This read-write enumerated value (true, false) sets this node's DataSequenceInOrder preference, where false allows iSCSI data PDU sequences to be transferred in any order and true requires continuously increasing offsets except during error recovery. An admin may need to check this setting when troubleshooting reordering-related performance or compatibility issues between an initiator and target with mismatched preferences. For example, a target requiring true (in-order sequences) paired with an initiator trying to negotiate false could affect how a large multi-connection transfer is scheduled.
