If the key is displayed, perform the steps beginning with step 5. Even
when you release the setup for Quorum devices and disk device groups,

If the key is not displayed, perform the steps beginning with step 9.

Make sure that the logical device files for the sd or ssd device are backed
up.
When you restart the node, with the reconfiguration option specified,
after running the dlmsetconf utility in the next step (step 10), the logical
device files of the sd or ssd device to be managed by HDLM will be
deleted. Make sure that these files are backed up before you execute the
dlmsetconf utility to restart the node. For details on how to back up files,
see step 4 in Performing Operations on Devices to Be Managed by HDLM
