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:
HDLM-installation-folder
