HiCommand Dynamic Link Manager User's Guide (for Windows(R))

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 OS.
• We recommend you install the OS 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 OS 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:
  

  For Windows Server 2003 (IPF) and Windows Server 2003 (x64):

  Windows-installation-drive:\Program Files (x86)\Common Files\Hitachi

  HDLM-installation-folder\bin

  HDLM-installation-folder\lib

  For Windows versions other than the above:

  Windows-installation-drive:\Program Files\Common Files\Hitachi

  HDLM-installation-folder\bin

  HDLM-installation-folder\lib

  For Windows Server 2003 SP1 and Windows Server 2003 R2 (no service pack), if you do not want to use one of the above methods, you can use a Microsoft hotfix to start HDLM Manager. For details about how to obtain and use the hotfix and how it affects the system, contact Microsoft.
  
• Before installing HDLM, enable the setting for automatically shortening file and folder names (8.3 format). If this setting is disabled, shortened names might not be generated in the Intel 32 folder in which the HDLM uninstallation program is stored, and uninstallation of HDLM cannot be performed because the uninstallation program cannot be started. If shortened names are not generated in the Intel 32 folder, uninstall HDLM according to the procedure described in 3.9.2 Notes on uninstalling HDLM.
• HDLM uses the Windows Installer service during installation. Therefore, when you install HDLM, take the following measures:

1. In the Startup Type setting for the Windows Installer service, specify Manual or Automatic.
2. Before installing HDLM, make sure that other programs are not using the Windows Installer service.

If you install HDLM while the Startup Type setting for the Windows Installer service is disabled or while another program is using HDLM, the following message appears and installation might fail:

 
KAPL09034-E  An Internal error occurred in the HDLM Installer. Code = -99 nnnnn
 

If this message appears during a new installation of HDLM:

Confirm that conditions 1 and 2 above are met, and install HDLM again.

If this message appears during an upgrade or re-installation of HDLM:

Confirm that conditions 1 and 2 above are met, and then reperform an upgrade or re-installation of HDLM.

You must be careful because even though an upgrade or re-installation of HDLM has actually failed, the Add/Remove Programs window might indicate that HDLM has been installed normally.

• If you install HDLM when either of the following conditions exists, an error might be displayed for the mirror disk in the Disk Management window of Windows.
  
  • A mirror disk volume that uses a Windows dynamic disk exists among the HDLM management-target devices
  • An application that uses the dmaadmin service is being executed.
  This error does not affect the data of the HDLM management-target devices. If you restart the host and then activate the disk in the Disk Management window of Windows, this error will not appear. To prevent the error from occurring, perform the following before installing HDLM:
  
  • When a mirror disk volume that uses a dynamic disk exists among the HDLM management-target devices
    Close the management console for the disk.
    
  • When the application that uses the dmaadmin service is being executed
    Stop the application that uses the dmaadmin service.
    
• In Windows Server 2003 (x64), do not create the data stored in the GUID Partition Table (GPT).
• When installing HDLM, The name of the HDLM installation folder and the names of all its parent folders must fulfill all of the following conditions:
  
  • The name must not be a reserved name specified in the OS.
    Reserved names specified in the OS include, for example, CON, AUX, COM1 to COM9, LPT1 to LPT9, PRN, and NUL.
    
  • The name must contain the following characters only:
    A - Z, a - z, 0 - 9, -, _, ., @, or a single byte space
    
  • The end of the name cannot be a single byte space.
  • The name cannot contain two or more single byte spaces consecutively.
  If you attempt to install the HDLM in a folder that does not fulfill these conditions, problems such as those described in Table 3-9 Problems and actions to take when specifying a folder that does not fulfill the conditions for an HDLM installation might occur. In such a case, reinstall the HDLM according to the procedures given below.
  

  Table 3-9 Problems and actions to take when specifying a folder that does not fulfill the conditions for an HDLM installation

  Problem	Action
  An internal error occurred and the installation was interrupted.	Specify a folder that fulfills the above conditions and reinstall the HDLM.
  After the installation finished, error information could not be collected when you executed the DLMgetras utility for collecting HDLM error information.	Uninstall the HDLM and then install it again specifying a folder that fulfills the above conditions.
