Installation/Upgrade Instructions - HP LeftHand P4000 - SAN Solutions Release Note

VSS Provider - Windows Server 2003
Windows Server 2008, all versions
DSM for MPIO - Windows Server 2003, SP1
If installing HP LeftHand P4000 DSM for MPIO into an existing Microsoft Cluster, use the following
steps.
1. First move all the resources from the node to be upgraded to another cluster node.
2. Pause the node on which you plan to install HP LeftHand P4000 DSM for MPIO, then proceed
with the installation on that node only.
3. The upgraded node will reboot, after which you can move the resources back.
4. Repeat steps 1 through 3 for each node.
Microsoft iSCSI Software Initiator - Recommended: Version 2.08 (or greater)
NOTE:
This has changed for 7.0 forward: When installing the Microsoft iSCSI Software Initiator version 2.08
(or greater), you must now install the Microsoft DSM if it is not present. The HP LeftHand P4000 DSM
for MPIO installer detects if the Microsoft DSM is missing and a message opens with instructions for
installing the MS DSM.
NOTE:
Important note about upgrading to version 2.08 (or greater) of the Microsoft iSCSI Software Initiator
If the DSM for MPIO is present on the system, you must use the following procedure to ensure a
successful upgrade.
1. Disconnect all volumes and iSCSI sessions before upgrading the Microsoft iSCSI Initiator.
2. After completing the upgrade, reconnect the volumes and reestablish the sessions.
Failure to follow this procedure can result in a loss of volume connectivity and the initiator installation
can stop responding. In this case, the installer cancel button does not work. Instead, you must use the
Task Manager to end the process for the initiator installer. Applications are likely to time out in this
scenario.
Once you have ended the installer process in the Task Manager, you can log into disconnected
volumes manually.

Installation/Upgrade Instructions

If you are upgrading to SAN/iQ software Release 8.1, and you are currently using any component
of the HP LeftHand P4000 Windows Solution Pack, the upgrade sequence differs slightly from the
upgrade sequence for upgrading the SAN/iQ software and the Centralized Management Console
(CMC) only.
For detailed instructions about upgrading the SAN/iQ software and the CMC, see the Release Notes
for version 8.1.
If you are running a previous version of the DSM for MPIO, the installer prompts you to first uninstall
that version before installing the current version.
