Error description

          NOTE: If this program is terminated before the
  completion due to
          a system crash or ctrl-C, and you want to
  continue afterwards
          execute the following command
          replacepv -R /tmp/replacepv12976316
  0516-015 lmigratelv: The migrate was done but the
  partition
          could not be resynced.
  0516-1227 replacepv: Warning, replacepv did not
  completely succeed.
  

Local fix

Problem summary

• Replacepv has some faulty logic to try and validate that it has
  successfully mirrored an LV onto the new replacement disk.
  So when you are replacing a bad disk that has stalepps (would
  not be uncommon), replacepv will create a copy of each LV onto
  the new disk, sync, and then verify.
  When it verifies, it sees that the copy on the bad disk is
  still stale, so it warns that the LV may not be fully migrated,
  but still removes the copy of the bad disk, and then
  fails out of replacepv without migrating any remaining LVs
  to the new disk.
  .
  You'll see the warnings above, and see that one LV was
  successfully moved to the new disk, but if you had any other
  LVs on the bad disk, they would not be moved.
  

Problem conclusion

• Correct the validation part of replacepv so that it will not
  warn/fail if the LV is not fully syncd, so long as the new copy
  on the new disk is sync'd.
  .
  This will allow replacepv to continue migrating the rest of
  the LVs to the replacement disk.
