I do have p520 with two integrated serial port. As per IBM document integrated serial port is for only minimum use so i installed addtional pci-x 8 port async serial adapter in the same box. And also add tty0 using command smitty tty.

System shows vty0 and vty1 for integrated serial adapter and tty0 for 8port async adapter. (i configured only tty0)

problem:
I tried a third party tools called portchk to check the port status and gave following command to do it.

#portchk /dev/tty0 5
after giving this command got below error message after few seconds
DEVICE OPEN ERROR

and i tried same for vty0
#portchk /dev/vty0 5
below message appeared
PORT OPEN SUCCESSFULLY
ioctl (GET) successful
ioctl (SET) successful

But, I need tty0 not vty0

Please any one can tell me what may be the problem in tty0

and also is there any aix command to check the status of serial port.

Hello,

This may not be what you are looking for, but:

There is information in the PowerHA/HACMP manuals about testing a serial network between two
AIX nodes.

Unfortunately it does not copy and paste well. :)

Search for "stty" in the HACMP installation guide.

The pub number for the 5.5 version is: SC23-5209-02

Which should be available from here:
http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=/com.ibm.cluster.hacmp.doc/hacmpbooks.html

Hope this helps,
Casey
