Hitachi Dynamic Link Manager Software Users Guide for Windows (7.6)

For details on how to change MISSCOUNT and DISKTIMEOUT, contact the
company with which you have an Oracle Support Services contract.
Note that when you remove HDLM from the above configuration, you
must reset the values of MISSCOUNT and DISKTIMEOUT to their original
values. Therefore, make a note of the original values of MISSCOUNT and
DISKTIMEOUT before changing them.
• Configurations in which Oracle RAC is installed in Oracle Cluster File
System are not supported.
• 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.
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
Performing a New Installation of HDLM on Windows Server 2003 on page
3-29, or Performing a New Installation of HDLM on Windows Server 2008
and Windows Server 2012 on page 3-52. 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
Performing a New Installation
of HDLM on Windows Server 2003 on page 3-29, or Performing a New
Installation of HDLM on Windows Server 2008 and Windows Server 2012
on page 3-52, 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 , in Windows Server 2008 and in
Windows Server 2012.
• 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
set (Sets Up
the Operating Environment) on page 6-16 .
• 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:
