Chapter 5 Commands IOPn.Diskx Enable Bad Block Remap Warning: Using this command may cause the other member of this mirror set to become the target of a mirror set copy. Read all instructions in this section before continuing. Bad block remapping can be used to replace disk sectors containing bad spots with undamaged sectors during a mirror copy. This command permits the SCSI software to remap bad blocks automatically during a mirror copy for the source disk, indicated by Diskx. To enable bad block remapping for multiple devices, invoke this command multiple times - once for each SCSI disk for which you want to enable bad block remapping. This command can be issued before, during, or after a mirror copy. Sector numbers of remapped bad blocks are logged for informational and diagnostic purposes. Command IOPn.Diskx Enable Bad Block Remap Console Syntax MTCCONS IOPn.Diskx Enable Bad Block Remap Variables n - the ID number of the IOP (1 or 2) x - the ID number of the SCSI disk Results If a bad block on the mirror source disk causes remirroring to fail, you can use this command to enable automatic bad block remapping during a mirror copy. Bad block remapping is enabled for the device indicated by Diskx. When you enable bad block remapping, any additional bad blocks encountered are remapped, not just the one that caused the mirror copy to fail. It is possible that bad block remapping might cause file system information loss to occur, depending on whether the sector in which the bad block was encountered is in use by your file system. If the sector is not in use by your file system, bad block remapping causes no loss of file system information. After you enable bad block remapping for the device, use the command Reset Mirror Copy to cause mirror copying to begin again. Once the mirror copy completes successfully, the system automatically turns off bad block remapping. See Also IOPn.Diskx Disable Bad Block Remap IOPn.Diskx Reset Mirror Copy 105
