Removing the Entry for an Omnissa Horizon Connection Server Instance Using the ‑S Option

You can use the vdmadmin command with the -S option to remove the entry for a Horizon Connection Server instance from the Omnissa Horizon configuration.

Syntax

vdmadmin -S [-b authentication_arguments] -r -s server

Usage Notes

To ensure high availability, Omnissa Horizon allows you to configure one or more replica Horizon Connection Server instances in a Horizon Connection Server group. If you disable a Horizon Connection Server instance in a group, the entry for the server persists within the Omnissa Horizon configuration.

To make the removal permanent, perform these tasks:

1. Uninstall the Horizon Connection Server instance from the Windows Server computer by running the Horizon Connection Server installer.
2. Remove the Adam Instance VDMDS program from the Windows Server computer by running the Add or Remove Programs tool.
3. If the Horizon Connection Server is part of a CPA federation then, remove the Adam Instance VDMDSG program from the Windows Server computer by running the Add or Remove Programs tool.
4. On another Horizon Connection Server instance, use the vdmadmin command to remove the entry for the uninstalled Horizon Connection Server instance from the configuration.

If you want to reinstall Omnissa Horizon on the removed systems without replicating the Omnissa Horizon configuration of the original group, restart all the Horizon Connection Server hosts in the original group before performing the reinstallation. This prevents the reinstalled Horizon Connection Server instances from receiving configuration updates from their original group.

Note: If you remove the Horizon Connection Server instance with the vdmadmin -S command without a clean uninstallation of LDAP instances on the server as described above, then you might accidentally remove the schema master node, which blocks future upgrades and installations of Horizon Connection Servers.

Options

The -s option specifies the NetBIOS name of the Horizon Connection Server instance to be removed.

Examples

Remove the entry for the Horizon Connection Server instance connsvr3.

vdmadmin -S -r -s connsvr3
