ioscan for tty

[Raj_Ranjan]

Hi,
Can someone please explain me the output of the command in attached file.

If anyone can provide me with some document regarding serial port in hpux.

Thanks

These are several serial ports.

#ioscan -funC tty
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
tty 1 1/0/0/0/0 func0 CLAIMED INTERFACE PCI BaseSystem (103c128d)
tty 0 1/0/0/0/1 asio0 CLAIMED INTERFACE PCI Serial (103c1048)
/dev/GSPdiag1 /dev/mux0 /dev/tty0p1
/dev/diag/mux0 /dev/tty0p0 /dev/tty0p2



Without knowing your server model I cannot tell you much more.

What do you want to do?

[Raj_Ranjan]

server model is L2000. As these servers are in remote location. I want to know what are connected to serial ports and which ports are vacant...

[Torsten.]

Would you run "model" on this system to confirm this?

Somehow this does IMHO not match an L-class.

[Raj_Ranjan]

# model
9000/800/L2000-44
root@demo [/etc]

[Torsten.]

I would expect this for a L-class (note the hardware path - depends on GSP model and firmware):

tty 0 0/0/4/0 asio0 CLAIMED INTERFACE PCI Se
rial (103c1048)
/dev/GSPdiag1 /dev/tty0p0
/dev/diag/mux0 /dev/tty0p1
/dev/mux0 /dev/tty0p2

** OR **

tty 0 0/0/4/1 asio0 CLAIMED INTERFACE PCI Ser
ial (103c1048)
/dev/GSPdiag1 /dev/tty0p0
/dev/diag/mux0 /dev/tty0p1
/dev/mux0 /dev/tty0p2


Anyway, 3 serial ports come out of the GSP:

console, UPS connector, modem connector - these are the p0,p1 and p2 ports you can see.

[Torsten. · Accepted solution]

Are you really sure you took this ioscan on this L2000?
This looks to me more like a rp7410 or something similar.

Anyway, for what reason you need "vacant" ports?

[Raj_Ranjan]

Very sorry, Its RP7410. You are correct. But one thing how you can say that so confidently just by seeing the ioscan.

output for rp7410

# ioscan -funC tty
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
tty 1 1/0/0/0/0 func0 CLAIMED INTERFACE PCI BaseSystem (103c128d)
tty 0 1/0/0/0/1 asio0 CLAIMED INTERFACE PCI Serial (103c1048)
/dev/GSPdiag1 /dev/mux0 /dev/tty0p1
/dev/diag/mux0 /dev/tty0p0 /dev/tty0p2


and for L2000

# ioscan -funC tty
Class I H/W Path Driver S/W State H/W Type Description
==================================================================
tty 0 0/0/4/0 asio0 CLAIMED INTERFACE PCI Serial (103c1048)
/dev/GSPdiag1 /dev/mux0 /dev/tty0p1
/dev/diag/mux0 /dev/tty0p0 /dev/tty0p2
tty 1 0/0/5/0 asio0 CLAIMED INTERFACE PCI Serial (103c1048)
/dev/GSPdiag2 /dev/mux1
/dev/diag/mux1 /dev/tty1p1


Thanks,

[Torsten.]

This is just experience ... I like to read ioscan's.

[Raj_Ranjan]

can you please share some with me.
