IOPn.Diskx Disable Bad Block Remap

Bad block remapping can be used to replace disk sectors containing bad spots with undamaged
sectors during a mirror copy.
This command negates any previous command that enabled bad block remapping for a SCSI
device, indicated by
Diskx
for multiple devices, invoke this command multiple times – once for each SCSI disk for which
you want to disable bad block remapping.
This command can be issued before or during a mirror copy. If you issue the command during
a mirror copy, it does not cancel any sector remaps that have already occurred. However, no
additional sector remaps will occur, and the copy halts if bad blocks on the source disk are
encountered.
Sector numbers of remapped bad blocks are logged for informational and diagnostic purposes.
Command IOPn.Diskx Disable Bad Block Remap
Console Syntax MTCCONS IOPn.Diskx Disable Bad Block Remap
n – the ID number of the IOP (1 or 2)
Variables
x – the ID number of the SCSI disk
Results If bad block remapping is turned on, but later you determine that automatic
bad block remapping is not desirable, invoke this command to stop the SCSI
software from automatically remapping bad blocks for a device.
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.
