Can any one help?

Did you perhaps migrate rootvg to another disk?

What I do at that point is on next boot, go through SMS menu and choose the boot disk manually, then afterwards:

bosboot -a -d /dev/hdiskXX -l /dev/hd5

Yes, the rootvg was migrate.
But i have migrate a lot of Systems and this is the first who makes this problem.

I will try your Tip after the next reboot.

You could also try

cd /dev
ls -l rhdisk*
ls -l ipldevice

You'll see that ipldevice has identical major and minor device numbers as your old boot disk (in fact it is just a second name for that rhdisk as indicated by the link count of 2), so:

rm ipldevice
ln rhdisk14 ipldevice

Then try bosboot again. If it still doesn't work, try my first suggestion via SMS menu on boot.


HTH,
