Installing or Upgrading the iSCSI Software Initiator

Use this procedure to install or upgrade the Microsoft iSCSI Software Initiator.

Steps

1. Stop the SnapDrive for Windows service.
2. If you are running SnapManager for Microsoft Exchange, stop any application-specific services that have iSCSI dependencies (for example, Microsoft Exchange System Attendant).
   Note: You can also remove iSCSI dependencies using SnapManager for Microsoft Exchange Configuration Wizard; however, this option is not recommended and should only be used if you are unable to stop the application-specific services.
3. Perform the following steps to install the new iSCSI Software Initiator components.

   If you are installing or upgrading a cluster, first close MMC, then install the new iSCSI Software Initiator components on each node, starting with the nodes that do not own the cluster resources and rotating which system is the owner until all nodes in the cluster have the new iSCSI initiator installed.

   1. Download the Microsoft iSCSI Software Initiator from the Microsoft site.
   2. Run the install package executable and proceed through the Installation wizard.
   3. If you are going to use the iSCSI Initiator to create and manage LUNs, make sure that the Initiator Service and Software Initiator check boxes are selected on the Installation Options screen.
      Note: The Virtual Port Driver option is unavailable because it is automatically installed during the Microsoft iSCSI Initiator installation and upgrade.
   4. If you want to use MPIO, check the Microsoft MPIO Multipathing Support for iSCSI check box on the Installation Options screen.
   5. Follow the prompts to complete the installation.

   For more information about installing and configuring the Microsoft iSCSI Initiator, see the iSCSI Microsoft Windows Initiator Support Kit Setup Guide document on the NOW site.

4. Restart the SnapDrive service on the stand-alone host or on each node in the cluster
