3. If a host and a storage system connect via multiple paths, reconfigure it so that one path
connects one host to the storage system (single-path configuration). Uninstalling HDLM
in a multi-path configuration, which uses more than one path to connect the host to the
storage system, 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 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 this procedure:
– Cancel the uninstallation. Reconfigure the system into a single-path configuration,
and then perform the uninstallation again. For details about the dlmchkpath
utility, see section
8.5.
– 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
section
4.5.2. 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.
