LVM and boot problems after 11.0 split and 11.23 cold install

Vball23 — Thu, 23 Mar 2006 10:21:09 GMT

I have an n4000 that was running 11.0. I split the 11.0 mirror and cold-installed 11.23 on the primary drive and left 11.0 on the secondary drive.

Now, I can only boot into 11.0 or 11.23 by interacting with the IPL and booting hpux -lm.

Otherwise, if I just let it boot normally into 11.0 or 11.23, it gives me a software failure, panic and reboot.

This looks like a hardware problem. Your server appears to have a full PDT or page Deallocation Table, indicating you have had memory errors and pages have been deallocated, and it is trying to to it again at boot time, and this fails.
I woul dsuggest you log a call with your local HP Response Centre

It either has 3rd party memory or incorrectly installed memory, but if I clear the PDT, it still gives this failure immediately.

I believe these are 2 different issues and even if the memory issue is cleared up, I think the lvm problem will remain.

I have done these tests:

I booted from the 11.0 disk and specified hpux -lm. The server booted up fine.

I booted from the 11.0 disk and did not interact. The server crashed as above.

I booted from the 11.23 disk and specified hpux -lm. The server booted up fine.

I booted from the 11.23 disk and did not interact. The server crashed as above.

So, I can only boot into lvm maintenance mode and then into multiuser, so whatever lvm maintenance mode does to the filesystems automatically fixes the problem.

Any thoughts/suggestions?
