Use vxplex to detach and then re-attach the plex.
# vxplex -g
# vxplex -g
When the plex is re-attached to volume, it will be resynchronized. The volume remains online during a resynchronization, but this may have an impact on disk I/O performance until the resynchronization is complete.
Use vxtask to monitor the resynchronization status:
# vxtask -l list
