Acceptable Formats for User Defined Connection Requests
In addition to using predefined nickname resources, when a port is configured to allow
the user to define the requested resource the LUNAME field of the client must use one of
the acceptable formats for making that request. Among the accepted formats are:
Pool_Name – Use one of the pool names that have been defined. Pool names are case
sensitive. LUs from the pool will be allocated based on the allocation algorithm used by
the CNA-8000. Only sessions from the requested pool will be allocated. If all sessions
associated with the pool are in use, a message indicated that the resource is currently
unavailable.
Host_Name – Use one of the configured Host Circuit names that have been configured.
Any available LU defined for that Host Circuit may be given to the requesting client.
Host_Name,LU_Number – Only the specified LU associated with the specified Host
Circuit will be allocated to the client. If the requested resource is already in use, a
message indicating that the resource is unavailable will be sent using an NVT datastream.
Host_Circuit_Number,LU_Number – In place of using a configured Host Circuit
name, the host circuit number may be used. Only the specified resource will be allocated
when requested and only if it is available. If the requested resource is already in use, a
message indicating that the resource is unavailable will be sent to the client using an
NVT datastream.
Note that if the option to ‘Restrict Connections to Active LUs’ is enabled and the
requested resource is not active, then a message will be sent to the client indicating that
the resource is not available.
