HP XP7 Storage - Manual (Page 89)

• 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:
Windows-installation-folder\inf. In addition, two other oemn.pnf files will
also be created in this folder.
If either the KAPL09257-W or the KAPL09258-E message appears,
perform the following procedure to delete the two oemn.inf files and two
oemn.pnf files:
a
.
Check the MPIO driver version indicated in the KAPL09257-W or the
KAPL09258-E message.
In this example, the MPIO driver version is n.nn.nnnn.nnnn (n
represents numbers):
KAPL09257-W HDLM cannot be installed on a system where MPIO
n.nn.nnnn.nnnn has already been installed.
b
.
Find the setup information files (which have the file extension inf)
that contain the version number information, by using the Windows
search function in the following folder:
Windows-installation-folder\inf
There will be two oemn.inf files.
c
.
Make sure that the contents of the oemn.inf files you have found are
identical to the files mpio.inf and mpdev.inf for the MPIO driver that
is installed on the host.
If you have removed HDLM and then install an earlier version of
HDLM, check the mpio.inf and mpdev.inf files on the DVD for the
later version of HDLM.
