DEVICE= device-name
specifies the device name used by the unit. For an SNA link and an X.25 link, the
device name must be the name of a subdevice, in the form:
[ \ sys . ]$ device [ .# subdevice ]
No other unit on the same side of the link can specify the same device name or
share this device name.
For a process-to-process (PTP) link, the device name must be the name of the disk
file used as the mailbox, in the form:
[ \ sys . ][ $ volume . ][ subvolume . ] file-name
The mailbox file name can be on either the local or remote system. If the mailbox
file does not exist, it is created. The mailbox file is opened when the link is started.
A unit pair must specify the same mailbox file name. No other unit pair can
specify the same mailbox file name or share this mailbox.
MODE
specifies the role of the unit in the link.
PRIMARY
specifies the primary unit in an SNA or PTP link. The corresponding unit to a
primary unit must be secondary.
For an SNA link, the primary unit is the primary logical unit of the SNA
session.
For a PTP link, the primary unit is the unit that issues the first Guardian
OPEN procedure call.
SECONDARY
specifies the secondary unit in an SNA or PTP link. The corresponding unit to
a secondary unit must be primary.
For an SNA link, the secondary unit is the secondary logical unit of the SNA
session.
For a PTP link, the secondary unit is the unit that creates the mailbox file and
waits for the Guardian OPEN procedure call from the primary unit.
ACTIVE
specifies the active unit in an X.25 link and specifies that the unit is a switched
virtual circuit. The corresponding unit to an active unit must be passive.
