The ADD LINE, PU,

and LU Command

Attributes

When using SCF to configure lines, PUs, and LUs, you can specify several attributes in

an ADD command that directly affect LUNS processing.

AUTOLOGON Attribute The syntax for the AUTOLOGON attribute is as follows:

AUTOLOGON "

ess-table-entry-name

" is the name of a record in the ESS table that SNAX/XF

processes when an LU is started. This record can be a logon command, an order

command, or an ESS message. If the record entry contains a logon command, the LU

is logged on to the system in the way specified by the command. However, if the

record entry corresponds to an ESS message, the message is displayed at the terminal

when the LU is started. The record cannot be an INITSELF-RECEIVED request.

ADD LINE

When the AUTOLOGON attribute is specified by the line object, the value for "

ess-

table-entry-name

" serves as a default value for all LUs subordinate to the line,

with the following exception:

The default value is not propagated to those LUs that have an AUTOLOGON

value specified by the LU object.

ADD PU

When the AUTOLOGON attribute is specified by the PU object, "

ess-table-entry-

name

" serves as a default value for those LUs subordinated to that PU, with the

following exception:

The default value is not propagated from the PU to those LUs that have an

AUTOLOGON value specified by the LU object with an ADD LU command.

ADD LU

When the AUTOLOGON attribute is specified by the LU object, "

ess-table-entry-

name

" overrides the value specified by the AUTOLOGON attribute in the line and the

PU object.

Switched Floating LUs

The AUTOLOGON value is not propagated from the line, LU, or PU object to

switched floating LUs. For switched floating LUs, the AUTOLOGON value must be

specified with an ADD PU command (which propagates the value to the switched

floating LU), or with an ADD LU command.

Changing an LUs AUTOLOGON Value

The AUTOLOGON value for existing LUs can be changed to specify a different record

in the ESS table name with the ALTER LU command.
