Dynamic Configuration and DTS Shutdown/Restart

DTS Shutdown

Chapter 4

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 e3000 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 E, “Error Messages,” 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
