Abstract
Methods, systems, and computer programs encoded on computer storage medium, for identifying storage devices of an IHS, wherein a BIOS of the IHS is associated with a first enumeration order of the storage devices; enumerating the storage devices such that a particular storage device of the storage devices is enumerated as the first enumerated storage device for both the BIOS and an OS of the IHS, including: determining that an OS installation mode is enabled, and in response, i) exposing only the particular storage device, and ii) disabling the remaining storage devices to; determining that a LUN is set by the BIOS as the first enumerated storage device, including setting an unique identifier (UID) for the particular storage device, and in response fetching data associated with the LUN based on the UID; parsing the LUN data; assigning, based on the parsing, the LUN as the first enumerated storage device.
