NOF API Verbs (ACTIVATE_SESSION to OPEN_FILE)
ACTIVATE_SESSION
Chapter 3 117
ACTIVATE_SESSION
The ACTIVATE_SESSION verb requests SNAplus2 to activate a session
between the local LU and a specified partner LU, using a specified mode.
You must issue an INITIALIZE_SESSION_LIMIT verb before issuing an
ACTIVATE_SESSION verb, unless cnos_permitted is set to AP_YES.
This verb must be issued to a running node.

lu_name
LU name of the local LU, as defined to SNAplus2. This
is an 8-byte type-A EBCDIC string,padded on the right

indicate that the LU is defined by its LU alias instead
of its LU name, set this parameter to 8 binary zeros.
