Figure 164. WRITE SAME (41)
The Write Same command instructs the Target to write a single block of data transferred to the Target
from the Initiator to a number of sequential logical blocks. This command is useful for writing large data
areas without sending all of the data over the SCSI bus.
Ÿ
Logical Block Address specifies the address at which the write begins. The Number of Blocks
specifies the number of contiguous blocks to be written. If the number is zero, all of the remaining
blocks on the specified Logical Unit are written.
Ÿ
RelAdr (Relative Block Address) is not supported and must be set to be ZERO.
The data for this command is not retained in the cache.
