The dlmchkpath Utility for Checking HDLM Paths
If you install or remove 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 removal 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 removal 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
Parameters on page 7-14. This utility is
located in the following location:
HDLM-installation-folder\bin
Format
dlmchkpath {-singleconnect | -h}
Parameters
