• 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 remove HDLM on a host OS, first terminate the
Hyper-V manager console. If the Hyper-V manager console is running,
the installation or removal of HDLM will stop. If this happens, you can
continue with the installation or removal of HDLM by first terminating the
Hyper-V manager console.
• If you are using Hyper-V in Windows Server 2008, you cannot use a
cluster environment on a guest OS.
• If you are using Hyper-V, unallocate the physical hard disk of an HDLM
management-target device that you have allocated to a guest OS before
you perform an installation, upgrade installation, or removal of HDLM on a
host OS. Then, after the installation, upgrade installation or removal of
HDLM on the host OS, allocate the physical hard disk to the guest OS
again.
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, remove 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 , or Windows Server 2012
HDLM uses the MPIO driver already installed with the OS, not the
MPIO driver on the HDLM installation DVD.
• If you attempt to install HDLM on a Windows Server 2003 host on which
an MPIO driver has already been installed, and the MPIO driver version
differs from that of the driver bundled with HDLM, the KAPL09127-W
message is output. This message asks whether it is OK to overwrite the
existing MPIO driver. If you are upgrading HDLM, continue the
installation. If any multi-path management software other than HDLM
exists on the host, cancel the installation, and then remove the software.
• If you install HDLM, the KAPL09257-W or KAPL09258-E message might
appear. If either of the messages appears, the version of the MPIO driver
on the host is later than the one bundled with HDLM. Also, if you install a
piece of multi-path management software other than HDLM, the MPIO
driver might be installed. In this case, delete the setup information files
for the installed MPIO driver, and then reinstall HDLM. The MPIO driver
setup information is defined in the files mpio.inf and mpdev.inf. When
an MPIO driver is installed, these files are renamed to oemn.inf (where n
represents a number), and then registered in the following folder:
