The BIND Table
Introduction to LUNS

The BIND Table Before an LU-LU session can be established, the PLU and the SLU must agree on
“communication rules.” The PLU communicates these rules to the SLU by means of
session parameters that are sent to the SLU in a BIND request.
The SNAX/XF Utility (SNAXUTL) allows the user to build individual BIND images
and place them into BIND tables. Use the ADD LOGMODENT to create the BIND
table. Use the ADD SETLOG command to add a bind table record to the SET table.
When SNAXUTL builds the BIND table, it creates a source file and an object file. The
object file is used by SNAX/XF to retrieve the BIND image. The source file is a key-
sequenced file, and the object file is an unstructured file.
Use the SCF ADD or ALTER BINDENTRY command to associate BIND images to
LUs. When an application opens the LU, the BIND entry name specified with SCF is
used to retrieve the BIND image from the BIND table.
A BIND table name and/or BIND table entry can also be specified in an ESS table
entry.
What Tandem
Provides
With the SNAX/XF release, Tandem supplies:
A Tandem Creator process
Two starter ESS tables:
$SYSTEM.SNAX.SMLNERRS, an edit command file containing only system
messages and a Tandem logo as the ESS message 10
$SYSTEM.SNAX.ESSFILE, an edit command file containing various types of
command records and message records
A starter SET table with:
$SYSTEM.SNAX.SETFILE, a command file containing SNAXUTL commands
that creates a SET table and adds to it four ESS table records
$SYSTEM.SNAX.SNXSET, a table source file with four records; these records
contain entries identical to those that would be created by the SNAXUTL
commands in $SYSTEM.SNAX.SETFILE
$SYSTEM.SNAX.SNXSETO, a table object file corresponding to the table
source file in $SYSTEM.SNAX.SNXSET
