As there is only one LTO format defined at this time, the Cartridge Format value is
always zero. During insertion, the type of a data cartridge is unknown between the
time the cartridge is seated and the drive completes winding to BOT; the length
calculation takes place during winding.
Description
0 = The unit is not reserved. The Initiator Selection Address field is
invalid.
1 = An initiator has reserved the device. The Initiator Selection Ad-
dress field contains the Selection Address of the initiator.
0 = No reset in process.
1 = Bus reset (or Fibre Channel LIP) is in process.
0 = Cleaning is not needed.
1 = Cleaning is needed.
0 = No unforwarded command exists for LUN 1.
1 = One or more LUN 1 commands are awaiting forwarding via RS-
422.
0 = Load and thread when cartridge is inserted
1 = Load and do not thread when cartridge is inserted
2 = Do not load when cartridge is inserted
Autoload Mode is controlled by the Control Mode Page
Contains one of the values shown in the Cartridge Type Field Values
table below.
Always 0, indicating an LTO tape cartridge.
Uncompressed capacity of the cartridge, in multiples of 10
The current transport type of Port A, as specified in the Interface
Control Mode Page.
The current drive address of Port A as specified in the Interface
Control Mode Page.
The current transport type of Port B, as specified in the Interface
Control Mode Page. Zero in a Parallel SCSI drive.
The current drive address of Port B, as specified in the Interface
Control Mode Page. Zero in a Parallel SCSI drive.
Total number of hours of head-tape contact time.
Identification of the initiator holding a reservation on the drive, when
the Unit Rsvd field is one. If the interface is Parallel SCSI, then the
least-significant byte contains the initiator's SCSI ID; if the interface
is Fibre Channel, then the field contains the initiator's 64-bit world-
wide ID. If Unit Rsvd is zero, then this field is zero.
32 bytes of ASCII data, right-filled with blanks. This is the cartridge
serial number as defined by attribute number 0201h of the SPC-2
Read Attribute command. [The SPC-2 Read Attribute command has
not been implemented.]
