Therefore, make a note of the original values of
MISSCOUNT
and
DISKTIMEOUT
before changing them.
„ If you install HDLM while resident software (such as antivirus software) is
running, HDLM might not operate correctly. Before installing HDLM, make sure
that you have stopped all software programs, including all resident software.
3.4.6 Notes on New Installations and Upgrade Installations
„ When installing HDLM, use only one cable to connect the host to the storage
system until instructed otherwise in the procedure in section 3.5.3 Performing a
New Installation of HDLM on Windows Server 2003, or 3.5.4 Performing a New
Installation of HDLM on Windows Server 2008. If the host is restarted while it is
connected to the storage system via multiple paths at a time other than those
indicated in the procedure in section 3.5.3 Performing a New Installation of
HDLM on Windows Server 2003, or 3.5.4 Performing a New Installation of
HDLM on Windows Server 2008, the contents of the disk might become
corrupted.Note that you can upgrade or re-install HDLM in a multipath
configuration in Windows Server 2003 SP1 or later and in Windows Server 2008.
„ HDLM does not support multiple-path configurations in which both an FC-SAN
and IP-SAN exist on the same LU.
„ If you install HDLM for the first time, or perform an upgrade installation of
HDLM after the license has expired, a license key is necessary. To update the
HDLM license, execute the
dlnkmgr
command's
set -lic
operation. The
expiration date of the license key is determined by the license key specified in the
license key file or the input license key type. For information on license key types
and the
set
operation, see 6.6 set (Sets Up the Operating Environment).
„ Installing HDLM requires 70 MB of unused capacity on the system drive.
„ Terminate all programs that are running before installing HDLM.
„ If you select a folder for the HDLM installation folder, and then suddenly decide
to change the folder for the installation folder, the first folder that you selected
might be created along with the actual folder you want to use for the installation
folder. Delete the created folder because a folder other than the last selected folder
is not necessary.
„ Depending on the environment, installing HDLM might take a while to finish. Do
not terminate the installation process while a progress bar for installation is
displayed. The following is an approximate calculation of the time required for
installation:
(5 x number-of-connected paths) seconds
„ If installation of HDLM terminates abnormally and the KAPL09016-E message
is output, check whether an HDLM version from another OS has been installed
