HiCommand Dynamic Link Manager (HDLM) for Windows Systems User's Guide (HIT5201-96001, January 2008)

116 Chapter 3 Creating an HDLM Environment
The default installation folder for HDLM is C:\Program
Files\HITACHI\DynamicLinkManager.
The following subsections describe how to uninstall HDLM in different environments.
3.9.3.1 Uninstallation Procedure for a Non-Cluster Environment
To uninstall HDLM in a non-cluster 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. This
includes any process or service of an application, such as a DBMS, that is using the HDLM
management-target path.
3. If the host and the storage system connect via multiple paths, reconfigure it so that only
one path connects the host to the storage system (single-path configuration).
After uninstalling HDLM, if you start the host in a multi-path configuration, which uses
more than one path to connect the host to the storage system, the disk contents may
become incorrect.
Figure 3.6 shows a single path configuration and a multi-path configuration.

4. Start the uninstallation program. In Control Panel, choose Add/Remove Programs, and
then Change or Remove Programs. From the list of programs, select Dynamic Link
Manager, and click the Change/Remove button.
5. The dlmchkpath utility is automatically executed. If a warning dialog box appears,
follow the procedure below:
– Cancel the uninstallation. Reconfigure the system into a single-path configuration,
and then perform the uninstallation again. For details about the dlmchkpath
utility, see section
8.5.
– If a warning dialog box is not displayed, go to the next step.
