DTS Shutdown

The DTS shutdown capability is provided by the DTCCNTRL command. It allows you to bring down the entire DTS subsystem and includes the release of all TIO-related system resources. DTCCNTRL requires that you have a minimum of System Manager (SM) capability. This operation can only be done from the system console.

When combined with the DTS restart capability discussed in the next section, you can resolve errors that may arise during Datacomm Configurator (DCC) start-up without rebooting the HP 3000 host. If you see DCC error messages, first fix any problems that caused the DCC startup error and then run DTCCNTRL to shut down and restart DTS. Refer to Appendix D for more information on DCC errors.

	NOTE: Issuing the DTCCNTRL command to perform a DTS shutdown will result in the deletion of the entire DTS/TIO subsystem from the system. No TIO users can use the system while it is shut down.

When DTS shutdown is invoked, all devices that are configured by the DTS subsystem are scanned and DOWNed. If any device is found that is logged on, spooled or owned by any process then the shutdown will not continue and all DOWNed devices are returned to the UP state. No active sessions or owned devices are affected. If no owned or in use devices are found then the shutdown will proceed to delete all DTS ldevs and release all DTS resources.

If desired DTS shutdown can be invoked with the "forced" option. If the "forced" options is specified, then any devices that are logged on, spooled or owned by any process will be reset and the sessions aborted. The "forced" option is specified on the command line when DTCCNTRL is invoked. See the next section for the syntax used to invoke DTS shutdown.

Performing a DTS Shutdown

To perform a DTS shutdown, type the DTCCNTRL command at the CI prompt either without specifying the desired shutdown operation or by specifying it using the syntax outlined below:

• DTS shutdown operation not specified:

  :DTCCNTRL
  0	exit
  1	dynamically implement DTS changes made in NMMGR
  2	view status of last DTS dynamic configuration
  3	automatically add a new DTC
  4	shutdown DTS subsystem
  5	restart DTS subsystem
  6	manage/dynamically configure host-based x.25
  7	help
  For help on these topics, select 7 at the prompt below.
  Select one of the numbers above corresponding to the desired operation: 4

• DTS shutdown operation specified:

  :DTCCNTRL func=shutdown

  or to invoke the "forced" option:

  :DTCCNTRL func=shutdown, forced=y

	CAUTION: When the "forced" option is invoked, then all sessions logged on to TIO devices will be aborted and all spooled TIO printers will be stopped.

	NOTE: To dynamically configure DTS changes, refer to the "Dynamic Configuration" section earlier in this chapter. To automatically add/configure a host-based managed DTC to DTS without needing to specify detailed configuration information such as DTC cards/boards and ldevs, refer to Chapter 3 “Automatic Configuration of DTCs” To manage/dynamically configure host-based X.25 links, refer to the Configuring and Managing Host-Based X.25 Links manual.
