Understanding the SnapManager Configuration Wizard

The primary function of the Configuration Wizard is to migrate Exchange databases to Data ONTAP LUNs so that the databases can be backed up and restored using SnapManager. For more information, go to any of the following topics:

What the Configuration Wizard does

The Configuration Wizard enables you to move your Exchange data in the following ways.

From local disk to LUN

To enable management by SnapManager.

If Exchange databases need to be moved, the wizard dismounts the databases in a storage group, moves the Exchange database and transaction log files to the selected LUN, and remounts the databases.
Note
SnapManager takes Exchange databases offline during the move operation.
The wizard creates a SnapInfo directory that SnapManager uses to store information about the backup sets and the backed-up transaction logs.
The wizard disables circular logging for all storage groups that are moved to a LUN, to enable up-to-the-minute recovery of those storage groups.
The wizard also guides you through several application settings. These settings include enabling notification of SnapManager events using e-mail, and enabling notification of SnapManager events using the storage system Syslog or the AutoSupport feature.

From LUN to LUN

If resource management issues require this. For example, consolidating Exchange on another storage system.

From LUN to local disk

If no longer managed using SnapManager. However, this is not supported in MSCS configurations.

When to use the Configuration Wizard

You can use the Configuration Wizard in the following situations.

For initial configuration

Before you can use SnapManager to back up and restore an Exchange data store, you must use the SnapManager Configuration Wizard to migrate the databases and transaction logs from your Exchange servers to the LUNs you configured on your storage system with SnapDrive.

To view or change the database configuration

After the initial configuration, you can rerun the Configuration Wizard at any time to review or make changes to your Exchange data store configuration.

To validate the database configuration

If you add databases or move databases to different LUNs without using SnapManager, run the Configuration Wizard to ensure that the databases are stored in valid locations and to create a mapping between those databases and their respective SnapInfo subdirectories.

Attention
Use the SnapManager Configuration Wizard to move Exchange databases, transaction logs, or storage group system files. SnapManager ensures that these files are place in locations that meet SnapManager configuration requirements. Incorrectly located Exchange database, transaction logs, or storage group system files impairs SnapManager operation. If Exchange System Manager is used to move Exchange database, transaction logs, or storage group system files, run the SnapManager Configuration Wizard after the operation to ensure that these files are in correct locations.

About the Exchange and SnapManager components

When you use the Configuration Wizard, you are specifying the placement of several components of Exchange and SnapManager:

Storage group system path

Path to the directory that contains the Exchange storage group system files. SnapManager places storage group system files on the same LUN that stores the transaction logs for that storage group. The storage group system files must remain where the Configuration Wizard places them.

Storage group databases

The databases in a storage group or store.

Database

The paths for the .edb and .stm files for the Exchange database. The .edb file stores message and attachment content generated by MAPI clients, and message properties such as author, recipients, subject, and priority. The .stm file holds native Internet content (for example, MIME).

Transaction log files

The location of the Exchange transaction logs. The transaction logs contain changes made to the Exchange databases since the last backup, enabling an up-to-the-minute restore.

SMTP queue path

The directories used by the SMTP queue.

MTA queue path

The directories used by the MTA queue.

SnapInfo directory

Contains SnapManager backup information, copies of transaction log files, and other data critical to the backup set.

Viewing the placement of Exchange and SnapManager components

To view the current placement of the Exchange and SnapManager components, you can use the Configuration Wizard or the Backup and Verification tab.
