Field Name
Description
Immed
Immediate. When set to 1, the VERIFY command completes before
any tape medium movement is done (that is, when the processing
has been initiated.
BC
Byte Check. When set to 0, the tape drive performs an internal
CRC/ECC check of data. No data is transferred to the initiator.
When set to 1, the command is rejected.
Fixed
This bit specifies whether fixed-length or variable-length blocks are to
be verified.
When set to 0, variable-block mode is requested. A single block is
transferred with the Verification Length specifying the maximum
number of bytes the initiator has allocated for verification.
When the Fixed bit is set to 1, the Verification Length specifies the
number of blocks to be verified. This is valid only if the logical unit is
currently operating in Fixed Block mode.
Verification Length
This field specifies the amount of data to verify, in blocks or bytes as
indicated by the Fixed bit.
