 If HDLM is installed on a host in which the MPIO driver has already been installed, the
MPIO driver that is bundled with the HDLM CD-ROM overwrites the existing MPIO driver.
The MPIO driver consists of the mpio.sys, mpspfltr.sys, and mpdev.sys files.
 Do not install any multi-path management software other than HDLM. If multi-path
management software other than HDLM has been installed on the host, uninstall the
software, and then restart the host before re-installing HDLM.
 If you perform an upgrade installation or re-installation of HDLM, a message might
appear, asking you to confirm whether you want to overwrite the MPIO driver. If this
message appears, stop the installation, make sure that no other multi-path management
software is installed, and then retry the installation.

change the settings for Oracle RAC 10g after building the environment.
– Release of 10.1.0.3.0 or later of Oracle RAC 10g is being used.
