This OID is a true/false flag indicating whether this local-disk configuration is protected from being overwritten when the server is reassociated with a different service profile. This protection setting matters to an admin because, if set true, it preserves existing RAID or data configuration on the physical disks even when the profile changes, preventing accidental data loss during profile reassignment. Before moving a service profile with existing data disks to a new blade, an admin would check this flag to make sure local disk data will not be wiped by the profile association.
