MSA and HP-UX console

shashi kanth — Fri, 18 Sep 2009 11:03:10 GMT

I have connected MSA to one of my HP-UX box through serial cable.

From HP-UX, what is the command and it's syntax to connect to the MSA console ?

I have gone through "cu", but i am getting the error "Connect failed: Requested device/system name not known"

I guess the tty name may not be correct.

how to check the which tty file associated with that serial console connected to MSA ?

ioscan shows many tty words, i tried with all tty's but still i am getting the same error.

#ioscan -fn | grep -i tty
tty 0 0/4/1/0 asio0 CLAIMED INTERFACE PCI SimpleComm (103c1290)
/dev/diag/mux0 /dev/mux0 /dev/tty0p0
tty 1 0/4/1/1 asio0 CLAIMED INTERFACE PCI Serial (103c1048)
/dev/GSPdiag1 /dev/diag/mux1 /dev/mux1 /dev/tty1p0 /dev/tty1p2 /dev/tty1p4
tty 2 250/1 asio0 CLAIMED INTERFACE Built-in RS232C
/dev/diag/mux2 /dev/mux2 /dev/tty2p0

the command what i am using is ...

#cu -l /dev/tty2p0 -s 19200
Connect failed: Requested device/system name not known

What server and what MSA do you have?

There are many different models for each ...

tty2p0 is the device for the build-in port (COM1), where did you connect the cable?

I have connected to the MSA first controller.

From the server back side "console" port to the front port of MSA first controller.

Just to verify - connect the cable to the port on the chassis between TOC button and USB ports.

Another question - do you have a MP installed?

If not, this port is the system console and you cannot connect other devices.

IIRC you need an appropriate entry in /usr/lib/uucp/Devices

shashi kanth — Fri, 18 Sep 2009 11:41:54 GMT

yes, its connected between TOC and USB

Re: MSA and HP-UX console

shashi kanth — Fri, 18 Sep 2009 11:43:36 GMT

Try to add this line to the Devices file

Direct tty0p2 - 19200 direct

then use cu -l ...

Re: MSA and HP-UX console

shashi kanth — Fri, 18 Sep 2009 11:55:23 GMT

I added the line "Direct tty0p2 - 19200 direct" to /usr/lib/uucp/Devices.

#cu -l /dev/tty0p2
Connect failed: line problem

#cu -l /dev/tty0p2 -s 19200
Connect failed: line problem

is the tty0p2 right device ?

Thank you Torsen. I got it.

I added "Direct tty2p0 - 19200 direct"

then with "cu", i am able to connect.

Thanks.

Great!

I did not work with "cu" for so many years - good to hear this is working.
