3.4.3 Notes on HDLM versions

• If HDLM 5.4 or earlier has been installed, uninstall HDLM first and then proceed with the new HDLM installation in accordance with the procedure described in 3.5.5 Migrating from HDLM 5.4 or earlier to HDLM 5.5 or later.
• In HDLM 5.6 or later, trace files for HDLM versions earlier than 5.6 are divided into integrated trace files and trace files. The logs for the HDLM command and HDLM GUI operations are output to integrated trace files. Trace information for an HDLM manager is output to trace files. The output destinations for the files change as follows:
  
  • When you migrate from an HDLM version earlier than 04-00 to an HDLM version 5.6 or later
    - Trace files before migration: drive-for-program-installation:\Program Files^#\HITACHI\HNTRLib\spool\hntrn.log (n indicates a file number)
    - Integrated trace files after migration: drive-for-program-installation:\Program Files^#\HITACHI\HNTRLib2\spool\hntr2n.log (n indicates a file number)
    - Trace files after migration: drive-for-program-installation:\Program Files\HITACHI\DynamicLinkManager\log\hdlmtrn.log (n indicates a file number)
    The underlined part indicates the folder specified during installation.
    
  • When you migrate from HDLM version 04-01 - 5.5 to HDLM version 5.6 or later, or when you perform an upgrade installation from HDLM 5.5 or later
    - Trace files before migration or upgrade: drive-for-program-installation:\Program Files^#\HITACHI\HNTRLib\spool\hntrn.log (n indicates a file number)
    - Integrated trace files after migration or upgrade: drive-for-program-installation:\Program Files^#\HITACHI\HNTRLib2\spool\hntr2n.log (n indicates a file number)
    #
    In Windows Server 2003(IPF and x64), replace this part with Program Files (x86).
    - Trace files after migration or upgrade: drive-for-program-installation:\Program Files\HITACHI\DynamicLinkManager\log\hdlmtrn.log (n indicates a file number)
    The underlined part indicates the folder specified during installation.
    
• 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:
