7.5 The dlmchkpath Utility for Checking HDLM Paths

If you install or uninstall HDLM in a multi-path configuration, the disk might become

corrupted. Use the

dlmchkpath

utility to check HDLM paths and to make sure that

the system is in a single-path configuration. During an upgrade installation, a

re-installation, or uninstallation of HDLM, the

dlmchkpath

utility is executed

automatically. If the system is in a single-path configuration, the

dlmchkpath

utility

displays nothing during an upgrade installation, a re-installation, or uninstallation of

HDLM. A warning dialog box will appear if the system is in a multi-path

configuration.
However, when you use one of the following methods of installing HDLM and the

system is determined to be a multi-path configuration, the installation will terminate

without displaying any warning dialog boxes:

Upgrade installation using the unattended installation
Re-installation using the unattended installation

When the

dlmchkpath

utility is executed manually, a message will appear as shown

in the execution example in 7.5.2 Parameters. This utility is located in the following

location:
