Purpose
VARY HANGUP is used to take down a switched subarea connection or a switched connection to a type 1,2, or 2.1 device. This allows the connection to be terminated when it is no longer necessary.
- VARY HANGUP terminates only the switched connection; it does not deactivate the line or the physical unit.
- If the existing connection is for Enterprise Extender and DWINOP=YES
is specified on the switched PU definition on the remote host, the
remote host will attempt to redial the partner on this host when the
VARY HANGUP command is issued on this host. If the VARY HANGUP command
successfully places the switched PU in connectable state, then the
dial-in from the remote host will be accepted and the connection will
be reestablished.
Issuing VARY INACT for the switched PU will prevent this from occurring unless VARY ACT is then issued for the switched PU before either all dial retries by the remote host have completed or VARY INACT is issued for the switched PU on the remote host to terminate the redial attempts. See the descriptions of the DWINOP, REDIAL, and REDDELAY operands in z/OS Communications Server: SNA Resource Definition Reference for details.
In addition, coding CALL=OUT on the Enterprise Extender PATH statement under the PU, or ANSWER=OFF on the GROUP statement in the XCA major node to which the PATH statement applies, will prevent inbound dial attempts from being successfully directed to this PU.
