Chapter 5 Commands 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. To negate previous commands that enabled bad block remapping 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 Variables n - the ID number of the IOP (1 or 2) 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.

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
. To negate previous commands that enabled bad block remapping
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.

Console Syntax
MTCCONS IOP

Variables
n
the ID number of the IOP (1 or 2)
x

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.
