Table 10-59 lists the syntax options for the remap command.

Table 10-59 Options for the remap command

Option	Description
`diskgroup`	Disk group name in which a disk must have data relocated.
`disk`	Name of the disk that must have data relocated. The name must match the `NAME` column in the `V$ASM_DISK` view.
`block_range`	Range of physical blocks to relocate in the format `start_range_number-end_range_number`.

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.

Examples

The first example remaps blocks 5000 through 5999 for disk DATA_0001 in disk group DATA. The second example remaps blocks 6230 through 6339 for disk FRA_0002 in disk group FRA
