Uninstall the Software from a Cluster

Click on a link below to go to a specific section of the software uninstall:

Before You Begin
  • When uninstalling the CommNet Server, close any open user connections to the CommNet Server database (through either SQL Analyzer, SQL Server Management Studio, isql, osql, etc.) If there are any open connections the uninstaller may not be able to delete the CommNet Server database.
  • Verify that no jobs are in progress or scheduled to occur while the software is being uninstalled. If jobs are scheduled, either perform the uninstall at another time or disable the jobs.
  • Verify that the CommNet Browser is closed.
  • Verify that the active and passive nodes are available. If the passive node is available during the uninstall of the active node, the software will automatically uninstall the passive node.
  • Verify that the cluster is set to its original state (i.e., the active and passive nodes are in the same state of ownership for their disk groups as they were during installation).
  • Uninstall the CommNet Server from the computer where it was installed. This will prevent any registration errors that may occur if uninstalled remotely.

Uninstall Procedure

Getting Started
1. Log on to the computer as the local Administrator or as a member of the local Administrators group on that computer. For clustered computers, log on as Domain User with administrative privileges to all nodes in the cluster.
