      Description

      We set up the three node SCM HA cluster for test purpose.

      From ozone dbug ldb tool, we found that the localIDs are not same between the three SCM. The reason is due to localID, which is initialized based on each machines own timestamp. 

      The ldb result fetch from scm.db on 3 SCMs.
