Introduction This document describes how to install version 6.1.0.2 of the Storwize V7000 (2076) software. 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 Storwize V7000 Upgrade Information Before installing this code level please check the following pre-requisites are met. Also please note the concurrent upgrade (upgrade with I/O running) restrictions. Performance of the Storwize V7000 will be degraded during the software upgrade process because node canisters are taken offline to perform the upgrade and the write cache is flushed when each node canister 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 code upgrade, you must first ensure that all host paths are available and operating correctly. Check there are no unfixed events in the event log. Use normal service procedures to resolve these events before proceeding. Before upgrading the Storwize V7000, we recommend using the software upgrade test utility "upgradetest". Refer to the following URL for further information: http://www.ibm.com/support/docview.wss?uid=ssg1S4000585 Please see the following web page for the full upgrade compatibility matrix. http://www.ibm.com/support/docview.wss?uid=ssg1S1003705 ------------------------------------------------------------------------------- 4.
