System won't boot after kernel parameter change

[Kuekuatsheu]

Thanks Don,

However, when we tried to mount /usr, the system returned that /usr is busy. Is there another way around this? Booted the vpar in LVM maintenance mode but the system would not boot also.

Do a "ls /stand" and note the directory names. Those are the configurations -- and you'd be looking for anything other than current, I would think. Assuming you find one, go back to "vparload -p -b /stand//vmunix" -- that should boot the alternate configuration with prior tunable values. At which point, you can kctune -c the other configuration to get back.

last_install would be a good one if it is there too.

[Kuekuatsheu]

We tried to boot from the last_install. Now, the kernel won't even boot in failsafe mode.

All with the same out-of-memory panic? (Which wouldn't make any sense unless last_install is the only real configuration... but that's not at all the default).

Console logs of the vPar booting from loading vmunix to the panic might help here.

Here's what the console shows:

HP-UX Boot Loader for IPF -- Revision 2.029

Error: kernel does not contain required vPars components.

[MON]
vPar "ANALYTICS" failed to load the kernel for either trying to boot an unsupported kernel in vPars environment or having incorrect vPars software installed on the boot device.
Error loading "ANALYTICS". Shutting down "ANALYTICS"...

[Don Morris_1]

Ah... ok.. so it swapped last_install into the current configuration, but last_install was installed as an nPar not a vPar (and there are missing kernel modules needed).

Do you still have the ls output of the available subdirectories under /stand? All we need to do is find one of your vPar configurations -- preferably not the one you were running, but if we must then you can get back to booting that in failsafe mode [one of the things Failsafe would have done is explicitly copy that configuration to a unique name it displayed on the console... so that must be there].

[Kuekuatsheu]

Ok. We booted from /stand/backup/vmunix and entered failsafe mode. We'll try to reset all kernel parameters to default with kctune.

Owen

[Kuekuatsheu]

Tried kctune and reset all values. Still won't boot. Can I recreate my /stand/vmunix using my backup kernel in /stand/backup/vmunix? Just to try and see if the system will boot.

>I changed the kernel parameter maxfiles and maxfiles_lim to 409600.

This looks like the results of your other thread:

400K is way too big. Who needs that many open files/sockets?

[Avinash20]

If you are able to boot from /stand/backup/vmunix, then just copy /stand/backup/vmunix to /stand/vmunix and boot the system
