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

8. Known Issues and Restrictions in this Level
It is not supported to shrink the size of a compressed volume in 7.2.0.0
If using IP replication, please review the set of restrictions published in
the V7.2 Configuration Limits and Restrictions document.
Moving Volumes to Another I/O Group Without Stopping Host Activity is Not
Supported for All Operating Systems
http://www.ibm.com/support/docview.wss?uid=ssg1S1004125
Intra-Cluster Global Mirror Not Supported
Refer to the following flash for more information on this restriction:

Use of a standards-compliant browser, such as Firefox, is recommended for
using the SVC Management GUI. Use of Internet Explorer is supported but
may result in slower performance of the GUI.
