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:
