ZFSM–SBI
reports the SNAX/HLS implementation of FSM_SBI. This FSM enforces the stop–
bracket–initiation protocol. It is used only for LU session type 6.1. When
interpreted in the ZHLS–MAP–STATUS–SESS–SEND token, this field refers to the
sender of the SBI request. When interpreted in the
ZHLS–MAP–STATUS–SESS–RECV token, it refers to the receiver of the SBI
request. This field can have the following enumerated values:
ZHLS–VAL–FSM–SBI–NOBB
indicates that the response to the SBI request has been processed. The implied
half session has agreed not to begin any new brackets.
ZHLS–VAL–FSM–SBI–NULL
indicates that this FSM is not yet initialized or is not used in the current
session.
ZHLS–VAL–FSM–SBI–P–NOBB
indicates that a positive response to an SBI request has been processed. The
implied half session might continue to begin brackets, although it has been
asked to stop doing so.
ZHLS–VAL–FSM–SBI–RESET
indicates that no SBI–initiated quiesce operation is in progress; the implied
half session can continue to begin brackets.
