ZAPC-TKN-PARALLEL-SESS-LU
specifies whether or not the partner LU supports parallel sessions. A value of
ZSPI-VAL-TRUE indicates that partner LU is a parallel-session LU (or supports
parallel sessions). A value of ZSPI-VAL-FALSE indicates that the partner LU is a
single-session LU; therefore, the local LU will neither initiate nor expect any
CNOS commands.
The PARALLEL-SESS-LU token has the token type ZSPI-TYP-BOOLEAN. The
programmatic commands that use this token include ZCOM-CMD-ADD, ZCOM-
CMD-ALTER, and ZCOM-CMD-INFO. The valid object type for this token is
PTNR-LU.
When used with ZCOM-CMD-ADD, the default value of this token is ZSPI-VAL-
FALSE. When used with ZCOM-CMD-ALTER, the PTNR-LU object must be in
the STOPPED state. This token is always returned in the ZCOM-CMD-INFO
response buffer.
ZAPC-TKN-PERIPHERAL-NODE
specifies whether the partner LU resides on a peripheral node or a subarea node.
If the value of the PERIPHERAL-NODE token is ZSPI-VAL-TRUE, the partner LU
resides in a peripheral node. If the partner LU is not a parallel-session LU, the
partner LU is also a secondary LU (SLU).
If the value of the PERIPHERAL-NODE token is ZSPI-VAL-FALSE, the partner
LU resides on a subarea node. If the partner LU is not a parallel-session LU, the
partner LU is also a primary LU (PLU).
If the partner LU is a parallel-session LU, the partner LU’s role (SLU or PLU) is not
indicated.
The PERIPHERAL-NODE token has the token type ZSPI-TYP-BOOLEAN. The
programmatic commands that use this token include ZCOM-CMD-ADD, ZCOM-
CMD-ALTER, and ZCOM-CMD-INFO. The valid object type for this token is
PTNR-LU.
When used with ZCOM-CMD-ADD, the default value is ZSPI-VAL-FALSE. When
used with ZCOM-CMD-ALTER, the PTNR-LU object must be in the STOPPED
state. This token is always returned in the ZCOM-CMD-INFO response buffer.
