Figure 127. REASSIGN BLOCKS (07)
The REASSIGN BLOCKS command requests the drive to reassign a logical block to an available spare.
The REASSIGN BLOCKS command attempts to allocate spare blocks on a spare track. The logical
block address is transferred to the drive during the DATA OUT phase. One to four block(s) may be
specified for relocation per REASSIGN BLOCKS command.
Reassignment is complete upon the completion of the REASSIGN BLOCKS command. At this time, the
defective logical block address has been added to the grown (“G” list) defect list.
Data contained at the logical block address being reassigned is not preserved by the drive and is filled
with a constant pattern.
