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

It is recommended that you use external redundancy for ASM disk groups. To use normal or high redundancy in an environment in which a multipath configuration is used between servers and storage systems, contact the Oracle Corporation about the necessary Oracle settings.
- #2
Only configurations that include the Automatic Storage Management (ASM) function (using raw devices) and Oracle SEHA are supported.
