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 will occur 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 make up the cluster. If different
versions of HDLM are installed, the cluster system might not operate
correctly. If the HDLM Version and Service Pack Version, which are
displayed by executing the following command, are the same, then the
versions of HDLM will also be the same:
dlnkmgr view -sys -sfunc
Notes on Windows
•
We recommend that you install Windows and HDLM on an internal host
disk. If you install them on an HDLM management-target disk, the
following problems might occur:
¢
You might not be able to store the OS crash-dump and error
information on the disk.
¢
After removing HDLM, some files might not be deleted correctly.
•
When restoring a Windows system disk from a backup, restore the disk to
a single-path configuration.
After restoring the disk, confirm that HDLM is running properly, and then
change to a multi-path configuration.
•
If the size of the Path system environment variable is 1024 bytes or
more, the HDLM manager might not be able to start. When the 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 the HDLM manager fails to start, delete all unnecessary character
strings in the path so that the size of the Path system environment
variable is 1024 bytes or less:
