Explanation

Marks a range of blocks as unusable on the disk and relocates any data allocated in that range. The remap command only relocates blocks. It does not correct or repair blocks that contain corrupted contents. The command uses a physical block size based on the SECTOR_SIZE disk group attribute. Repairs a range of physical blocks on a disk. The remap command only repairs blocks that have read disk I/O errors. It does not repair blocks that contain corrupted contents, whether or not those blocks can be read. The command assumes a physical block size of 512 bytes and supports all allocation unit sizes (1 to 64 MB).
