Introduction This document contains important information about version 1.6.2.9 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=ssg1S1005471#_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 is 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. Refer to the following technote link to prepare for actions to be taken post upgrade if applicable http://www.ibm.com/support/docview.wss?uid=ssg1S1009686 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.

Known Issues and Restrictions in this Level * IBM Storwize V7000 Unified systems configured with Callhome need to upgrade to V1.6.2.4 or later prior to 2020 in order to apply ECC (Electronic Customer Care) trust list file V4 that includes the updated server certificates. Refer to the below technote for more information on this issue: https://www.ibm.com/support/pages/ibm-storwize-v7000-unified-ecc-electronic-customer-care-trust-list-file-upgraded-v4 * In IBM Storwize V7000 Unified systems with V1.6.2.0 and onwards, to address security vulnerability as per CVE 2016-2183, cipher 'arcfour' is disabled by default. This would result in async replication for filesystem configured with 'fast' encryption method to fail and action needs to be taken to restore the function. Refer to the below technote for more information on this issue: http://www.ibm.com/support/docview.wss?uid=ssg1S1009686 * After upgrade, NDMP backups may start failing and may not get resolved even by restarting the NDMP backup jobs. Please contact IBM support for further assistance or refer to the below technote for more information on this issue: http://www-01.ibm.com/support/docview.wss?uid=ssg1S1009338 * SMB 1.0 is deprecated from current and all future versions of IBM Storwize V7000 Unified. NOTE: SMB 1.0 still works on all versions of IBM Storwize V7000 Unified. * SMB protocol version restrictions (max_protocol parameter) : * Systems upgrading from 1.5.x.x code level to 1.6.0.1, or later will have SMB 3.0 (max_protocol parameter) disabled by default. Enabling SMB 3.0 on the V7000 Unified requires a change window with an outage as it is a non-concurrent procedure requiring specific actions to be taken on the windows client side. For further details please contact IBM support. * Systems which are first time installed with 1.6.0.0 or later code levels will have SMB 3.0 (max_protocol parameter) enabled by default and can be used without any restrictions. * Systems upgrading from 1.6.0.0 to this code level will have SMB 3.0 (max_protocol parameter) enabled by default and may be used without any restrictions. * In IBM Storwize V7000 Unified, Windows 8 with offline folders is not currently supported. * Browsers with below listed levels are certified for using the IBM Storwize V7000 Unified Management GUI. Mozilla Firefox 38 Mozilla Firefox Extended Support Release (ESR) 38 Important: All Firefox users should upgrade to these updated packages, which contain Firefox version 38.x ESR. After installing the update, Firefox must be restarted for the changes to take effect. For Red Hat Linux users, make sure all previously released errata relevant to your system have been applied before applying this update. This update is available at the Red Hat Network: https://rhn.redhat.com/errata/RHSA-2015-1982.html Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 Microsoft Internet Explorer (IE) 10 and 11 Google Chrome 41 Later versions of the browsers are supported as long as the vendors do not remove or disable functionality that the product relies upon. For browser levels higher than the levels that have been certified with the product, customer support will accept usage-related and defect- related service requests. As with operating system and virtualization environments, if IBM support cannot recreate the issue in our lab, we may ask the client to recreate the problem on a certified browser version in order to determine if a product defect exists. Defects will not be accepted for cosmetic differences between browsers or browser versions that do not affect the functional behavior of the product. If a problem is identified in the product, defects will be accepted. If a problem is identified with the browser, IBM may investigate potential solution or work-around that the client may implement until a permanent solution becomes available. * In IBM Storwize V7000 Unified, quarantined folders are only accessible with the root ID. This restriction will be lifted in a future IBM Storwize V7000 Unified release. Refer to the below technote for more information on this issue: http://www-01.ibm.com/support/docview.wss?uid=ssg1S1004078 For more details please refer to the V1.6 Configuration Limits and Restrictions for IBM Storwize V7000 Unified for product restrictions that currently apply: http://www.ibm.com/support/docview.wss?uid=ssg1S1005471 * If using IP replication, please review the set of restrictions published in the V7.6 Configuration Limits and Restrictions document. * Intra-Cluster Global Mirror Not Supported Refer to the following flash for more information on this restriction: http://www.ibm.com/support/docview.wss?uid=ssg1S1003725 * SAN Volume Controller Inter-cluster Metro Mirror and Global Mirror Compatibility Cross Reference Refer to the following flash for more information on this restriction: http://www.ibm.com/support/docview.wss?uid=ssg1S1003646 Once the software upgrade process has been started, the management GUI automatically refreshes to display the progress of the upgrade. During the upgrade each file module will be restarted, resulting in a fail-over and fail-back of the management services, including the GUI. After a fail-over has occurred it may be necessary to manually refresh/reload the page in the web browser in order to reconnect with the new active management node and login again. If an IBM Storwize V7000 Unified Code Upgrade Stalls or Fails then contact IBM Support for further assistance http://www.ibm.com/support/docview.wss?uid=ssg1S1002894 -------------------------------------------------------------------------------------- 7.

HU01203 After upgrade to 1.6.0.x remote admin users authenticated with AD server were unable to login to the system CLI or GUI. HU01204 Users were not able to access the shares due to snapshot related deadlock in GPFS. This exposure exists after upgrade to V1.6.0.x when snapshots created on V1.5.x and V1.6.0.x coexist on the system. HU01129 Client unable to access the system because of CTDB unhealthy on all nodes. HU01150 Process smbd terminates after CTDB timeout. HU01133 NFSv4 server exits on locks out of sync causing NFS services to stop.
