Cause of failure:

Since the AIX cannot be restarted normally when it is restarted, the above error occurred after the forced restart. This is because the forced shutdown caused damage to the partition of the system, showing a "The media is not formatted or the format is not correct" error, resulting in the partition not being mounted properly.

Solution:

Execute fsck to repair the disk partition

# fsck-p / data

* * Phase 1-Check Blocks and Sizes

....

* * Phase 6b-Salvage Block Map

-1 blocks missing

-1 blocks missing

Superblock is marked dirty (FIXED)

* Filesystem was modified *

After successful repair, the partition is mounted again, and the problem is solved.
