i've mirrored the root disk of 18 GB to another one succesfully. so i can pull out the first or second drive, get an email of the event monitor, can work. after push back the HDD, syncing is running fine. so RAID 1 is working.
i can boot from the first drive "primary boot path", i can also boot from the second drive "alternative boot path. using SEA and BO.
my problem. if i pull out the first or the second HDD, i can't boot and use HPUX. its producing a system panic after displaying:
boot vmunix....
alloc_pdc_pages
see attachment.
is it normal ? so i can't boot if i have one broken HDD ?
or it's a problem with setting up RAID 1 for the root boot disk ? i used the LVM cookbook. i can boot from both HDDs if the other is in the system.
or it's a problem with hpux 11i dec2001 ? so i missed some important settings not covered in my LVM cookbook ?
system: rp5430 v11.11
thanks pete

Re: raid 01 boot problems
i used the command
mkboot -a "hpux (;0)/stand/peter"
and i missed the parameter -lq to deactivate quorum
so without second disk 50% of quorum is not there and system can't find vg00.
problem is that there is a system panic and no message cant activate vg00.....
i test it later
thanks peter

Re: raid 01 boot problems
Can you start in single user mode after removing the disk?..
make sure you have the Lastest hardware extension patches...

SolutionGo to BCH
boot from the disk which is still in the slot
When it says interact with IPL say YES
when in the ISL prompt type
hpux -lq
this will ignore quorum and boot. You defintly have a quorum problem.
To avoid this you can change the auto file on your boot disk using the mkboot -a command doing something like mkboot -a "hpux -lq" /dev/rdsk/cXtXdX.
this will automaticlly ignore quorum next time you boot
Good luck
Stefan
