Getting a System Panic when booting in maintenance mode.

[GIS-CGISS]

I can boot the system all the way up and also into single user mode with no problems but when I do a hpux -lm I get:
System Panic:

hmm..interesting..LVM maitenance mode uses the /stand/rootconf to locate the root and boot volumes. Boot in the single user mode and see if this file is present. May be this file is corrupt or something.

1) Remove the /stand/rootconf file and boot in multiuser mode. This should create the rootconf file.

Or

boot in single user mode and execute the lvlnboot -c command. This should create the rootconf file.

Now try booting in the maintenance mode and see if this helps

hi,

Check your bootstring. How are you booting in lvm maintenance mode.

is this the way you are going,

bo pri
interact with ipl
hpux -lm

or you are using a string with hpux command.

the coorect syntax would be

hpux -lm (;0)/stand/vmunix

Hope this helps.

If you can get to single user mode, you can run the following:

echo "0x0039ac28?i" | adb vmunix > hptrace
echo "0x003ef594?i" | adb vmunix >> hptrace
echo "0x0016837c?i" | adb vmunix >> hptrace
echo "0x0016a694?i" | adb vmunix >> hptrace
echo "0x002092b4?i" | adb vmunix >> hptrace
echo "0x0020f244?i" | adb vmunix >> hptrace
echo "0x006d0014?i" | adb vmunix >> hptrace
echo "0x0052ffb8?i" | adb vmunix >> hptrace
echo "0x006046a0?i" | adb vmunix >> hptrace
echo "0x00605324?i" | adb vmunix >> hptrace
echo "0x00603e20?i" | adb vmunix >> hptrace
echo "0x005fdacc?i" | adb vmunix >> hptrace
echo "0x004e23a0?i" | adb vmunix >> hptrace
echo "0x00177664?i" | adb vmunix >> hptrace
echo "0x001fd264?i" | adb vmunix >> hptrace

The file hptrace will contain a stack trace of the panic.

Allan, Did you try recreating /stand/rootconf file ?

Allan --
How similar are symptoms ?

Are you saying that you panic booting to maintanence mode or just that you have a "data page fault" ?

Data Page Fault is a generic panic for any bad address that is accessed so it can show up with a variety of root causes.
