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
The following table shows the related programs used when creating a cluster:

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.
- #4
Configurations that include the Automatic Storage Management (ASM) function (using HDLM devices) and Oracle Grid Infrastructure are supported.
Notes to be observed when directly specifying HDLM device names for Oracle ASM disks are provided.
For details, see the notes on specifying HDLM device files (block devices) for the Oracle ASM disks in an environment combining Oracle RAC 19c with HDLM in SETTINGS_FOR_ORACLE=GUID-D8DEC032-F8B3-4EDF-91F6-8B13FE76131C=4=EN=.html.
- #5
Configurations that include the Automatic Storage Management (ASM) function using ASM Filter Driver (ASMFD) and Oracle Grid Infrastructure are supported.
When specifying HDLM device files (block devices) via the ASM Filter Driver (ASMFD), run the command to enable HDLM devices.
For details, see the notes in SETTINGS_FOR_ORACLE=GUID-D8DEC032-F8B3-4EDF-91F6-8B13FE76131C=4=EN=.html.
