  • Page 95: Space

    SPACE Table 101. SPACE Command The SPACE command instructs the drive to set a new logical position relative to the current logical position. How this is done depends on the value of the Code field and the Count field. The Count field is a signed value that indicates the distance to move.

    TEST UNIT READY Table 102. TEST UNIT READY Command The TEST UNIT READY command returns Good status if a cartridge is loaded and ready. VERIFY Table 103. VERIFY Command The VERIFY command is supported by all drives. The VERIFY command causes data to be read from the tape and passed through the drive’s error detection and correction hardware to determine whether it can be recovered from the tape.

  • Page 97: Write

    WRITE Table 104. WRITE Command The WRITE command causes data to be transferred to the drive in a Data Out and written to tape. If the Fixed flag is clear, the initiator transfers a single block of the length indicated in Transfer Length.

  • Page 99: Write Buffer

    WRITE BUFFER Table 107. WRITE BUFFER Command The WRITE BUFFER command transfers data into the memory on the drive for the purpose of diagnostics, tests, or firmware upgrade. If the Mode field is 000b, then the data to be written is sent with a 4-byte header, which must be set to all zeroes.

  • Page 100: Write File Marks

    WRITE FILE MARKS The Write Set Mark (WSmk) field must be 0. Set marks are not supported. Table 108. WRITE FILE MARKS Command The WRITE FILE MARKS command causes a sequence of file marks to be written at the current logical position. The number of file marks to be written is indicated in the Count field.

    If it is of lower priority, it is ignored. The priorities are in the order listed above, with a reset being highest priority and a firmware upgrade being lowest priority. © Copyright IBM Corp. 2001, 2000...

  • Page 102: Persistent Errors

    Persistent Errors When errors occur that prevent tape operation, they are reported persistently until the problem is cleared. For medium-related errors (usually reported with a Sense Key of 3), the error is reported until the cartridge is successfully unloaded. For hardware-related errors (usually reported with a Sense Key of 4), the error is reported until the drive successfully performs a power-on self test.

    Drives that use a SCSI interface are able to respond to the INQUIRY, REPORT LUNs, REQUEST SENSE, and TEST UNIT READY commands within 250 ms of the reset line being released. The next command that is eligible for the Unit © Copyright IBM Corp. 2001, 2000...

  • Page 108: Abort Handling

    Attention Check Condition from each initiator gets a Check Condition status, with Unit Attention sense data for the reset. However, other commands may not be processed until the internal state of the drive has been reset. Any commands that allow Disconnects and cannot be processed are accepted and queued until the drive is ready to process them.

  • Page 110: Multi-Initiator Support

    Multi-initiator Support SCSI-attached drives support a maximum of two initiators on the same bus. Fibre-Channel-attached drives support a minimum of two initiators. The drive supports untagged queuing when operating with multiple initiators. If a command from one initiator is being processed when a command other than INQUIRY, REPORT LUNs, REQUEST SENSE, and TEST UNIT READY is received from a second initiator, the new command is queued.
