 Header Digest enables header digest on the initiator to protect the
integrity of the iSCSI header. The target must accept the header digest
during parameter negotiation.
 Data Digest enables data digest on the initiator to protect the integrity
of the iSCSI data. The target must accept the data digest during
parameter negotiation.
 ImmediateData and InitialR2T. Table 4-2 describes how
ImmediateData and IntialR2T combine to determine how the initiator
can send immediate data.
 Snack enables the initiator to request retransmission of numbered
responses, data, or R2T PDUs from the target.
 Logout on Discovery Session enables issuing a logout after
completing the discovery session (default).
 Strict iSCSI Login enables strict iSCSI login, in which the adapter
adheres to the iSCSI login rules, and therefore cannot operate with
devices that do not conform to these rules. When disabled, the iSCSI
login rules are relaxed, and the adapter can operate with devices that
do not conform to these rules.
 Error Recovery Level currently supports only error recovery level 0.
