During the synchronization process, you can see the status by using the 
lsvdisksyncprogress command. 
As shown in Example 7-9 on page 296, the first time that the status is checked, the 
synchronization progress is at 48%, and the estimated completion time is 161026203918. The 
estimated completion time is displayed in the YYMMDDHHMMSS format. In our example, it is 
2016, Oct-26 20:39:18. When the command is run again, the progress status is at 100%, and 
the synchronization is complete.
