Verifying the data changes on the target
Now that you have modified some of the files, you want to be sure that the file modifications were applied correctly.
1. Browse your source and target. Compare the directory structures and the total number of files.
2. Look again at the four files you modified earlier. Verify manually that the changes you made have been applied to the
target copy of the file.
3. Right-click the connection on the right pane of the Management Console and select Verify. You will see two choices on
the Start Verification dialog box.
 Verify Only—This option performs the verification process by comparing the date, time and size of each file and
generates a verification report identifying the files that are not synchronized.
 Remirror Files to the Target automatically—This options performs the verification process by the comparison
method specified, generates a verification report, and then remirrors those files from the source to the target that
are not synchronized.
4. Select Verify Only and click OK.
Just like when you were monitoring the mirror and replication processes, you can monitor the verification process.
Notice that the
Mirror Status column changes to Verifying while the verification process occurs. When the verification
is complete, Storage Mirroring will have created a log file for you to review.
NOTE: Because of the way the Windows Cache Manager handles memory, machines that are doing minimal or light
processing, as you are in this evaluation, may have file operations that remain in the cache until additional
operations flush them out. This may make Storage Mirroring files on the target appear as if they are not
synchronized. When the Windows Cache Manager releases the operations in the cache on the source, the files
will be updated on the target. To make sure this does not impact your testing, flush the cache by copying a
couple of files from one directory to another and then deleting them.
