Systems and methods for booting from virtual volume spanned across unknown number of storage devices by constructing a virtual logical unit based on metadata of the storage resources and by responding to I/O commands with data associated with a dummy logical unit

An article of manufacture comprising:

• a non-transitory computer-readable medium;
• and
• computer-executable instructions carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system comprising a host processor and a plurality of physical storage resources communicatively coupled to the host processor via a bus, in order to facilitate booting from a virtual logical unit spanning the plurality of physical storage resources:
• 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
• 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.
