Itanium console woes

I have an Itanium box set up to use the serial port as the console. The console, however, does not respond to a control-b. This is my first time on an Itanium console, but I'd expect that there should be some way to -- at least -- break in and force a crash. Any insights? Anyone?

Re: Itanium console woes

Tell us the model you have.

cntl-B only works when connected to the MP (maintenance processor). There are a lot of ways to setup a console on Itanium.

Some of the serial ports are not MP ports. Most use the 3-way 'dongle' cable.

It's an rx1620. This particular machine has the db-25 three-way port and a LAN-console port. These ports respond to the ctrl-b and give me the MP menu. However, when I use serial-a as the console, ctrl-b does nothing.

"So use the MP." you say. Alas! Not all our itanium boxes have the LAN-console or the three-way db-25. Some just have the serial port.

Shalom,

It may be a problem with the hardware you are using as a console.

If available, its almost always better to use the LAN console. You can telnet into it from your desk and not spend fun time in the noisy computer room.

You can use procomm through the serial cable to get to the console and ctrl-b using a garden variety laptop with a usb to serial converter. Thats how we do it.

Re: Itanium console woes

Like Scot said already, key sequence will only work on a console port managed by MP ( Management Processor ). This key sequence is an interrupt which activates the MP Text Interface.

Serial port A is not controller by MP so you won't go anywhere after pressing key sequence.

Re: Itanium console woes

If you connect on the "console" port instead of the three-way db25 to db9 controller, you will interact directly with the BMC (baseboard management controller) which is much more limited than the MP. I think the MP was an option on the rx1620, if yours doesn't have one you'll have to live with the BMC.

IIRC there is a special control key on the BMC which will do the same as CTRL-B on an MP, but I don't remember exactly what it is, I never used it. Hand out points and some people might be willing to look it up for you.

Re: Itanium console woes

Using the 3-way dongle connected to the 25-pin serial port is the way to go.

If not all of your machines have them (all machines should ship with these cables), you will have to order some or configure the LAN console port.

Re: Itanium console woes

If memory serves me right the management processor is optional on certain models.
So if you have some Itaniums without the three way DB25 they're most likely ordered with the management processor.
