Considerations for Dynamically-Added and Parallel-Session PTNR-
MODE Objects
Upon receipt of an unsolicited BIND request, the SNAX/APC process will first perform
a validation on the mode name specified in the BIND image. Because SNASVCMG
sessions have to be established for CNOS operation before any other PTNR-MODEs can
start initiating sessions, the first unsolicited BIND request ought to come from the
SNASVCMG of the remote LU. Therefore, if the mode name specified in the BIND
image is not “SNASVCMG”, the BIND request will be rejected with a sense data
indicating session limit exceeded (%H’08050000’). If the mode name matches
“SNASVCMG”, the following dynamic object will be automatically added to the local
LU:
PTNR-LU
Object name = $<apc-process>.<local-LU>.“PLU-name”?
SNAName = “fully qualified PLU name”
Peripheral-Node = YES
Parallel-Session-LU = YES
