Dynamic Conﬁguration and DTS Shutdown/Restart

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.
