Before you begin the upgrade procedure

Before beginning the upgrade procedure, complete the following steps.

Step	Action
1	If you have not already done so, prepare your target system and environment as described in Preinstall or preupgrade procedure. This procedure consists of the following tasks: Backing up system resources and data Understanding SnapManager license options Understanding SnapManager COM server identity account requirements Understanding storage system requirements Understanding Windows host system requirements Note If you need to interrupt connectivity to the Exchange data when upgrading other components, such as storage systems or connection protocols, take Exchange offline. However, you do not need to stop Exchange services while you upgrade SnapManager; Exchange can continue to run while you upgrade SnapManager.
2	If you upgraded underlying SnapDrive or Microsoft iSCSI initiator versions to prepare your storage system for upgrading SnapManager, remove the iSCSI dependency with respect to SnapManager during the SnapManager upgrade process. There are two ways to do this: Run the SnapManager Configuration Wizard and use the Add Microsoft iSCSI Service Dependency screen to remove this dependency. Stop the Microsoft Exchange System Attendant resource service. Later, after you finish upgrading the SnapManager application, you can restore the dependency.

Upgrading in unattended mode

This topic describes how to upgrade SnapManager by running the software installation utility from a command line. This enables you to upgrade the SnapManager software under the control of a script for an unattended upgrade.

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	`SME3.2.exe` (the name of the software package itself)

How to start the unattended installation

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

CommandName /v"REINSTALLMODE=vomus REINSTALL=ALL
[/L* TempDirPath\LogFileName] /qb"

The following table describes each of the parameters.

Command or parameter	Description
CommandName	Either `setup.exe` or `SME3.2.exe`, depending on the SnapManager installation media being used.
`REINSTALLMODE=vomus`	Causes the software installation utility to recache the new software package.
`REINSTALL=ALL`	Causes the software installation utility to update all the software components.
`/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 Exchange is installed. The asterisk ("``") is a wildcard character that specifies 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:

For scenario 1, assume that you are installing from a CD inserted into the CD-ROM drive on E:\. In this case, you would enter the following at the command line:
E:\setup.exe /v"REINSTALLMODE=vomus REINSTALL=ALL /qb"
For scenario 2, assume that you are upgrading from the installation package downloaded to C:\NetApp\downloads\. In this case, you would enter the following at the command line:
C:\NetApp\downloads\SME3.2.exe /v"REINSTALLMODE=vomus REINSTALL=ALL /qb"
