IOPn.Diskx Commands
The IOPn.Diskx commands operate on mirrored SCSI disks and apply to mirror copying, mirror
disk availability, and bad block remapping operations. Table 5-11 lists the IOPn.Diskx
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.
