Cause
The vxdclid plugin didn't interact properly with these versions of VxVM and VRTSsfmh.
Resolution
A new vxdclid plugin has been created to fix this issue 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.
