Introduction This document contains important information about version 1.5.2.3 of the IBM Storwize V7000 Unified software. ---------------------------------------------------------------------------------- 2. Prerequisites Software Upgrade Test Utility: The software upgrade test utility "upgradetest" must be run within two hours of starting the upgrade. The upgrade test utility can be run as many times as required, but there must be a successful run of the upgrade test utility within two hours of starting the upgrade. Refer to the following URL for further information: http://www.ibm.com/support/docview.wss?uid=ssg1S4000986 Concurrent Upgrades: The concurrent upgrade (upgrade with I/O running) restrictions are documented at the following URL: http://www.ibm.com/support/docview.wss?uid=ssg1S1004680#_Restrictions_Upgrade If you are performing a concurrent code upgrade, first ensure that all host paths are available and operating correctly. System Performance: Performance of the IBM Storwize V7000 Unified will be degraded during the software upgrade process. IBM recommends you perform the upgrade at a time of lower overall I/O activity and when significant spikes in the system workload are not expected. Event Checking: Check there are no unfixed events in the event log. Use normal service procedures to resolve any events before proceeding. Asynchronous Replication Systems: If the system is part of an asynchronous relationship (either source or target), stop the replication to avoid asynchronous replication failures during upgrade. Full upgrade compatibility matrix: Please see the following web page for the full upgrade compatibility matrix. http://www.ibm.com/support/docview.wss?uid=ssg1S1003918 ------------------------------------------------------------------------------------- 3.
