The installation and use of this utility is nondisruptive, and does not require restart of any IBM  Storwize V7000 nodes. Therefore, there is no interruption to host I/O. The utility is only  installed on the current configuration node. System administrators must continue to check whether the version of code that they plan to  install is the latest version. For the most current information, see this website. This utility is intended to supplement rather than duplicate the tests that are performed by the  IBM Spectrum Virtualize update procedure (for example, checking for unfixed errors in the  error log). Concurrent software update of all components is supported through the standard Ethernet  management interfaces. However, most of the configuration tasks are restricted during the  update process. 13.4.3 Updating your Storwize V7000 to V8.2.1 To update the IBM Spectrum Virtualize software to V8.2.1, complete the following steps: 1. Open a supported web browser and navigate to your cluster IP address. A login window  opens (see Figure 13-11).
