Luns in mass storage function are identified using their id. While creating lun's directory user cannot choose any arbitrary name other than decimal value from 1 to FSG_MAX_LUNS. Moreover, LUNs ids should be contiguous. This means that user may remove only lun with max id and can create new lun only if its id equals to max id + 1.
