Abstract
In accordance with embodiments of the present disclosure, an information handling system may include a processor and a plurality of physical storage resources communicatively coupled to the processor via a bus, the plurality of physical storage resources configured to, in order to facilitate booting from a virtual logical unit spanning the plurality of physical storage resources: (i) after enumeration of the plurality of physical storage resources, construct the virtual logical unit based on metadata of the plurality of physical storage resources; and (ii) prior to construction of the virtual logical unit, respond to input/output commands from an operating system of the information handling system with data associated with a dummy logical unit or with an indication that the dummy logical unit is busy.
