Configuring the System
Through SCF
In the previous subsection, SNAXUTL modified the SET table source file and SET table
object file to include a record for ESS1. In configuring the system, the SETTAB
attribute of the SCF ALTER SUBSYS $SSCP command must be specified so that LUNS
will use the modified version of the SET table and be aware of ESS1:
ALTER SUBSYS $SSCP,SETTAB $SYSTEM.SYS01.SNXSET
The ADD APPL command is used to assign subdevice names to the Tandem Creator
process, the TACL application, and SNAXUTL on \SYS1. The TACL process (#TACL)
is associated with the Tandem Creator process through the CREATOR attribute; the
APPLFILE attribute is also specified so that the Creator process can locate the object
file of the TACL.
ADD APPL $SSCP.#CREATE, APPLTYPE LUNSCRE, &
PASSWORD "SYZYGY "
ADD APPL $SSCP.#TACL, APPLTYPE LUNSAPPL, &
APPLFILE $SYSTEM.SYSTEM.TACL, &
CREATOR #CREATE
ADD APPL $SSCP.#SNAXUTL, APPLTYPE LUNSAPPL, &
PASSWORD "SNAXUTL "
Note that the Creator process is given the password “SYZYGY ” and SNAXUTL the
password “SNAXUTL ”. Remember that the password must be right-filled with
blank spaces, up to its total of eight characters.
Next, the gateway passthrough logical units are configured. The ADD LINE
command is used to define the gateway line ($G1). Then the ADD PU command is
used to define the gateway physical unit (PU1). Finally, the ADD LU command is
used to define the two gateway LUs (LU1 and LU2):
ADD LINE $G1, STATION SECONDARY
ADD PU $G1.#PU1, TYPE (13,2),RECSIZE 265,MAXLUS 2, &
MAXPTS 2, ADDRESS %HC1
ADD LU $G1.#LU1, TYPE (14,0),PUNAME #PU1,RECSIZE 1024, &
PROTOCOL SNALU,PASSTHRU ON,ADDRESS 2
ADD LU $G1.#LU2, TYPE (14,0),PUNAME #PU1,RECSIZE 1024, &
PROTOCOL SNALU,PASSTHRU ON,ADDRESS 3
Then the primary line ($P2) and its attached PU and LUs are configured. When the
two terminal LUs (LU3 and LU4) are configured, PROTOCOL is specified as ITI.
PROTOCOL is a required SCF attribute for any LU. Note, however, that this protocol
specified through SCF can be overridden by the protocols specified in the ESS table
logon records.
