\u00a0locate the entry with the same CN<\/strong>.<\/p>\n

\"removingorphanedstalevdi16\"<\/p>\n

Again, double click the CN object<\/strong> and check if the\u00a0pae-DisplayName<\/strong>\u00a0reflects the name assigned to the VDI then click OK<\/strong>.<\/p>\n

\"removingorphanedstalevdi17\"<\/p>\n

Right click the verified CN object and select Delete<\/strong>.<\/p>\n

\"removingorphanedstalevdi18\"<\/p>\n

 <\/p>\n

Click Yes<\/strong> to confirm.<\/p>\n

\"removingorphanedstalevdi19\"<\/p>\n

The object has been removed from the ADAM Database.<\/p>\n

\"removingorphanedstalevdi20\"<\/p>\n

When you refresh<\/strong> the Horizon View Administrator screen, the orphaned virtual desktop has been removed.<\/p>\n

\"removingorphanedstalevdi21\"<\/p>\n

 <\/p>\n

Clean Active Directory<\/h2>\n

Remove the computer also from the Active Directory<\/strong>.<\/p>\n

\"removingorphanedstalevdi22\"<\/p>\n

Click Yes<\/strong> to confirm.<\/p>\n

\"removingorphanedstalevdi23\"<\/p>\n

In this procedure the old vCenter Server was corrupted\u00a0and the Horizon View database<\/strong> installed in the same VM was\u00a0not available as well. To complete the overall procedure<\/strong>, the orphaned VM should be removed also from the vCenter Server and the Horizon View database.<\/p>\n
