 Before installing or upgrading HDLM 5.5 or later, make sure that no other application is
using an HDLM management-target LU.
 When HDLM 5.5 or later is installed for the first time, the event described below occurs
and is output to the event log. However, it does not affect the system or HDLM
operations.
Description
Event provider attempted to register query "select * from WMIEvent" whose target class
"WMIEvent" does not exist. The query will be ignored.
 When you use HDLM in a cluster configuration, you must install the same version of
HDLM on all the nodes that comprise the cluster. If different versions of HDLM are
installed, the cluster system may not operate correctly. If the HDLM Version and
Service Pack Version, which are displayed by executing the following command,
are the same, the versions of HDLM are the same:
>dlnkmgr view -sys -sfunc
3.4.4 Notes on Windows
 Before upgrading the OS from Windows 2000 Server to Windows Server 2003 or re-
installing the OS during system recovery, always uninstall HDLM. After upgrading the OS,
install the appropriate HDLM version for the upgraded operating system.
 We recommend you install the operating system and HDLM on an internal disk of the
host. If you install them on an HDLM management-target disk, the following problems
might occur.
– You might not be able to store the operating system crash-dump and error
information on the disk.
– After uninstalling HDLM, files might not be deleted.
 If the size of the Path system environment variable is 1024 bytes or more, HDLM
Manager might not be able to start. When HDLM Manager fails to start, the following
message is output to the Windows event log (system):
Source: Service Control Manager
Type: Error
Event ID: 7000
Description: DLMManager service could not be started for the following reason: The
service did not respond to the start request or control request within the specified
period.
If HDLM Manager fails to start, delete unnecessary character strings in the path so that
the size of the Path system environment variable is 1024 bytes or less:
