The MIB's DESCRIPTION for cucsLsBindingRestrictMigration is only the auto-generated stub 'Cisco UCS ls:Binding:restrictMigration managed object property', but the 'restrictMigration' property name together with its TruthValue type tell us this column, on the record of a service profile being bound (associated) to a specific physical blade or rack server, holds the restrictMigration as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The restrictMigration TruthValue controls whether this service profile is locked to its currently bound server and forbidden from migrating to a different one in the pool, a safeguard for workloads that shouldn't silently move hardware. Setting restrictMigration true on a binding prevents UCS Manager from automatically reassigning that service profile to a different blade even if the current one needs maintenance.
