This object reports the code set, such as binary or ASCII, used to encode this logical unit's device identifier, taken from the Identification Descriptor within the LU's Device Identification VPD page. Management or inventory software needs this value to correctly decode ciscoScsiLuIdValue: reading identifier bytes as ASCII when the code set says binary would produce garbage in an inventory report. A code set of binary tells a polling script to render ciscoScsiLuIdValue as hex bytes rather than attempt to print it as text.
