Software Failure (A500) strange behaviour

[Bill McNAMARA_1]

System boots normally via

ISL>hpux -is

# init 3

but panics via

ISL> hpux

Any ideas?

Later,

Hi Bill,

Do you have the error message ? Can you post it ?

HTH,

[Bill McNAMARA_1]

in fact it boots only with hpux -lm, NOT is

Sounds like you've got a bad boot disk, or disk that is in vg00, at 0/0/1/1.15.0.

Is 0/0/1/1.15.0 your primary or secondary boot disk? If your boot disks are mirrored you probably should be able to get the system boot multi-user by doing a 'hpux -lq' to boot without quorum. From there you can troubleshoot your disk problem.

Hi Bill,

Do you have a root mirror ?

Check this out for some possible solutions:

Hi Bill,

suspect at least one corrupt lvol.

When your boot -is OK, what happens, if you mount the remaining lvols manually one by one afterwards (may be a manual fsck before the mount will save you another panic ?)

Good luck
Volker

Hi Bill,

Try 'vgcfgrestore' without '-l' option. -l option will only list the config file. Try restoring the VG info.

I'll tell you tomorrow if it works, it's rebooting and I'm tired!
