VxVM and VIOM rely on the VIOM vxdclid plugin to interact correctly. This plugin is based on the VxVM version and so the introduction of a new VxVM version may cause the vxdclid process to coredump. A new plugin may need to be put in place to prevent further coredumps.
If vxdclid coredumps are encountered on a VIOM MH following the installation of a VxVM patch, the following steps would be recommended:
1. Capture the vxgetcore output from two of the vxdclid coredumps
/opt/VRTSspt/vxgetcore/vxgetcore -c
2. To prevent vxdclid coredumps from being generated, stop the vxdclid process by running the following command:
/opt/VRTSsfmh/adm/dcliunsetup.sh
Confirm that the vxdclid process is not running in the 'ps -ef' output
3. Contact Veritas Support and provide them with the vxgetcore outputs captured in Step 1. The vxdclid coredumps can then be examined by Veritas Support and (if needed) a new plugin provided.
