Architectural base

The data structures defined by the architecture are:

The PARTNER_LU structure describes a partner LU. This information includes the partner LU's names, local LU name, network-qualified LU name, and uninterpreted LU name. It also includes the set of the LU's optional capabilities such as parallel sessions. The PARTNER_LU structure also contains a list of mode descriptions. The list of mode descriptions has one entry for each mode name that is defined for the particular partner LU name.
The MODE structure describes a logon mode that can be used to establish sessions with a partner LU. This structure contains the session parameters that characterize this mode, such as maximum RU size. It also includes the set of optional functions that are supported by the partner LU on a mode basis.
The MODE structure contains several session limit fields. These fields limit the total number of sessions and the number of contention-winner and contention-loser sessions that this LU can have with the partner LU and mode name represented by the MODE structure.
