• Windows Server 2008 supports user account control (UAC). If you are
logged on with a non-administrator account, use the Administrator:
Command Prompt window when executing any of the following
programs to install or uninstall HDLM:
¢ setup.exe
#
¢ installhdlm (installhdlm utility)
¢ uninstallhdlm (uninstallhdlm utility)
#
This program can also be executed using Run as administrator.
• If you are using Hyper-V in Windows Server 2008, you cannot use HDLM
on a guest OS. Install HDLM on a host OS.
If you want to install or uninstall HDLM on a host OS, first terminate the
Hyper-V manager console. If the Hyper-V manager console is running,
the installation or uninstallation of HDLM will stop. If this happens, you
can continue with the installation or uninstallation of HDLM by first
terminating the Hyper-V manager console.
• If you are using Hyper-V in Windows Server 2008 and an HDLM
management-target device has been allocated as a physical hard disk to a
guest OS, before you perform an HDLM upgrade installation or
uninstallation on a host OS, be sure to unallocate the physical hard disk
from the guest OS. After the upgrade installation or uninstallation has
finished, reallocate the physical hard disk to the guest OS.
• If you are using Hyper-V in Windows Server 2008, you cannot use a
cluster environment on a guest OS.
Notes on Related Software
• 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.
• You cannot use HDLM for Windows and HDLM for VMware on the same
host.
• HDLM uses the following MPIO drivers according to the host OS:
¢
In Windows Server 2003
HDLM uses the MPIO driver on the HDLM DVD that is installed during
HDLM installation. The MPIO driver consists of the following files:
mpio.sys, mpspfltr.sys, mpdev.sys.
¢
In Windows Server 2008
HDLM uses the MPIO driver already installed with the OS, not the
MPIO driver on the HDLM installation DVD.
