Abstract
A technique evaluates moving a logical unit of storage (LUN). The technique involves adding, while a host accesses a production LUN on a source array, a test LUN on a target array. The technique further involves duplicating host input/output (I/O) requests from the host to form a first set of the host I/O requests for processing on the production LUN on the source array and a second set of the host I/O requests for processing simultaneously on the test LUN on the target array. The technique further involves performing, while the first set of the host I/O requests are processed on the production LUN and the second set of the host I/O requests are processed simultaneously on the test LUN, a performance evaluation on the target array to assess a performance outcome of moving the production LUN from the source array to the target array.
