When you use HDLM in a cluster configuration, you must install the same version of HDLM on all the nodes that comprise the cluster. If different versions of HDLM are installed, the cluster system may not operate correctly. If the HDLM Version and Service Pack Version, which are displayed by executing the following command, are the same, the versions of HDLM are the same:
# /opt/DynamicLinkManager/bin/dlnkmgr view -sys
