To change a device managed by HDLM into one not managed by HDLM:

The following operation can be done without restarting the host.

  1. Stop all accesses to the relevant LU.

  2. Execute the HDLM-configuration definition utility (dlmcfgmgr -v) to check if the device you want to exclude from HDLM management is being managed by HDLM.

    The following is an example of executing the dlmcfgmgr utility:

    # /sbin/dlmcfgmgr -v

    If the Management status of the relevant HDLM device is represented as configured in the execution result, this means that the device is managed by HDLM.

  3. Execute the dlmcfgmgr utility (dlmcfgmgr -ological_device_file_name_of_HDLM_device ) on the relevant device you want to exclude from HDLM management.

    The specified device is excluded from HDLM management.

    The following is an example of executing the dlmcfgmgr utility:

    # /sbin/dlmcfgmgr -o name-of-logical-device-file-for-HDLM-device
  4. Refer to /var/opt/DynamicLinkManager/log/dlmcfgmgr1.log or execute the dlmcfgmgr utility (dlmcfgmgr -v) or the view operation (dlnkmgr view -path) of the dlnkmgr command to make sure that the relevant device is no longer managed by HDLM.

    The following is an example of executing the dlmcfgmgr utility:

    # /sbin/dlmcfgmgr -v
