Overview
This procedure describes how to install PowerPath on Windows Server
2003.
Note:This procedure is
specific to the installation of PowerPath versions 4.5 to 5.0, which is the
current shipping version for Windows 2003 hosts. For instructions on installing older
versions of PowerPath, refer to the applicable PowerPath installation manual
available on PowerLink.
This procedure is based on content from the following EMC manual:
This document can
be obtained from the EMC Powerlink website at:
You must be logged in as the Local System Administrator to proceed.
Verify the following prior to the installation of PowerPath:
·
Review
the patch ReadMe files to determine which patches (if any) you want to
install after PowerPath, and whether those patches have any added
prerequisites that must be met before you install PowerPath.
·
Determine
if the PowerPath software you are installing requires the removal or presence
of a previous version of PowerPath.
Some full versions require the previous version to be removed while
others do not. Also, some patches
require the full version to be present while others require it to be
removed. Refer to the PowerPath
Release Notes and/or PowerPath patch readme files for your specific version
to determine what needs to be present/removed and if and when a reboot is
necessary in order to install your specific PowerPath software version and/or
patch. These documents are available on http://Powerlink.EMC.com.
Note:A “failed redundancy” state can occur if
PowerPath is installedon a host with mirrored disks. This state only happens
if diskmanagement applications (that use the dmadmin service) arerunning when PowerPath is
installed. To prevent this, close all disk management applications(including diskmgmt.msc and diskpart.exe) and stop thedmadmin service before installing PowerPath.
If applicable,
stop all I/O and close all applications that access storage devices.

MPIO
framework considerations:
Note that PowerPath
4.6.x requires Microsoft MPIO framework 1.16 or later.
·
If
the MPIO framework is not installed on the host, the PowerPath 4.6.1
installer installs MPIO framework 1.16.; PowerPath 5.0.0 will install 1.17
·
If a
version of the MPIO framework less than 1.16 is installed on the host, the
PowerPath installer prompts you to upgrade to version 1.16. If you do not
upgrade, PowerPath installation aborts.
If a version of
the MPIO framework is greater than 1.16 is installed on the host, the
PowerPath installer notifies you and then continues with the installation.

|
Verify
single device paths:
Ensure that there
is only one logical connection per logical device. If necessary, disconnect
all additional HBAs/NICs, hubs, switches other than the primary
channels.
Note: Doing this prevents the host from seeing
the same LUN twice before PowerPath is configured.
|
|
Insert
the PowerPath CD-ROM:
Insert the
PowerPath installation CD in the CD-ROM drive and begin the installation. If autoplay is enabled, your browser launches and
displays the Getting Started page. You can install the software from the
Installation section by clicking the appropriate link for your operating
system. Then either:
|
|
Begin
Install:
In the Run
window, either browse to or enter the name of the PowerPath installation
program and click OK.
|
|
Continue
Install:
Complete the information as prompted on the next four
screens.
|
|
Select
your options:
Use the Destination
Folder screen to installPowerPath in a directory other than the default
directory (ifdesired).
Note: It’s best to install PowerPath in the
default directory as no additional action is required to install in the
default directory.
·
If
you are going to install PowerPath in itsdefault directory (recommended), clickNext and skip the remainder of this
step to continue with the next step below.
·
To
install PowerPath in a different (non-default) directory,click Change. The setup wizard prompts you
to browse toyour destination folder. Select the destination folder, and clickOK.
Caution:Do not specify the Windows System directory for yoursystem (specified by the %SYSTEMROOT% environmentvariable). PowerPath will not function correctly if it isinstalled in this directory. Click Next. |
|
Continue
Install:
In the Ready to Install the Program dialog
box, click Install.
Note:If you do not already have a license in
the registry, the EMCLicensing Tool displays.

Register
PowerPath
When prompted by
the EMC Licensing Tool, enter your PowerPath registration number in the License Key field. Click Add and then OK.
Note: The PowerPath registration numberis printed
on the License Key Card, which was delivered with the PowerPath media kit. You may enter multiple registration numbers
as PowerPath is supported on different storage systems. If you are upgrading
from a previous version, PowerPath saves the existing license key, and no
input is required.
Caution: Failing
to enter a registration number will result in the installation of PowerPath SE, which is the default policy without a
valid PowerPath license. If you fail to enter the registration number during
installation, it can be entered at a later point.
|
|
Finish:
Click Finish
in the next dialog box and
when prompted to reboot the host,click No.
Instead, from the
Start menu, select Shut Down and then click OK.
|
|
Reconnect
other I/O interfaces:
Reconnect the
additional HBAs/NICs, hubs, switches, etc. that you disconnected earlier.
|
|
Power
up boot:
Power up the
system. PowerPath is fully configured with multiple paths to logical devices
at boot up.
|
|
Check
for patches
If necessary, install any PowerPath patches from the
following URL:
http://powerlink.emc.com
Note: A readme file that explains how to install
the patch that accompanies every patch release. This file will also state whether you need
to reboot the host after the installation of the patch.
|
|
Verify
PowerPath sees new paths
The operating system must recognize new
paths before PowerPath can do so. Normally, no action is needed; the
operating system detects new paths automatically. Depending on the type of
HBA installed, you may have to scan for hardware changes in the device
manager. Alternately, reboot.
To verify that
PowerPath sees all new HBAs and paths to storage devices, use the following
command in the PowerPath utility:
powermt display dev=all
To test and validate any new path(s) with
PowerPath functionality, enter:
powermt restore
