Advanced Setting Description
Error Recovery Level 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.
Initial R2T 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.
Immediate Data 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.
Data PDU In Order 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.
Data Sequence In 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.
Primary Header Digest Method Primary header digest used by the volume. Choices are:

No Digest (default)

CRC32C
Secondary Header Digest Method Secondary header digest used by the volume. Choices are:

No Digest

CRC32C (default)
Primary Data Digest Method Primary data digest used by the volume. Choices are:

No Digest (default)

CRC32C
Secondary Data Digest Method Secondary data digest used by the volume. Choices are:

No Digest

CRC32C (default)
