Transitioning from Toolscenter to Xclarity Essentials
Transitioning from ToolsCenter to XClarity Essentials Why Transition While Lenovo is committed to innovate and deliver the best software tools for managing our new generation of servers, we’re also making an effort to maintain backward compatibility with previous generations of servers and software to protect your existing assets. Lenovo XClarity Essentials toolset provides the latest and greatest capabilities for managing Lenovo ThinkSystem, System x and ThinkServer. XClarity Essentials was built on the Lenovo ToolsCenter foundation and will replace it going forward. Backward compatibility is maintained in two ways: 1. All XClarity Essentials tools and commands support the new ThinkSystem and Lenovo System x from the M4/M5 and X5/X6 generations, and have partial support for ThinkServer also. 2. Customers using Lenovo ToolsCenter tools or IBM ToolsCenter tools can migrate to XClarity Essentials commands with very small effort. This is the focus of this document. If you have existing automation assets that you want to preserve and refresh to XClarity Essentials command syntax to support your existing servers and the new ones, please read on. XClarity Essentials toolset is also updated to access the latest Lenovo infrastructure such as acquiring firmware updates and linking to online documentation. The existing ToolsCenter will remain available to IBM brand systems. The existing ToolsCenter will continue to direct you to resources on the IBM infrastructure. If you prefer to keep your existing assets intact then you are not obligated to
