kernel para change (mxssize,mxssize_64bit) INIT: Command is respawning

Akif_1 — Tue, 07 Jul 2009 10:15:10 GMT

Hi All,

HP-UX
OS:11.11
hp Workstation C3700.

After changing kernel parameters of mxssize and mxssize_64bit reboot with new kernel unable get a login screen. below are the errors.

INIT: Command is respawning too rapidly.
Will try again in 5 minutes.
Check for possible errors.
id:cons "/usr/sbin/getty console console # system console"

NIT: Command is respawning too rapidly.
Will try again in 5 minutes.
Check for possible errors.
id:cons "/usr/sam/lbin/stand # system mgmt daemon"

NIT: Command is respawning too rapidly.
Will try again in 5 minutes.
Check for possible errors.
id.ems4:/etc/opt/resmon/lbin/p_client.

Note; unable to access through single user mode and serial (hyper terminal).

Need expert advice to solve this issue.

Rgds,

Shalom,

kmtune -l | grep max

I think you may have gotten the names wrong above. Changing these parameters should not have caused the problem, even if you exceeded maximum value.

If you meant maxtsiz and maxtsiz_64 the paramters are dynamic and did not require a reboot.

Hi Akif,

Did you tried to reboot with alternate disk or do you have ignite backup.

Also try to boot from pervious kernel

Ref the Link

Hi Steven,

Parameters are correct which i describe above (maxssiz & maxssiz_64bit), Iam crippled unable to get any prompt to shoot the commands.

As serial cable also doesnt work not single user mode working........

This are the STATIC parameters and a new kernel booted if i could login i try to use old kernerl for rebooting system in a normal state........

Hi

Try to boot from your kernel backup or from the alternate disk and see server is booting or not???

Hi,

There is no alternative disk only OS media is available and its not auto booting.

I plan to use recover option with OS media but failed due to cd not booting after system reboot.

Hi Akif,

I have seen this problem several times.. even in SCO UNIX. I am sorry to say cant find a proper solution.
you may Check your inittab file.

This is just a suggestion.

Today i try to do fresh installation of latest OS HP-UX 11i v3 and CDROM autoboot is not working and iam unable to progress further even with new installation.

Are the disk failed or any relevant issue with firmware.as iam unable to connect even with serial cable - hyperterminal.....

>After changing kernel parameters of maxssiz and maxssiz_64bit reboot with new kernel unable get a login screen.

What values did you use? Making maxssiz too large could make your system unusable.

>if I could login I try to use old kernel for rebooting system in a normal state

Why not? You interact with the PDC, as Jitesh said.

> Today I try to do fresh installation of latest OS HP-UX 11i v3

Neither 11.23 nor 11.31 is supported on your workstation.

>SEP: Changing these parameters should not have caused the problem

Sure it might. Every byte you increase maxssiz, you decrease maxdsiz, if the total is > 1 Gb.

Hi Dennis,

Yes i agree that i change kernel parameter with high values and after that only this problem started.

Now unable to get a login prompt or MP connectivity nor i do have any ignite backup.

I appreciate your valuable output to reach my destination.......

Can i use Floppy drive as any emergency boot if YES , Kindly send me a path to download and prepare emergency disk for booting purpose

>I agree that I change kernel parameter with high values and after that only this problem started.

What were the values so that everyone knows not to do this? You have to set them near 1 Gb.

>Can I use Floppy drive as any emergency boot?

I wouldn't expect a floppy to be in a HP-UX workstation?
Any reason you don't have a backup kernel?

>I plan to use recover option with OS media but failed due to cd not booting after system reboot.

Why? If that fails, I'm not sure a floppy would work, especially since the floppy is just too small now days.

Do you have another HP-UX system that you could create ignite?

If you have a support contract, the Response Center may help.

>The value of kernel parameter is 2.5GB

Yes, that's way too big (10 X) for maxssiz.

>backup of kernel is there but I am unable to login from MP and boot.

If you can't get to the MP, how are you booting at all? You can't get to the ISL prompt?

Re: kernel para change (mxssize,mxssize_64bit) INIT: Command is respawning

Akif_1 — Sun, 12 Jul 2009 07:26:01 GMT

Yeah after boot with vmunix system message "System is ready" and then above INIT error started.

But i tried to connect through hyper terminal with serial cable i am unable to get MP console.

Neither i can ping nor login root or MP.

Any other solution will be appreciated.

>after boot with vmunix system message "System is ready"

You need to interrupt the boot sequence so you can tell it to boot the previous kernel. You should see some message saying you have 10 seconds to interrupt the boot.

>Bottom display shows REMOTE MODE / DISPLAY FUNCTIONS / AUTO LF

You need to make sure these are back the way they were. There should at least be a "*" in Remote Mode.

See these man entries:
http://docs.hp.com/en/B2355-60130/boot.1M.html
http://docs.hp.com/en/B2355-60130/isl.1M.html

It's a command like:
ISL> hpux boot /stand/vumix.prev

>Yes "*" is on REMOTE MODE

Is there any other to connect workstation like LAN card .......MP console is there but dont know the IP's.

Check man pages it will not valuable untill system respond to MP or ISL prompt.
