ADD DEVICE Command
IOPOBJECT $SYSTEM.SYSnn.LHOBJ
is the name of the object file containing the executable object code for an Expand
line-handler process. This value must be $SYSTEM.SYSnn.LHOBJ.
PROFILE profile_name
is the name of the profile you created for the path in Step 1: Create a Profile for the
Path-Logical Device.
CPU cpunumber
is the processor number where the path-logical device will normally execute.
ALTCPU altcpunumber
is the processor number where the backup path-logical device will normally
execute.
TYPE (63,1)
is the device type and subtype for the path-logical device. The device type is
always 63 for Expand line-handler processes. The subtype is always 1 for path-
logical devices.
RSIZE 0
The RSIZE value must be set to 0.
NEXTSYS sys_number
is a required modifier that specifies the number (from 0 through 254) of the system
connected to the other end of the path. If you do not specify NEXTSYS, this
modifier defaults to an invalid value (255) and an operator message occurs during
the initialization of the path-logical device. The path will not be operational until you
alter NEXTSYS to a valid value using either the WAN subsystem SCF ALTER
DEVICE command or the Expand subsystem SCF ALTER PATH command.
modifier_keyword
is the name of an optional modifier in profile_name. modifier_keyword is
added to the device record for this path-logical device.
Modifier names in the PEXPPATH profile are listed in PEXPPATH Modifiers on
page 14-15.
Note. If the multi-line path will be part of a multi-CPU path, you must specify the
SUPERPATH_ON and L4EXTPACKETS_ON modifiers when you configure the path-logical
device. The L4CONGCTRL_ON modifier is recommended for multi-CPU paths.
