Table 5–81 VERIFY Command Data - Field Descriptions
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.
