3.9.3.2 Uninstallation Procedure for an MSCS or VCS Environment
To uninstall HDLM in an MSCS or VCS environment:
1. Log on to Windows as a member of the administrators group.
2. Stop all the processes and services that use the HDLM management-target paths
including any process or service of an application, such as a DBMS, that is using the
HDLM management-target path.
3. Stop MSCS or VCS in all the hosts that make up the cluster. When MSCS is used, follow
this procedure:
In Control Panel, choose Administrative Tools and then Services. In the list of services,
right-click Cluster Service. Then, from the Action menu choose Stop to stop the
service. The message prompting you to restart the system is displayed. In this case,
choose No.
4. If a host and a storage system connect via multiple paths, reconfigure it so that one path
connects one host to the storage system (single-path configuration).
Uninstalling HDLM in a multi-path configuration, which uses more than one path to
connect the host to the storage system, may cause disk contents to be incorrect when
the host restarts. Make sure that you uninstall HDLM in the single path configuration.
Figure 3.7 shows a single path configuration and a multi-path configuration.
