Boot problem

[Dimitri Karagiannis]

Hi everyone,

I'm working on an L2000 Class and I was getting Exec Failed: Cannot Find /stand/vmunix or /vmunix when I rebooted the server. I searched in the forums and found some information on booting with an alternate kernel but I couldn't find anything for the Lclass.

If anyone has some info on how to solve this problem it would much appreciated.

Thanks,

Dimitri

Hi Dimitri,
Try to interract with ISL, at the prompt type sea (search for bootable devices) if all seems ok boot pri -is (stay in single user) and see if you can find an explanation....

Good luck

Hi Dimitri,

you should proabably be a bit concerned if there is no /stand/vmunix file.

If you don't find a kernel on the box you won't be able to boot the box back up.

If you happen to know where a copy of the kernel file would be you could direct the booting to that file.

Is the box up or down at this point?

Dimitri,
Try to boot the system in LVM maintenance mode (hpux -lm). In maintenance mode uses the system another way to get the kernel entry point.

Hi,

First of all, all 800 series boot procedure is same, so there is nothing specific for L-class servers.

It seems that kernel "vmunix" is missing, So try the following:-

Initiate boot from the boot disk ( normally primary boot path )

at the ISL prompt enter the following to boot from the alternate kernel:

hpux -is (;0)/stand/vmunix.prev

it would be better to boot the system in single user mode with " -is " option as the kernel may not be upto date.

You can use "hpux ls" command to list all the files in the boot volume.

If there is no kernel available, u can use Support CD to recover OS.

regards,

Pramod
