SCSI Description
The REASSIGN BLOCKS Command reassigns one or more logical blocks to a spare
location(s) set aside for this purpose and records the reassignments in the Grown

No command-specific Control Descriptor Block fields affect the processing performed
for this command.
The list of Logical Block Addresses to reassign is supplied in the REASSIGN

List consists of a Defect List Header (Table 5-152) followed by zero or more Defect

List Header. If multiple Logical Block Addresses are specified, they are listed in
ascending order.
