Explanation
After mirroring rootvg, bosboot must be run against the new disk to write a valid boot image to its boot logical volume so the system can boot from it.
Common mistakes.
- A. Updating the NVRAM boot list is the function of the bootlist command, not bosboot.
- B. Recording which disk the system will boot from is also the role of the bootlist command, not bosboot.
- D. bosboot writes a boot image to a single specified disk; it does not synchronize boot records between mirrored drives.
