I can confirm that LU is not safe at all. After luupgrade failed I should still be able to boot from primary BE. Reboot stop at grub prompt and I couldn't boot...
I already reinstall grub from NV70: # installgrub -m /mnt1/boot/grub/stage1 /mnt1/boot/grub/stage2 /dev/rdsk/c1t0d0s0 but this didn't help.I am still at grub prompt. Any idea how to solve this before reinstalling OS?
