Ibm System P5 Serial Connection Distance
As part of my upgrade from AIX 5.2 to 5.3, I have upgraded the firmware on my P51A dev server. I still need to upgrade the ethernet adapter firmware before I go to 5.3 though, but I was unable to get a console connection up between my notebook and P5 server?

I do not have an HMC. I was able to make a connection with a serial-serial cable to my IBM SAN switches, but not to any of my P5 servers. I am making use of ZOC Terminal software and have tried a BAUD rate or 9600 with 8N1, as this is what a tech from IBM UK suggested, but I am still unable to connect.

I have tried Hyperterminal too, but this does not work either. My console is assigned to /dev/tty0 and it is enabled and the settings of tty0 look like this: TTY tty0 TTY type tty TTY interface vcon Description Asynchronous Terminal Status Available Location Parent adapter sa0 PORT number 0 + Enable LOGIN disable + TIME before advancing to next port setting 0 +# TERMINAL type ibm3151 FLOW CONTROL to be used xon + STTY attributes for RUN time hupcl,cread,brkint,icrnl,opost,tab3,onlcr,isig,icanon,echo,ec + STTY attributes for LOGIN hupcl,cread,echoe,cs8 Sorry for the poor formatting. I have tried setting enable login to enable, but this dd not make any difference.
Any suggestions would be appreciated, as the 5.3 upgrade is on hold till I get a console up-and-running. Thanks kat000003 RE: Unable to create console connection between PC and P5. I know IBM servers are pretty choosy about handshake lines on serial ports, so you might want to try another type of cable. I used to make my own cable with following jumpered lines: for 25pin D connector: 1 -shield- 1 2 - 2 possibly 3 depends on connected device 3 - 3 2 7 - 7 4 - /- 4 5 -/ - 5 6 - /- 6 8 -+ +- 8 20 -/ - 20 for 9pin D connector: 3 - 3 or switch 3 and 2 2 - 2 5 - 5 7 - /- 7 8 -/ - 8 6 - /- 6 1 -+ +- 1 4 -/ - 4 HTH, p5wizard RE: Unable to create console connection between PC and P5 (TechnicalUser). Do you have an async card in this system that you are using to connect the console? Your print out show adapter sa0, which signifies such.
If not, and you are using one of the vty ports (S1 S2) on the back of the system, you should assign the console to that vty port (smit), and not to a tty. Tyically you cannot create a tty device on a vty port.
Vty ports have a default baud rate of 19,200 (8 1 n). This cannot be changed using smit, you must use ASM to do it. Although it appears that smit is changing it, there is no affect on the actual settings. Also, since you indicated you upgraded the firware on this system, I assume the console connection must have worked previously. I have done many firmware upgrades on P5 systems and have never seen this happen. If you put the new firmware on only the temporary side, go back and boot from the old firmware (permanent) and see what happens.
