echo This batch script will confirm that the lag time on SnapMirrors
echo on the R200 are not older than 4 hours. Anything older indicated
echo a problem with the SnapMirror process.
echo.
echo Due to a limitation with looping logic in batch files, this script
echo will alert and report only 1 instance of a lagging snapmirror. If
echo multiple lagging snapmirrors exist you'll notice this in the log file
echo anyway.
echo.
echo This script must run against both filers and the near store to
echo produce a complete report.
