4.1 About This Command

The ERASE command causes the CTS to erase all tape from the

current valid tape position to the physical end of tape (PEOT). When

the erase operation is successfully completed, the tape is

automatically rewound to the logical beginning of tape (LBOT).

The ERASE command performs the erase operation at the same speed

as the READ and WRITE commands are performed; for example,

starting at LBOT, a 112m EXATAPE data cartridge will take

approximately two hours to erase.

Notes:

If the disconnect option is enabled, the CTS disconnects from the

initiator while executing the ERASE command. It does not

reconnect until the ERASE command has completed.

If the ERASE command is received after a WRITE (0Ah) or

WRITE FILEMARKS (10h) command, buffered data, filemarks,

and setmarks (8500c format only) are written to tape before the

erase operation is performed.

If an error occurs during the writing of the data in the buffer to

the tape, the CTS returns Check Condition status. The erase

operation is not performed. The initiator should issue a REQUEST

SENSE (03h) command to determine the cause of the error.

The erase operation cannot be interrupted once it has started.

Using the ERASE Command on a Partitioned Tape (EXB-8505

Writing in 8500c Format Only)

When the tape loaded in the EXB-8505 contains two partitions, the

ERASE command operates on just one partition at a time. When the

erase operation is finished, the EXB-8505 rewinds the tape to the

beginning of that partition. To erase the data from the entire tape

without eliminating the partitions, you must erase both partitions

separately. Refer to Section 3.7 starting on page 3-23 for detailed

information about using the ERASE command and performing other

operations on partitioned tapes.
