MP Console not responding

[Jayan Nair]

Hi,

I have HP Itanium rx2620 with OS 11.23.

I can not use console display from the MP. It looks like session is hung.
I have attached screen shot of MP>co

I can open a session using KVM switch, but there i am getting

"X-Server cannot be started on display. For details look in the file, Dt login.errorLoffile( default:/var/dt/Xerrors)
**********************************************************

Suspending Desktop login
Desktop login will resume shortely after your logout."

The MP menu is functioning fine.
I have tried ctr L and ctr z but no response at MP console

Thanks
Jayan

Hi,

Use telnet to MP or LAN ip of server, if you are getting success then good.
Otherwiase you have to restart Hard Reboot.

Hi Gokul Thanks for the replay

I am not able to assign MP ip so i cant telnet to MP.
Telnet is disabled so I can't login to LAN.
I have hard rebooted also, but same status.
Have attached MP LAN status

Your server is up right now or not. If yes and MP console is not working you may need to take the reboot of the server.

And if your server is down or got hand in between booting process then go to MP> CM> RS. Reset the partition and check.

If no luck after this, register an hardware case with HP.

Thanks

Hi,

From the output of lc at the CM prompt - it shows DHCP enabled.
If you want to give static ip address, subnet mask and default gateway to your MP console then can you try disabling the DHCP and then see if it allows you to assign an ip address.
Please check with your Network admin for the details of the ip,subnetmask and default gateway.

Thanks Ninad,
I Assigned Mp IP.
But not able to connect MP by telnet.

Hi Jayan,

Let us first try to understand the problem.
Please confirm on the below points
1. Your server is up and running - so there is no problem on that front.
2. You want to be able to telnet the MP console and this is what you are not able to do.

Is there any other problem that we are missing out ?

You not being able to telnet to MP console IP address - there could be several reasons.
First let us understand from where you are trying to telnet.
Is the machine from which you are trying to telnet on the same subnet as the MP console IP address ?
If yes
Does telnet to some other machine work ?
Is telnet disabled ?
If no - (machine from which you are issuing the telnet tp MP console, and the MP console IP address are not in same subnet)
Is the subnet mask and default gateway on the MP console and the machine correctly configured ?

Are you able to ping the MP console IP address from your machine ?

Ninad

Have you assigned the subnet and gateway also?

Are you able to telnet server primary main IP?

Thanks

Hi
subnet, g/w is ok
But cann't telnet MP IP
ssh to LAN IP

[Aneesh Mohan]

Hi Jayan,

I suspect the display output configuration for your system console is in VGA port,if you want to acces HPUX through the MP console using the enabled protocol like ssh/telnet then it should be in serial port.

You may need to re-define the devices that display output from the system console.

Please have the following link ,it will explain you clearly.

Hi
***subnet, g/w is ok
But cann't telnet MP IP
ssh to LAN IP***

This mean you are able to telnet ip.
Ok
Now you want to Display on monitor. Yes you are not getting.
Due to illegal shutdown this happen.

From telnet

#cd /sbin/init.d
# ./dtlogin.rc start

Now you restart your machine,
you will get normal bootup not Text mode.

If you lan IP are ok. Otherwise you will not get Display.

ifconfig lan0 up (if not working lan0)

For ip assigning...

#ifconfig lan0 192.168.1.X(or you machine ip) netmask 255.255.255.0(subnetmask)

Hi,

Please go thru the document
HP Integrity and HP 9000: iLO MP Operations Guide for rx2620
http://docs.hp.com/en/5991-6006/index.html

I assume you have connected the MP console lan cable to your LAN switch correctly and the VLAN configuration if any on the LAN swicth is correct.

One thing I did not understand is you said that telnet is disabled, whereas you also said that you are able to telnet to console of other servers.

Hi,

From the link I provided to you, it seems that you need the iLO MP Advanced Pack License to be able to use ssh.

Thus if as you say telnet is disabled, and you have to use ssh, then you would need this license.

But as I have put, I still did not understand where is telnet disabled ? if you are able to telnet other consoles and server ip addresses.

Ninad

[Jayan Nair]

Hi Anish,
Could you please be more specific how to do it.

Ninand
telnet is enabled only for remote MP login.
For LAN ip telnet is disabled.

Thanks
Jayan

Hi jayan,

1) Acees the MP console window and keep it open (as u said u can acces through ssh or also u can direct connect to the serial port with the laptop)

2) Reboot the server ( from normal telnet window to the server )
#shutdown -ry 0

3)While rebooting interrupt autoboot using the MP console.

4) Using the Boot Menu ,select Console configuration

5) Use this option to define the devices that display output from the system console. This list normally includes the VGA monitor and a serial port for directing output to a terminal emulation package.

6) Select ILO MP Serial Console
Acpi(HWP0002,700)/Pci(1|0)/Uart(9600 N81)/VenMsg(Vt100+)

7) When changing serial devices, changes must be made to Output, Input, and Error menus for proper operation.
8) Save and reset the system

You cant telnet to MP to access the co since your output already set to VGA. So follow Aneesh Mohan steps, you should be able to access through serial cable.

As for X-Server error, try to check setting under /etc/dt/config/Xserver and remove '#' if exist. Then go to /sbin/init.d, stop and start the dtlogin, ./dtlogin.rc stop and ./dtlogin.rc start. If still fail, try to check your dns and hostname, make sure there are correct.
