Configuring LUNS Passthrough

As mentioned earlier, SNA host applications may be configured as LUNS applications

(through ESS table entries) optionally. This type of configuration is called LUNS

passthrough.

Figure 5-3 on page 5-6 shows an example of LUNS passthrough. The normal

passthrough configuration is required. In addition, an ESS table and SET table are

required. The SNAXUTL configuration, shown alongside, defines an ESS table

(ESSTAB1) with various types of entries and adds it to a SET table. The SNAX/XF

SCF configuration defines the SET table to the subsystem.

Notes.

1. Secondary LINE objects must have STATION SECONDARY and APPLID (containing host

applications you want to access from the NonStop system)

2. Passthrough LU objects must have the following attributes:

PROTOCOL SNALU

PASSTHRU ON

ASSOCIATE (if associated or static passthrough required)

STATIC ON (if static passthrough required)

3. After configuring SNAX/XF, you must still configure the gateway lines, PUs, and LUs to

VTAM, NCP, and NPSI (X.25 lines) and activate these resources from VTAM. For further

information, see Section 4, SNAX/XF Secondary Lines

SNAX/XF and SNAX/APN.
