This release of software is a service release and delivers fixes to resolve the APARs detailed in section 5. Please refer to the Recommended Software List and Supported Hardware List on the support website: http://www.ibm.com/systems/hk/storage/disk/storwize_v5000 ------------------------------------------------------------------------------- 2. Available Education 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 Please see the following web page for the full upgrade compatibility matrix. http://www.ibm.com/support/docview.wss?uid=ssg1S1004336 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.
