How Verification Works
To better understand how Storage Mirroring verification works, the following diagram identifies the steps involved with the
Storage Mirroring verification process. Each numbered step is described below the diagram.
1. Verification is initiated by the Storage Mirroring administrator, either manually through one of the clients or
automatically through a scheduled verify.
2. Storage Mirroring compares the date, time, and size of files on the source to the files on the target and determines
which files are not identical. Also, you can select the option to have Storage Mirroring perform a checksum calculation
on all Storage Mirroring files regardless of the date, time, and size.
3. A verification log file is created which details what was verified as well as which files are not synchronized.
4. If a remirror is specified, Storage Mirroring transmits only the dissimilar data by the remirror options chosen, newer on
source or checksum.
5. As each packet of mirror data is received on the target, the target returns an acknowledgement to the source confirming
that the mirrored data has been received.
