1. We have a VGA CRT monitor connected to the serial port of a KVM switch. And another serial cable from the switch to the server's display's adapter serial port.
2. It has worked previously.
3. At the moment we do not know what has changed as today my colleague looked at the display and saw that it was not responding. Other colleagues confirm that they were not able to connect to the machine few days ago but we were not informed until today.
4. How do I check the port setting?
5. We have not tried that and do not know how. How do we do that?
The machine we are using is a IBM eServer
I believe what you are looking at is not a serial port but a VGA connection on a graphics adapter! How many pins does the socket have? If it is 15 then it is a VGA adapter. If it is a VGA adapter there is no connection speed as it is not a serial port. This maybe on board but I cnnot tell as I do not know what the machine type is!
Saying it is an IBM eServer does not help very much. Is it a desktop (43p), tower system (F series I cannot remember the Power4 type numbers). The serial port is a 9 pin D type connector.
Actually I just thought the 43p series and the F series were not power4. Is this in fact a rack system?
more questions to go with the others has this ever been connected to a HMC and did you do any upgrades to the system? Is this a P570
Also do you have maintenance support for this HW from IBM.
Did somebody make a change to the inittab like try and comment out a line and used a # instead of a : some of the older system really did not like that to happen.
And as stated the code is c32 A directly attached display (HFT) was selected. The normal code is a 0C33 on machines I have worked on.
c33 A TTY terminal attached to serial ports S1 or S2 was selected.
So you need to boot to a maintenance shell. But if wrong display settings that won't help. Does it have HMC ports?
So a console fis procedure is as follows (if you can get the system viewable)
Code:
Instructions follow
NOTE: Your device names returned may be different than shown below.
Please substitute your device names.
1) Log into your system over telnet, ssh, modem, or serial connection. Do not use the console.
2) Redirect console messages (from a telnet or other remote session)# touch /tmp/console
# swcons /tmp/console
3) Disable getty temporarily.If you dont do this, you might not be able to remove the vty or vsa device.# vi /etc/inittab
change:
cons:0123456789:respawn:/usr/sbin/getty /dev/console
to:
cons:0123456789:off:/usr/sbin/getty /dev/console
3.5) Reprocess the inittab file
# telinit q4) Check your existing console entry, adapters and devices:# lscons (used only to see current setting)/dev/vty0# lsdev -C | grep savsa0 availablevsa1 definedvsa2 definedORsa0 available# lsdev -Cc ttyvty0 availablevty1 definedvty2 definedtty0 available5) Remove all the devices, adapters, and syscons entries from ODM.# odmdelete -q name=vsa0 -o CuDv
0518-307 odmdelete: 1 objects deleted.# odmdelete -q name=vsa1 -o CuDv
0518-307 odmdelete: 1 objects deleted.# odmdelete -q name=vsa2 -o CuDv
0518-307 odmdelete: 1 objects deleted.# odmdelete -q name=sa0 -o CuDv
0518-307 odmdelete: 1 objects deleted.6) Remove all vty's or the tty for your console# odmdelete -q name=vty0 -o CuDv
0518-307 odmdelete: 1 objects deleted.# odmdelete -q name=vty1 -o CuDv
0518-307 odmdelete: 1 objects deleted.# odmdelete -q name=vty2 -o CuDv
0518-307 odmdelete: 1 objects deleted.# odmdelete -q name=tty0 -o CuDv
0518-307 odmdelete: 1 objects deleted.7) Very important. Remove the syscons entry from ODM.# odmdelete -q attribute=syscons -o CuAt
0518-307 odmdelete: 1 objects deleted.
8) Run the bosboot command and save ODM changes withsavebase.# bosboot -ad /dev/ipldevice
# sync# savebase
9) RebootAt boot, the configuration manager (cfgmgr) will reconfigure vsa0 and vty0 (or tty) and prompt you to assign the console - this, since "syscons" is no longer set.
TROUBLESHOOT
If you are unable to get a login prompt after the above steps
and you still have a login over network via telnet or ssh, do
the following:
1) On command line run
# kdb
At the (0)> prompt type in "f 1" and enter
On the second line of the output, it should have a number
something like [0006fB48] et_wait+#######
et_wait is normal operation for the console - nothing is
holding the port from being opened successfully. If it
is anything else, the system may be blocked from
spawning a getty to your console due to a program
or application error in the /etc/inittab file.
These applications are often started in the "wait"
mode where the system will start them and wait
for them to return/complete before continuing (even
though the system boots OK).
2) If you still have problems with console, try adding
"clocal" to the stty attributes for runtime and attibutes
for login (it must be set in both).
you may have to follow the above procedure to
edit inittab and swcons so you can access/change
the device.
I tried to boot the machine using the AIX installation disc (I tried with 3 different sets of cds) but still the same thing. The machine failed to boot. But now, the LED shows 0c31 instead of 0c32.
Ok there is a question of what type of system this is. Need more than a e-server. Get the machine type from the label on the machine where the ser# is. so like 9115-505 or 9110-51A, 7047-185
something like that.
Also was this machine ever on a HMC. This is important because once attached to a HMC the system will always look for it.
So not being able to get the CD's or DVD to boot is saying that the SMS is set or you have failed HW. So is this system on maintenance where you can call IBM for support and a hardware replace if needed?
if you have a display as long as you are in sms menu, try to select the correct console ... than try the whole thing again. Usually it gets dark when you see the welcome display because there is no console / tty defined.
BTW - if its power4 I would guess its rather a 650/670 than a p5**
@aix_guy: the machine type is 7029-6e3. This machine is not and was never attached to a HMC.
@zxmaus: I went into SMS mode to select the console. Manage to do that by pressing "3". After that it started to boot again and automatically went back into SMS mode. But few days back when I selected the console, right after that it went back to the main SMS menu. The only thing change I did to the machine was unplug the network cable.
Power server up runs through diagnostics.
Goes to the boot section and then the bit where the cursor is spinning and thats it. Hangs completely.
Any ideas? (10 Replies)
