Figure 8-3 ERASE CDB
ERASE causes data on the tape to be erased. Any write data currently held in buffer
memory and not written to tape yet is flushed to tape before the ERASE is executed.
Immed
If the Immediate bit is set to zero, the target will not return status until the selected
operation has completed. If the bit is set to one, status will be returned as soon as the
operation has been initiated.
Long
The Long bit controls the distance to be erased. If the bit is set, filler and EOD blocks
will be written if needed, and then the entire rest of the tape will be erased.
__________________________Note _____________________________
This command is an NOP on the DLT2000 unless the Long bit is set. Issuing
the ERASE command away from BOT is an ILLEGAL REQUEST.
