System panic after hpvmstop

Tim Medford — Thu, 10 May 2007 12:41:22 GMT

I've just completed setting up a new HP Integrity virtual machine. Everything was working great, read through the manuals and had installed the O/S and presented DVD, Network and other storage devices.

I had done multiple hpvmstop and hpvmstart commands with no problems. But the last time I did an hpvmstop the VM will no longer start. The only difference is that now I have HPUX installed on the VM. I wondered how that works, am I supposed to do a shutdown within the VM before doing an hpvmstop?

Anyway, I cannot get the o/s to load at all inside the VM now. I cannot even get into single user mode, it just keeps crashing. Any suggestions?

Here's the output from the Console log:

Hi,

the man page says
"HP recommends stopping
virtual machines using their native operating system commands."

Did you use the "-h" switch?
I guess even the "-g" will do a "reboot -h" only (not sure).
Now it looks like the root filesystem is damaged. If you cannot go to single user mode (probably not), consider to re-create or restore the backup.

use the following procedure to recover the unbootable VM:

assumption: you have another working VM on the same VM host. let's say, it's called 'goodvm'.

1. stop the unbootable vm.

2. stop the 'goodvm' on teh same vmhost.

3. remove the root disk from the bad vm.

4. add the same disk to the goodvm.

5. start the goodvm, import the new disk into a separate VG, calling it 'tmpvg'

activate the tmpvg on the goodvm, and fsck all the filesystems. for example:

fsck -y /dev/impvg/lvol3 -- this would be the /root of the badvm.

fsck -y /dev/tmpvg/lvol1 -- this would be the /stand of the boot disk of badvm.

... fsck remaining lvol on teh imported vg.

6. export the tmpvg from goodvm.

7. shutdown goodvm.

8. remove the disk from goodvm, add it back to the badvm.

9. start badvm. it should now boot up! :)

10. cheers!
