boot mirror disk will not boot

Shawn McConnell — Thu, 13 Oct 2005 10:46:19 GMT

I am trying to get my boot mirror disk to boot up and when I type boot alt at the isl prompt it starts to boot and then comes back with the following.

EXEC_FAILED
EXEC Format error

Now here is how I created the boot disk mirror.

pvcreate -Bf /dev/rdsk/c2t2d0
vgextend vg00 /dev/dsk/c2t2d0
mkboot /dev/rdsk/c2t2d0
mkboot -a "hpux -lq (0/0/0.2.0;0) /stand/vmunix" /dev/rdsk/c2t2d0
lvlnboot -R

Then I recreated the mirrors

lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t2d0
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c2t2d0
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c2t2d0
lvextend -m 1 /dev/vg00/lvol6 /dev/dsk/c2t2d0
lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/c2t2d0

After I finished when I type lvlnboot -v it shows both disks as being bootable.

In your 2nd mkboot statement, try just this:

# mkboot -a "hpux -lq" /dev/rdsk/c2t2d0

Everything else looks OK.

when I rebuild a failed root mirror disk, I use the following sequence:

mirrdisk_raw=cXtYdZ # replace X, Y & with your own values
mkboot -l ${mirrdisk_raw}
mkboot -a "hpux -lq (;0)/stand/vmunix" ${mirrdisk_raw}
cd /usr/sbin/diag/lif
mkboot -b updatediaglif2 -p ISL -p AUTO -p HPUX -p LABEL ${mirrdisk_raw}

if you are on a 32 bit OS, replace the last line as follows:

mkboot -b updatediaglif -p ISL -p AUTO -p HPUX -p LABEL ${mirrdisk_raw}

not much different but again, I am not an expert how the bootstrap looks into the lif area and searches what. So, this works for me all the time and hope it works for you too..

It looks good except for
mkboot -a "hpux -lq (0/0/0.2.0;0) /stand/vmunix" /dev/rdsk/c2t2d0

Change it to
mkboot -a "hpux -lq" /dev/rdsk/c2t2d0

Do I need to redo the mirrors and everything or can I just type

mkboot -a "hpux -lq" /dev/rdsk/c2t2d0

no need to re-do the mirrors as they are not the part of this deal. This is just the few sectors at the beginning of your spindles.

Hi Shawn:

You have a space character between disk partition information and the filename of the kernel. You shouldn't need this anyway. I believe that is causing this problem.

Simply the command to be:

# mkboot -a "hpux -lq /stand/vmunix" /dev/rdsk/c2t2d0

...and you will be fine.

Regards!
