/sbin/mkboot $boot_disk

man mkboot

You must do things such as lifcp after this to put the kernel loader and isl (hpux and ipl on the disk)

Search the forums for the correct procedure and scripts.

The procedure is like the procedure to create a mirrored root disk.
search for lifcp, mkboot pvcreate

Hi,

quote
//Use mkboot to place boot utilities in the boot area:
# mkboot -l /dev/rdsk/c0t5d0

Use mkboot to add an AUTO file in boot LIF area:
# mkboot -a "hpux" /dev/rdsk/c0t5d0

Or, use the -lq option to allow the system to boot in the event that one
of the disks is unavailable, resulting in a loss of quorum.

# mkboot -a "hpux -lq" /dev/rdsk/c0t5d0
NOTE: Use the -lq option when the root volume group contains only 2 disks.
If more than 2 disks are in the root volume group, the -lq option is not
needed as quorum will be maintained even if 1 disk fails.
Check the contents of the AUTO file with

# lifcp /dev/rdsk/c0t5d0:AUTO - //quote ends

cp /sbin/frecover $boot_disk

Not sure what are you trying to do here. Your boot device file is overwritten by the file /sbin/frecover ??

My guess is the aim was to destroy the boot area and recreate it. But the 'cp /sbin/frecover $boot_disk' will destroy the LVM header on the disk...
To only destroy the boot infor you could use 'lifcp /sbin/frecover $boot_disk:'

if it was only an lvm problem
hpux -lm
would boot, as would recovery cd, however, looks like your / filesystem is hosed too.

As far I can remember the LVM header for a boot disk is 4M.
Although I can't be certain of that...

Hello,

really not sure WHY you are doing this, but since you now have destroyed your boot-disk's LVM-header, and your LIF-area, have you got a backup (vgcfgbackup) of your boot-disk somewhere?
Then you might be able to boot from core-CD, get a shell, restore the LVM header (vgcfgrestore), restore the LIF-area (mkboot, and mkboot -a "hpux") and then you should be able to boot again...

Just my $0.02,
Wodisch
