Description
The level of error recovery that the initiator and the target negotiated. Higher
numbers represent more elaborate recovery schemes. Choices are:
0 = session recovery class (default)

1 = digest failure recovery

2 = connection recovery class

For more information, refer to the iSCSI specification.
Indicates whether the initiator must wait for a R2T request before sending data to
the target. Choices are:
Enabled =- the initiator must wait for a R2T request before sending data to the

target. (default)
Disabled - the initiator can send unsolicited data within limits that the value of

First Burst Length specifies.
Indicates whether the initiator and target have agreed to allow the transmission of
immediate data in the session. (Immediate data is data that the initiator
piggybacks onto an iSCSI command PDU.) Choices are:
Enabled = the initiator and target have agreed to allow the transmission of

immediate data in this session. (default)
Disabled = the initiator and target have not agreed to allow the transmission of

immediate data in this session.
Indicates whether the data PDUs within a sequence of data PDUs must be located
at continuously increasing addresses. Choices are:
Enabled = the data PDUs within a sequence of data PDUs must be located at

continuously increasing addresses, with no gaps or overlay between PDUs.
(default)
Disabled = the data PDUs within each sequence can be in any order.

Indicates whether sequences of data PDUs must be transmitted by using
continuously increasing offsets, except during error recovery. Choices are:
Enabled = sequences of data PDUs must be transmitted by using continuously

increasing offsets, except during error recovery. (default)
Disabled = sequences of data PDUs can be transmitted in any order.

This value indicates the ordering of the sequences themselves, not the ordering of
the data PDUs within each sequence. The Data PDU In Order setting indicates the
ordering of the data PDUs within each sequence.
