These keys are normally SM-generated but the field has zero key validation and zero RBAC. Forged SCSI identities persist in the XAPI database and propagate through snapshot, clone, and pool join operations. Downstream systems (backup tools, Windows guest drivers, inventory scanners) that rely on SCSI identity metadata for disk identification may misidentify disks."
