3.9.3 Uninstalling HDLM

After HDLM is uninstalled, sometimes the files below remain undeleted. The files will be deleted when you restart the host according to the procedure.

HDLM-installation-folder\DLMTools\perfhdlm\provhdlm.dll
HDLM-installation-folder\lib\libdlm.dll
HDLM-installation-folder\lib\hdlmhcc60.dll

The default installation folder for HDLM is C:\Program Files\HITACHI\DynamicLinkManager.

The following describes how to uninstall HDLM.

Organization of this subsection
(1) Uninstallation Procedures - in a Non-Cluster Environment
(2) Uninstallation Procedures - MSCS or VCS Environment
(3) Uninstallation Procedures - Oracle RAC Environment

(1) Uninstallation Procedures - in a Non-Cluster Environment

To uninstall HDLM:

  1. Log on to Windows as a member of the Administrators group.

  2. Stop all the processes and services that use the HDLM management-target paths.
    Stop any process or service of an application, such as a DBMS, that is using the HDLM management-target path.

  3. If the host and the storage subsystem connect via multiple paths, reconfigure it so that only one path connects the host to the storage subsystem (single-path configuration).
    After uninstalling HDLM, if you start the host in a multi-path configuration, which uses more than one path to connect the host to the storage subsystem, the disk contents may become incorrect.
    Figure 3-6 Single path configuration and multi-path configuration shows a single path configuration and a multi-path configuration.

  4. Start the uninstallation program.
    In Control Panel, choose Add/Remove Programs, and then Change or Remove Programs. From the list of programs, select Dynamic Link Manager, and click the Change/Remove button.

  5. The dlmchkpath utility is automatically executed. If a warning dialog box appears, follow the procedure below:
    • Cancel the uninstallation. Reconfigure the system into a single-path configuration, and then perform the uninstallation again. For details about the dlmchkpath utility, see 8.5 dlmchkpath (utility for checking HDLM paths).
    • If a warning dialog box is not displayed, go to the next step.

  6. Follow the instructions shown in the messages that appear on the window.
    If the KAPL09005-E message appears, stop the HDLM manager according to the procedure in 4.5.2 Stopping the HDLM manager. After stopping the HDLM manager, restart the uninstallation program.

  7. When uninstallation finishes, shutdown the host.

  8. Start the host.

  9. When uninstallation finishes, a dialog box appears prompting you to restart the host.
    Click the OK button to restart the host.

(2) Uninstallation Procedures - MSCS or VCS Environment

To uninstall HDLM:

  1. Log on to Windows as a member of the Administrators group.

  2. Stop all the processes and services that use the HDLM management-target paths.
    Stop any process or service of an application, such as a DBMS, that is using the HDLM management-target path.

  3. Stop MSCS or VCS in all the hosts that make up the cluster.
    When MSCS is used, follow the procedure described below.
    In Control Panel, choose Administrative Tools and then Services. In the list of services, right-click Cluster Service. Then, from the Action menu choose Stop to stop the service.
    The message prompting you to restart the system is displayed. In this case, choose No.

  4. If a host and a storage subsystem connect via multiple paths, reconfigure it so that one path connects one host to the storage subsystem (single-path configuration).
    Uninstalling HDLM in a multi-path configuration, which uses more than one path to connect the host to the storage subsystem, may cause disk contents to be incorrect when the host restarts. Make sure that you uninstall HDLM in the single path configuration.
    Figure 3-7 Single path configuration and multi-path configuration shows a single path configuration and a multi-path configuration.

  5. Start the uninstallation program.
    In Control Panel, choose Add/Remove Programs, and then Change or Remove Programs. From the list of programs, select Dynamic Link Manager, and click the Change/Remove button.

  6. The dlmchkpath utility is automatically executed. If a warning dialog box appears, follow the procedure below:
    • Cancel the uninstallation. Reconfigure the system into a single-path configuration, and then perform the uninstallation again. For details about the dlmchkpath utility, see 8.5 dlmchkpath (utility for checking HDLM paths).
    • If a warning dialog box is not displayed, go to the next step.

  7. Follow the instructions shown in the messages that appear on the window.
    Uninstall HDLM from all the hosts that make up the cluster.
    If the KAPL09005-E message appears, stop the HDLM manager according to the procedure in 4.5.2 Stopping the HDLM manager. After stopping the HDLM manager, restart the uninstallation program.

  8. When uninstallation finishes, shut down all the hosts that make up the cluster.

  9. Confirm that all hosts are turned off, and are in a single-path configuration.

  10. Start each of the hosts that make up the cluster.

(3) Uninstallation Procedures - Oracle RAC Environment

To uninstall HDLM:

  1. Log on to Windows as a member of the Administrators group.

  2. Stop the Oracle RAC instance of the host where HDLM is to be uninstalled.

  3. If a host and a storage subsystem connect via multiple paths, reconfigure it so that one path connects one host to the storage subsystem (single-path configuration).
    Uninstalling HDLM in a multi-path configuration, which uses more than one path to connect the host to the storage subsystem, may cause disk contents to be incorrect when the host restarts. Make sure that you uninstall HDLM in the single path configuration.
    Figure 3-7 Single path configuration and multi-path configuration shows a single path configuration and a multi-path configuration.

  4. Start the uninstallation program.
    In Control Panel, choose Add/Remove Programs, and then Change or Remove Programs. From the list of programs, select Dynamic Link Manager, and click the Change/Remove button.

  5. The dlmchkpath utility is automatically executed. If a warning dialog box appears, follow the procedure below:
    • Cancel the uninstallation. Reconfigure the system into a single-path configuration, and then perform the uninstallation again. For details about the dlmchkpath utility, see 8.5 dlmchkpath (utility for checking HDLM paths).
    • If a warning dialog box is not displayed, go to the next step.

  6. Follow the instructions shown in the messages that appear on the window.
    If the KAPL09005-E message appears, stop the HDLM manager according to the procedure in 4.5.2 Stopping the HDLM manager. After stopping the HDLM manager, restart the uninstallation program.

  7. After uninstallation finishes, restart the host.

  8. Start the Oracle RAC instance of the host.

  9. On all the hosts comprising the cluster system, perform steps 1 through 8.

  10. When using release 10.1.0.3.0 or later of Oracle RAC 10g, the value set in the MISSCOUNT parameter, for which the threshold of the I/O timeout of the voting disk is set, must be returned to the value that was set before HDLM was installed. For details on how to set the value of the MISSCOUNT parameter, contact the company with which you have a support service contract for Oracle.
