Uninstalling SnapManager

This section describes how to uninstall the SnapManager software. See the following topics for more information:

Note
Unless it is specified for a particular upgrade path or for a particular troubleshooting situation, you do not need to uninstall SnapManager before reinstalling it or upgrading to a newer version.

Before you uninstall SnapManager

If you have used SnapManager to manage your SQL Server databases and you plan to reinstall SnapManager later, be sure to record the drive letter and path of the SnapInfo directory locations before you uninstall SnapManager.

Single SnapInfo directory

If you have set up a single SnapInfo directory for all databases on this host, then record the drive letter and path of the LUN that contains a single SnapInfo directory for all SQL Server instances and their associated databases.

Advanced SnapInfo directories

If you have set up multiple SnapInfo directories, then record the following information:

The drive letter and path of the LUN that contains the default SnapInfo directory for all SQL Server instances
The drive letter and path of any LUN that contains the default SnapInfo directory for one or two LUNs shared by multiple databases (if configured)
The drive letter and path of any LUN that contains the SnapInfo directory for an individual database (if configured)

SnapManager Reports records the current SnapInfo directory locations in the most recent logs contained in the Backup folder and in the Config folder.

After you reinstall SnapManager, be sure to reconfigure SnapManager with the same SnapInfo directory locations that were used by SnapManager previously.

Attention
If you configure SnapManager with different SnapInfo directory locations than used previously, then SnapManager will no longer have records of any backups taken before the reinstallation of SnapManager occurred. As a result, your prior backup sets could be invalidated or deleted the next time you perform a backup operation.

Comparison of the two uninstallation modes

The software installation utility for SnapManager can be run in either interactive mode or unattended mode. These two modes are described in the following table.

Comparison	SnapManager uninstallation mode
Comparison	Interactive	Unattended

Step	Action
1	If SnapManager is running, close it. Note You do not need to stop SQL Server or remove the SQL Server databases from the LUNs before you uninstall SnapManager. SQL Server will continue to run during the uninstallation process and after the uninstallation is completed.

Uninstalling SnapManager in unattended mode

This topic describes how to uninstall SnapManager using the software installation utility in unattended mode. This enables you to uninstall SnapManager under the control of a script for an unattended uninstallation.

Note
You can also uninstall SnapManager in unattended mode, as described in Uninstalling SnapManager in interactive mode. For a comparison of the two uninstallation modes, see Comparison of the two uninstallation modes.

How to invoke the software installation utility

The command name you specify depends on the SnapManager installation media you will be accessing.

SnapManager installation media	Application name to be run
Software CD	`setup.exe` (located on the CD-ROM)
Software package downloaded from the network	`SMSQL2.1.exe` (the name of the software package itself)

What to specify in the command-line

To install SnapManager in unattended mode, enter the following command either directly at the command- line or through a script:

CommandName /v"REMOVE=ALL [REMOVEREPORTFOLDER=1] [/L* TempDirPath\LogFileName] /qb"

The following table describes each of the parameters.

Command or parameter	Description
CommandName	Either `setup.exe` or `SMSQL2.1.exe`, depending on the SnapManager installation media being used.
`REMOVE=ALL`	Causes the software installation utility to remove SnapManager (as if you selected the Remove option in the Program Maintenance screen).
`REMOVEREPORTFOLDER=1`	Optional. Causes the software installation utility to remove the Report folder (as if you selected the Remove Report Folder option in the Remove the Program screen).
/L* TempDirPath\LogFileName	Optional. If you specify this option, detailed information about the installation will be written to the specified log file. This information can be used to investigate details about how a particular instance of SnapManager for Microsoft SQL Server is installed. The asterisk ("``") is a wildcard character specifying that all of the installation information (such as status messages, nonfatal warnings, and error messages) should be logged. TempDirPath* is the fully qualified name of the directory in which the installation log will be created or overwritten. LogFileName is the name of the file to which the installation information will be written.

Examples

Consider the following two scenarios.

Installation details	Scenario 1	Scenario 2
Installation media to be used	CD inserted into the CD-ROM drive on `E:\`	Installation package downloaded to `C:\NetApp\downloads\`
SnapManager license	Filer-side	Server-side (license key `ABCDEFGHJIJKLMN`)

For scenario 1, enter the following at the command-line:

E:\setup.exe /v"REMOVE=ALL /qb"

For scenario 2, enter the following at the command-line:

C:\NetApp\downloads\SMSQL2.1.exe /v"REMOVE=ALL REMOVEREPORTFOLDER=1 /qb"
