    1. Introduction

    This document describes how to install version 7.2.0.0 of the IBM Storwize
    V7000.

    This release delivers fixes to resolve the APARs detailed in section 6.

    Please refer to the Recommended Software List and Supported Hardware List
    on the support website:

    http://www.ibm.com/storage/support/storwize/V7000

    -------------------------------------------------------------------------------

    2. Available Education

    A course on Storwize V7000 Planning and Implementation is
    available. For further information or enrolment, contact your local IBM
    representative.

    Visit the support website for online learning materials and tutorials,
    IBM Redbooks and training information.

    -------------------------------------------------------------------------------

    3. Pre-Requisites

    Before installing this software level please check the following
    pre-requisites are met. Also please note the concurrent upgrade (upgrade
    with I/O running) restrictions.

    Performance of the system will be degraded during the software upgrade
    process while node canisters are taken offline to perform the upgrade and
    the write cache is flushed when each node is restarted. IBM recommends
    you perform the upgrade at a time of lower overall I/O activity and when
    you do not expect significant spikes in the system workload.

    If you are performing a concurrent software upgrade, you must first ensure
    that all host paths are available and operating correctly.

    Check there are no unfixed errors in the event log or in the service GUI.
    Use normal service procedures to resolve any errors before proceeding.

    Before upgrading, IBM recommends using the software upgrade test utility
    "upgradetest". Refer to the following URL for further information:

    http://www.ibm.com/support/docview.wss?uid=ssg1S4000585


    If you are running a version of Storwize V7000 software older than 6.4.0.0
    then you will have to perform multiple upgrades to install the 7.2.0
    software on your system.

    Please see the following web page for the full upgrade compatibility
    matrix.

    http://www.ibm.com/support/docview.wss?uid=ssg1S1003705

    Note: Once an upgrade has completed, it is not possible to downgrade the
    software to an earlier level without deleting and manually rebuilding the
    system in its entirety, including restoring all volume data from an
    external backup.

    -------------------------------------------------------------------------------

    4. System Upgrade Information

    IMPORTANT: Systems with the 10 Gb/s Ethernet adapter will take longer to
    upgrade each node when installing 7.2.0 for the first time. This is due to
    an upgrade of the firmware on this adapter, and each node canister may take
    around 40 minutes to complete the upgrade. This additional delay will not
    affect systems upgrading from V7.2.0.x to a later release of 7.2.0.


    Global Mirror Relationships Must Be Stopped When Upgrading to V7.2.0
