The vxdclid plugin did not interact properly with the above versions of VxVM and VRTSsfmh.

The 7.4.1.3408 vxdclid plugin can be used to avoid these vxdclid coredumps and can be installed using the following steps:

1. Stop the vxdclid process:
# /opt/VRTSsfmh/etc/vxdcli.sh stop

2. Confirm that the vxdclid process is not running in the ps -ef output

3. Take the backup of the old libvxlistsf_s.so file
# cp /opt/VRTSsfmh/plugins/vxlist/server/741/libvxlistsf_s.so /opt/VRTSsfmh/plugins/vxlist/server/741/libvxlistsf_s.so_orig

4. Copy the new libvxlistsf_s.so file to the MH and replace the original plugin. For example, if the plugin had been copied to /var/tmp:
# cp /var/tmp/libvxlistsf_s.so /opt/VRTSsfmh/plugins/vxlist/server/741/

5. Start the vxdclid process:
# /opt/VRTSsfmh/etc/vxdcli.sh start

6. Confirm that the vxdclid process is seen in the ps -ef output.

7. Run the /opt/VRTSsfmh/bin/vxlist command and confirm that vxdclid doesn't coredump.

8. Monitor the system for 1-2 hrs and if no further vxdclid coredumps are encountered during this time, then the plugin has resolved the issue.
