What procedure can be used to recover an AIX system that will not boot due to a corrupted boot logical volume?

SMS (System Management Services) mode provides firmware-level boot device selection and diagnostics but does not supply an OS-level shell needed to run bosboot or repair the BLV.

Restoring from a mksysb backup overwrites the entire rootvg and is a destructive, time-consuming approach when only the BLV needs to be repaired.

Booting from AIX installation media launches an environment independent of the system rootvg, allowing the administrator to access a maintenance mode shell. From there, tools such as bosboot can be run against the rootvg disks to recreate the corrupted boot logical volume without touching user data or requiring a full system restore.

This choice is identical to option B - a mksysb restore is a full rootvg overwrite and is unnecessary when the goal is to repair only the corrupted boot logical volume.
