Changing a device not managed by HDLM into one managed by HDLM

To change a device not managed by HDLM into one 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 HDLM to manage is not being managed.

   If the Management status of the relevant HDLM device is represented as unconfigured in the execution result, the device is not being managed by HDLM. Perform this operation if necessary. If it is not necessary to check this, go to step 3.

3. Execute the dlmcfgmgr utility (dlmcfgmgr -i logical_device_file_name_of_HDLM_device ) on the relevant device you want to HDLM to manage.

   The specified device is managed by HDLM.

   The following is an example of executing the dlmcfgmgr utility:

   # /sbin/dlmcfgmgr -i 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 HDLM command to make sure that the relevant device is now managed by HDLM.

   The following is an example of executing the dlmcfgmgr utility:

   # /sbin/dlmcfgmgr -v
