Enabling Windows basic failover
Basic Multipath Input Output (MPIO) failover capability is
supported in Microsoft Windows 2000 and Windows
Server 2003 (32-bit and 64-bit) operating system environments.
Note:
These instructions assume that installation of the SAN and the
MSA is complete. Refer to information shipped with the server,
switch, and MSA for installation and configuration information.
Clustered and non-clustered server environments must install these
multipathing components on each server with access to the MSA.
Components (and installation instructions) described in this section
are obtained from links provided in MSA web sites.

MSA1500 cs web site:
1. Verify that other multipathing software, such as Secure Path,
is not present on the system.
If other multipathing software is currently installed, do not
proceed with these instructions.
Either continue using your previous solution, or completely
uninstall that solution from your environment.
2. Verify that MSA controller firmware that supports basic
multipathing is installed on your MSA.
MSA1000: 4.32 or later
MSA1500 cs: 4.82 or later
To determine the current version of installed MSA firmware,
scroll through the messages on the controller LCD panel,
until the firmware version is displayed.
If an update is necessary, obtain and install new firmware
from the Software, Firmware & Drivers page of the MSA
web site.
3. Verify that the currently supported HBA firmware and driver
is installed on each server.
To determine the latest supported HBA firmware and driver
versions, refer to the MSA Compatibility Guide, available on
the MSA web site.
To determine the currently installed HBA firmware and driver
versions, either view the server monitor during the startup
process or view the SCSI and RAID Controllers information
in Device Manager.
If an update is necessary, obtain and install the HBA
components from the link on the Software, Firmware &
Drivers page of the MSA web site.
Note: If using the STORport driver, obtain and install the latest
operating system patch from the Microsoft web site:
http://www.microsoft.com. Refer to KB article 838894.
4. Verify that only the primary path (connected to the I/O
module behind controller1) is connected between the server
and the MSA.
During the installation procedure of the next step, only one
path to the storage can be visible.
If necessary, disconnect the cables to the redundant path.
