DTC configuration

[Alan Riggs]

In one of those lovely turns of a sysadmins day I have suddenly been given the urgent task of configuring an HP2345A 48-port DTC. The configuration must be driven from either a D or a K box running HP-UX 10.20. There is, of course, no documentation for the present configuration (configured from a PC on a different continent -- yes, I said continent) and I do not have physical access to the device.

Any hints, even so broad as to give me the name of the daemons/software required, will be greatly appreciated.

Hi Alan,
What you want to look at is ddfa (there should be a man page).

There should also be an /sbin/init.d/ddfa to start the services up

/etc/ddfa holds all the config files

dp - holds the IP <--> device files info
pcf - holds the communications setup info

Let me know if you need and example of these.

regards,
AG

Anthony, I have found /etc/dfa already. It seems to hold configuration information for the 9000 server to address the DTC connections. What I need, though, is the method to provide the DTC itself with configuration upon reset.

Does the ddfa handle both tasks?

Alan,
There is a HP-UX utility (#dtcconfig) that is used to configure a dtc and also each port on that dtc.
The only thing you REALLY need to know is how the physical dtc has been named.
I believe that #dtcdiag will give you that info if you know the IP address of the dtc.
Try the man page for dtcdiag (there are LOTS of things it does).
Good luck!

I think there are a few things you can look at

1. HP DTC Manager/UX (J2120B)
With the DTC host-based management, a simple terminal connected locally or
remotely to an HP 9000 system is used to manage DTCs. It provides a means to
configure DTCs in HP 9000 standalone or multi-system Telnet-TCP/IP environments.

2. DTC 16RX Manager (J2496B)
The DTC 16RX Manager is similar to the DTC Manager/UX, but manages only DTC
16RXs. It provides routable management and routable data path, HP 9000 and HP
3000/900 access, and back-to-back configuration.

3. PC running HP OpenView DTC Manager Software (D2355B)
Note: DTC Manager 14.3 requires OpenView DOS/Windows? version 7.2. Therefore,
you must either already have an OpenView product running on version 7.2 or
purchase OpenView Runtime version 7.2 (32048E). The HP OpenView (PC-based)
DTC Manager software provides an easy-to-use graphical user interface to
manage DTCs.

Hope this helps...

Thanks for the pointers.
